What is JAVA:-

Java is a computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere" (WORA), meaning that code that runs on one platform does not need to be recompiled to run on another. Java applications are typically compiled tobytecode (class file) that can run on any Java virtual machine (JVM) regardless of computer architecture. Java is, as of 2014, one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers. Java was originally developed by James Gosling at Sun Microsystems (which has since merged into Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them.

History:-

Java was designed by Sun Microsystems in the early 1990s.
Basic aim of java was to solve the problem of connecting many household machines together.
Project was unsuccessful because no one wanted to use it.
Earlier Name of Java : OAK

As there was another language called Oak , they decided to rename OAK. New name was given to OAK , OAK was renamed Java in 1994
Java was publicly released on : May 27, 1995
Java was targeted at : Internet development
Applets Had early support from companies :Netscape Communications

5 Principles of JAVA:-

It should be "simple, object-oriented and familiar"

It should be "robust and secure"

It should be "architecture-neutral and portable"

It should execute with "high performance"

It should be "interpreted, threaded, and dynamic"
