Hire the best Java developers on contract

Java is an extremely popular open-source programming language as well as a computing platform. Java was first released in 1995 by Sun Microsystems. Later on, Oracle acquired Sun Microsystems, so Oracle now owns Java.

Java is a fast and secure programming language that can be used to create applications ranging from mobile apps to enterprise-level software. Currently, there are over 3 billion devices that run on this language. 

JUnit is a popular Java unit testing framework. It helps in evaluating whether the program works as per the expectation or not.

Java is a programming language, whereas JavaScript is a scripting language. The Java code needs to be compiled, whereas the JavaScript code is written in text and only requires to be interpreted. 

Let’s understand what makes Java Development so popular:

• Java has been around for a really long time now. No wonder it has a plethora of learning materials for programmers. From sophisticated documentation to comprehensive books – Java has it all. It also has an active community to support Java developers whenever they get stuck with something. All this makes Java a reliable choice for application development. 
• Java provides several tools to automate debugging, testing, as well as deployment. Tools like Java profiles help in java memory leak detection. All these tools help Java developers in saving time while developing Java applications. 
• There are no platform restrictions for Java. It can run on any operating system, be it Windows, Linux, Android, or iOS. This allows Java apps to run on multiple devices without rewriting the code. 
• Java is filled with premade libraries and functions. While programming, Java developers don’t need to write every new function from scratch. Instead, they can use the libraries to speed up the development process. 

Java performance testing is a process to monitor the performance of applications made with Java. Metrics such as resource utilization, response time, and scalability are measured in performance testing. Let’s check some popular Java performance testing tools:

• JMeter: Jmeter is an open-source performance testing tool by Apache. It is primarily used for load and stress testing of Java applications. Its open-source nature makes it a popular choice in the Java development community. 
• LoadNinja: LoadNinja is a cloud-based tool that helps in testing java web services and web applications. It helps Java developers in ensuring that their web applications are robust. It uses real browsers for testing instead of load emulators. LoadNinja also offers browser-based metrics along with several other analytics features. 
• BlazeMeter: BlazeMeter provides Java performance tests for web apps, mobile applications, APIs, and Java microservices. 
• Zipkin: Zipkin is a performance testing tool for troubleshooting issues in distributed service architectures. It lets java develops to visualize traces through dependency diagram. It also has an open-source version called OpenZipkin. 

While hiring a Java developer, you should take a thorough look at their experience level, past projects, and technical skills. At SkillDB, you can find an wide range of Java developers with varying degrees of experience and skills. You can shortlist the ones that fit your project’s needs.
