Programmers who are familiar with the syntax of C and C++ will be able to relate to Java very easily. It was first developed by Sun Microsystems and later owned by Oracle Corporation. Java is one of the most popular programming languages used today. The source code files created in Java are assembled in the bytecode format. The files are then run by a Java interpreter. Most computers having operating systems such as UNIX, Macintosh OS, and Windows can read compiled Java source codes because they come pre-installed with Java interpreters and runtime environments, which is also known as Java Virtual Machines. Many web-based and computer-based applications are heavily dependent on Java. Apply from the latest java development jobs present in this section.
