Java Developer Resume, Skills, and All You Should Know About the Coders
Java is an object-oriented coding language able to produce software for multiple platforms without the need to compile and adapt it. The bytecode of the language runs on most operating systems, on PCs and mobile devices. Java has been first released in 1995 by Sun Microsystems. Its developer is James A. Gosling, a former computer scientist of the company.
Now Java is everywhere: in powerful supercomputers, laptops, gaming consoles, smartphones. There are billions of websites and applications working on it. The developers around the globe love Java because it is easy in all the aspects of use: learning, writing, compiling and debugging. That’s why you can find so many Java developer resumes on all job sites as well as the demand to hire Java developer.

How to Choose a Qualified Java Developer?
Giving the popularity of Java, thousands of developers join the market every day. Finding a programmer who can contribute to your project and build a reliable code is not easy. To avoid pretenders, follow these tips when screening and interviewing on-demand developers.
Prioritize practice over theory.
There are hundreds of Java manuals, so learning the theoretical framework of the language doesn’t take much time or effort. As a project manager, you want to rent a Java coder that can bring more than the knowledge of fundamentals to the table. Encourage the candidate to share cases and working experience so that you can assess how well-versed a developer is in Java best practices.
Make sure a developer has a command of a few versions of Java.
Asking a candidate about which release is better for the project is a way to test how familiar a software engineer is with newly added features, their advantages, and drawbacks.
A developer has to know his way around frameworks.
There are loads of Java frameworks – Node, jQuery, Firebase, and more. A developer needs to have a strong command of a framework the team uses for development.
Development kits and API knowledge.
An experienced developer will not miss out on using JDKs and tools to make the most out of the language. During the interview, ask a candidate about his use of build environments as well as the experience with REST and SOAP.
Make sure your working methodologies match.
If you work in Agile, it’s better to rent a coder Java who, in his turn, favors the framework over alternatives. This will protect both of you from miscommunications and bottlenecks.
