“Java is an object-oriented programming language whose history dates back to 1994 when Sun Microsystems came up with an idea of a programming language that can be compiled and executed independent of the machine on which it is used,”
Java was taken over by Oracle in 2010, so its certifications are now governed and provided by Oracle Inc. The certifications follow a fixed order based on expertise. Oracle also provides classroom training programs before certification exam.
Students can also directly opt for certification exam wherein they will have to clear a rigorous test on Java programming at its respective level. Successful completion of test will qualify the candidate for a certification signifying his/her excellence at that level.
