Today there are about 700 programming languages. Java is among the most requested tools. The scope of the language is very wide, respectively, developers may be needed in a variety of areas. For this reason, it is sometimes difficult to find a great Java developer, some companies decide to outsource Java development. If you are looking for a Java developer, then this article is for you. We will give you recommendations on how to attract the best employees to the project.

How and Where to Find a Java Developer?

The selection of a Java developer is a very responsible task since the quality of product development and its future depend on it. Let’s look at the factors that you should definitely consider when looking for a specialist.

Define Project Requirements

First of all, you need to determine the requirements of your project. They should be based on company goals or how your product can meet customer goals and needs. In addition, it is necessary to form a vision for the product in the long term and think over strategies for monetization and product improvement.

Define the Category of Development

Every Java project is different. Therefore, you must know what the requirements of your project are. Before hiring IT staff (remotely or in the office), it is important to classify your project.

• Java web development. Hire a full-time Java developer experienced in building easy-to-use web applications.
• Custom java application. If you have a unique business requirement, be sure to enlist the help of a senior developer. He has experience building enterprise applications.
• Java game development. Hire a lead Java application developer who knows about Meta and Screenkit used to create game applications.
• Java product development. Find a Java application development company where programmers know about ideas, validation, requirements assessment, and implementation.
• Java system integration. Integrate a Java application with the framework of your choice when you have trusted experts by your side.
• Upgrading and migrating Java applications. Certified Java experts are always up to date with the latest tools and frameworks.
• Maintenance of Java applications. Every application requires ongoing maintenance as well as support. So, cooperate with developers who know how to do this.

Make sure you know which category your project belongs to, then hire Java developers according to the requirements.

Specialization

To create a team of experienced Java developers that meets the needs of your project, it is important to hire programmers who have years of experience in the industry. It will help you get highly optimized Java programming solutions.

In today’s results-driven industry, it’s more important than ever to partner with a development team that delivers best-in-class services.

Frameworks and Technologies

There is a long list of mobile and web applications that can be created using the Java programming language. Different Java development tools allow developers to achieve different results. Several frameworks include JSF, Grails, Plat, Spring, Maven, and more.

You may run into a situation where Java developers are aware of various frameworks but not the one you are looking for. Therefore, before selecting IT specialists, double-check whether the expert has the relevant knowledge and experience.

Selection Process

Before hiring a developer or development team, make sure you like it. Also, go through multiple interviews with the development team you’ll be working with and see if they’re capable enough. List of core skills that will allow you to appreciate the experience of Java developers:

• Object Oriented Programming Concepts;
• Core Java Theories;
• Java Developer Certificates.

You should also interview them on technical parameters:

• Development skills. Knowledge of JDBC, RESTful, and design patterns;
• Tools. Java experts should be experts in Seam, HIbernare, Android Studio, GradleMaps Store as well as Spring, ORMLIte, Corona SDK, and Caching Touch.

The strengths of Java developers should include wireframing, user interface design, conceptual design, AR, and APIs. Recheck the skill set required and then make your final decision. Not every developer will have all the skills mentioned above and then mix and match to create a brilliant team.

Questions to ask all Java developers in an interview:

• What is the importance of main() in Java?
• Difference between path and class.
• What is the last Java keyword?
• What is Enum and Composition in Java?
• Do you know about the Java Reflection API?
• Explain user and daemon flow
• CountDownLatchC function
• Compare and Swap Algorithms
• OutOfMemory error
• Explain JDBC
• What is biphasic fixation?

Lots of Satisfied Customers

Testimonials are social proof of satisfied customers as they provide enough confidence in developers and their reliability. Your projects will be successful if the team is passionate enough to work.

One thing you have to take care of is whether the testimonials are genuine or not. You can also rely on Google and AngelList reviews.

Comprehensive Service

What if you need not only Java development services, but also design, development, testing, and more? In this case, partner with an outsourcing company that can offer you comprehensive services and still take good care of your project.

In addition, it will help you avoid unnecessary hassle. In addition, the programmers you hire must understand the value of your business secrets, source codes, data, and various information that you provide to them during an NDA.

Conclusion

Developers are creative people. Many of them work not for the sake of money (although the level of payment is also important), but for self-realization. To attract the best developers, you need to explain why your project will be interesting for a programmer, what unique experience he will get, or what important problem he will solve.

The services of good developers are not cheap, but it is not worth saving on programmers. In practice, experienced programmers work faster, and sometimes cost less, if you sum up all the costs of the project, its refinement, bug fixes, and testing. If you have trouble finding Java for a developer or an entire team of developers, we recommend that you contact Alcor. The company has many years of experience and deep knowledge in the selection of valuable employees for IT companies from Eastern Europe, including developers and managers.

With Africa’s share of the global workforce projected to become the largest in the world by 2100, it is critical for African countries to increase the uptake of digital technologies* to drive employment growth for the more than 22 million Africans joining the workforce each year, emphasizes a new report released today.

The “Digital Africa: Technological Transformation for Jobs” report provides a comprehensive analysis of how digital technologies can enable economic transformation and boost jobs in the region. It also sheds light on how policy and regulatory reforms can widen the availability and increase usage of digital technologies.

Of all the regions in the world, Sub-Saharan Africa (SSA) displays the largest gap between the availability of digital infrastructure and people’s actual usage. On average across countries in SSA, 84% of a given country’s population had at least some level of 3G mobile internet availability and 63% had some level of 4G mobile internet services, but only 22% were using mobile internet services at the end of 2021, according to numbers collected by the Global System for Mobile Communications Association using a methodology focused on unique subscribers. Usage rates range from a low of 6% in South Sudan to 53% in South Africa, underscoring the heterogeneity of average use and the need for differentiated policy reforms across countries.

“The minimal usage of mobile internet is a lost opportunity for inclusive growth in Africa,” said Andrew Dabalen, World Bank Chief Economist for Africa. “Closing the uptake gap would increase the continent’s potential to create jobs for its growing population and boost economic recovery in a highly digitalized world.”

Even though technology and innovation are known to drive long-term economic growth and can lead to much-needed modernization in economic activities across agriculture, manufacturing and services, the digital divide continues to grow between large formal and micro-sized informal enterprises, between young men- and older women-owned enterprises, and between richer, urban, and more educated households and poorer, rural, and less educated households. Only 2% of micro-sized firms owned by young women and 8% of micro-firms owned by young men use a computer.

The report highlights evidence that internet availability has a positive impact on creating jobs and reducing poverty in African countries. For example, in Nigeria, labor force participation and wage employment increased by 3 and 1 percentage points, respectively, after three or more years of exposure in areas with internet availability. Job estimates for Tanzania found that working-age individuals living in areas with internet availability witnessed increases of 8 percentage points in labor force participation and 4 percentage points in wage employment, after three years of exposure. Moreover, the proportion of households falling below the national basic need poverty line dropped by 7 percentage points.

 “To transform internet availability into productive usage and job growth, the region needs affordable access, digital skills and digital technologies that meet the needs of Africans,” said Christine Zhenwei Qiang, World Bank Global Director for Digital Development. “Continuous sector reforms and targeted public investments that support digital economy foundations and digital uptake can help close the digital divide and unleash tremendous potential for more and better jobs for Africa’s growing population.”

For the 40% of Africans who fall below the global extreme poverty line, the cost of basic mobile data plans is often out of reach. Small and medium-sized businesses in Africa also face more expensive data plans than businesses in other regions. To bring down costs, governments should aim to promote competition in the provision of digital infrastructure and reduce operational costs.

To boost productive usage, governments should implement policies that support the development of more attractive digital solutions geared to the skills and productive needs people have while building broader awareness and education. Policies that foster innovation and support digital start-up entrepreneurs are essential to ensure that more Africans use the internet for jobs and learning, which will lead to higher standards of living. When digital technologies better meet the needs of people, households and firms, demand for their use will also increase, making internet expansion more commercially viable, and supporting a virtuous cycle of technology-led transformation.

*For the purposes of the report, digital technologies are defined broadly to include not only digital and data infrastructure, broadband internet, smartphones, tablets, and computers, but also a wide range of more specialized productivity-enhancing digital solutions ranging from communications, management upgrading, and worker training to procurement, production, marketing, logistics, and financing.  

Reducing everyday offences may depend on harnessing the power of virtual reality, conscious design and community spirit.

By Alex Whiting

Picture a young offender with a headset immersed in a virtual room, coming face to face with an avatar of his or her future self.

The person tells the avatar about his or her lifestyle, substance abuse, debts or time hanging out with delinquent friends. Then the person travels forward through a 3D representation to become a future self and give the younger one advice.

Facing the future

Enabling people to speak to their future selves and ask for advice could help them make better choices today, some scientists say.

‘If people care more about their future selves, we think they will be less likely to engage in delinquent behaviour in the present,’ said Jean-Louis van Gelder, a professor of criminology at Leiden University in the Netherlands. He is also director at Germany’s Max Planck Institute for the Study of Crime, Security and Law.

Van Gelder and other researchers in the EU are taking inspiration from the world of gaming to help bring home to young offenders the longer-term consequences of their choices. Although the technology is still being tested, the early signs are that these 3D virtual representations could help change behaviour for the better.

It’s one of many crime-prevention techniques being developed across Europe.

People who live in a day-to-day survival mode are more likely to commit crime or to abuse drugs and alcohol. That’s because these types of behaviour deliver immediate, albeit small, benefits. The severe costs – including prison – are often in the distant future.

Such short-term mindsets can result from harsh or unpredictable parenting and exposure to delinquent friends or poor role models, according to Van Gelder.

Short-sightedness and impulsivity are often believed to become relatively fixed in children by the age of 10 years, and it is hard to change. But what scientists are beginning to discover is that it can in fact be worked on, opening up the potential to help people stop committing crimes.

Do-it-yourself advice

He tested the virtual-reality technology with 24 young offenders as part of an EU-funded research project called CRIMETIME, which runs through March 2024.

‘The interesting thing is that people give themselves very sound advice generally,’ said Van Gelder, who coordinates the six-year project supported through the European Research Council. ‘People tend to tell themselves to stop committing crime or to be more disciplined or to look for a job.’

Participants were asked about their behaviour and attitudes in the week before and after the session. The majority reported less harmful or criminal behaviour and greater awareness of their future selves after the session.

It’s extremely difficult to change people’s behaviour, according to van Gelder.

‘The changes were not large, but we saw a reduction, which tells us that we’re on the right track,’ he said. ‘So our hope is that getting advice from themselves will be more convincing than getting advice from other people.’

The next step is to develop a mobile phone app that will give them a similar experience and could be used every day for several weeks.

‘The more they do the exercise, the more vivid their future self becomes,’ said Van Gelder.

And the more connected they feel with their future selves, the more marked the impact on behaviour.

Design deterrents

An EU-funded project called Cutting Crime Impact (CCI), which ran for three years until end-2021, focused on more practical ways of preventing crime. These include making buildings, benches, bags and the like harder to target.

‘You can actually design out crime,’ said Professor Caroline Davey, director of the Design Against Crime Solution Centre at the University of Salford in Britain.

She coordinated CCI, which covered seven European countries: Estonia, France, Germany, the Netherlands, Portugal, Spain and the UK.

Since the 1990s, theft from homes and cars has fallen with the design of more secure doors, windows and burglar alarms.

‘We’re always trying to encourage designers to think about the risks associated with their particular products,’ said Davey. ‘It’s not rocket science – it’s fairly easy to predict what will be attractive to potential offenders.’

For example, the back of a bench that has gaps large enough to put two fingers through to reach someone’s pocket or bag will encourage pickpockets. By contrast, designing buildings so that neighbours overlook each other deters burglaries.

Researchers have worked with Britain’s Greater Manchester Police to develop a service to advise architects, urban planners and property developers on crime prevention.

‘They highlight the risks in a particular area and advise them on how they can reduce those risks,’ said Davey.

Police tips

Similar approaches were crafted under CCI with law-enforcement agencies in most of the participating countries. Police in Estonia’s capital Tallinn took part. They report that crime has plummeted in Tondiraba Park – a large public space in the city – since it was revamped in cooperation with the police.

Kelly Miido, senior superintendent in charge of community policing in Tallinn’s Mustamäe-Kristiine district, said she and her colleagues had to work hard to get local authorities and urban planners to think about potential security risks in their designs and ways to remove them.

‘We had to constantly remind planners that we wanted to be part of the process,’ Miido said.

Now, however, planners and local authorities approach her team to ask for design help.

‘They have found that, if they involve us, they have fewer problems in the long run,’ Miido said.

Before the redesign, the local police had to send a patrol every day to the park during the summer. Now they are called out two or three times a week.

Local knowledge

One of CCI’s most important results is a handover process for when community police officers are redeployed, according to Davey, who coordinated the project.

Such patrollers, who walk the streets and get to know locals, play an important role in preventing crime. Because people can talk to them informally, these officers learn a lot about neighbourhood concerns and troubles, including in relation to social vulnerability and radicalisation.

‘Community policing is so important, but is often undermined by lack of funding and appreciation for what these officers do,’ said Davey.

That is reflected in the way that officers can be redeployed with no handover process. Relationships built up over years with a community can be lost overnight.

‘The community aren’t told about the change and often organisations the police officer works with – like social services and schools – don’t know,’ said Davey. ‘This can have a significant impact on people’s trust in policing and, ultimately, their quality of life.’

A handover system addresses the matter with relative ease and at low cost. It involves the redeployed officer and his or her replacement walking the area together and meeting key people.

‘It captures something very human and important, which is the relationships that exist between community police officers, local people and local organisations,’ said Davey.
