History of java
Several versions of Java exist today ever since Sum Microsystems released the first version of Java i.e. JAVA 1.0. This was followed by an updated version, JAVA 1.1. When Sun released the next version, Java 1.2, they changed the name of the language to JAVA 2. Please remember that 2 is part of the name and not the version number. So that version of the language was known as Java 2 version 1.2. The next version was Java 2 version 1.3. The current version is Java 2 version 1.4.
Let us show the history of JAVA in a tabular form.
