Java History

HISTORY OF JAVA:

( C++ s an machine dependent language e,g if we run a C++ prog on any other machine it wouldn't run totally correct.)

JAVA was introduced by SUN microsystem in 1991, which isn't machine dependent because it uses a Virtual Machine ,,,, then Ms developed Visual J to compete java which was an exact copy of java

James Gosling, the father of Java, was intent on building a low-cost, hardware-independent software platform using C++. For a number of technical reasons, C++ was dropped, and a new language, called Oak, was developed, based on C++, but eliminating its shortcomings. These shortcomings include problems associated with multiple inheritance, automatic type conversion, the use of pointers, and memory management.

After some time, Oak was renamed Java,
