Java is recognized as a highly popular and extensively language that is used for programming. Originally developed by James Gosling, it entered the market in 1995. The language has its syntax in common with two other important programming languages i.e. C and C++. But one of the distinguishing factors is that it features an object model which is quite simpler with minimum low-level facilities. It is regarded as much-favored languages owing to its automatic memory management. The core task of a Java developer is to determine the time when these objects are created, leaving its runtime task to free memory at a time when objects are idle and not in use.
