INTRODUCTION
JAVA is an object oriented Language
It is platform independent. Whenever the JAVA program is compiled, it is converted into Bytecodes which can be executed on any machine.
It is the only language that is used for Window Application Development, Web Application Development and Mobile Application Development.
It is a secure language as its code can run in JAVA Runtime Environment (JRE) only. There is not any interference of additional software even not of an OS.
There is no implementation dependency like a specific version of a software is required. This makes JAVA is portable language. Java code written in one machine can be interpreted/executed in another machine due to its portability.
It is multithreading language that means a program written in JAVA can perform multiple task simultaneously. Execution of multithreads at the same time helps to utilize the same memory. That saves memory and makes execution faster.
