Introduction of Java
Java is a high-level programming language created by James Gosling from Sun
Microsystems (Sun) in 1991. The target of Java is to write a program once and
then run this program on multiple operating systems. The first publicly available
version of Java (Java 1.0) was released in 1995 and latest version of Java 10.0. Sun
Microsystems was acquired by the Oracle Corporation in 2010. Oracle has now
the steer man ship for Java.
