Java

JAVA is Free: Unlike programming languages like Dot Net where you need to pay Microsoft to get license copy software for application development, JAVA is FREE to download. Due to this JAVA is very popular over other paid programming languages.

 Java easy to learn:  JAVA programming is easy to learn was compared to C or C++. JAVA has a similar syntax like C++.

 JAVA is Platform independent: JAVA stands true to its tagline "Write once and run anywhere". You create JAVA applications in Windows and run it in Linux or other operating systems and vice versa.

 JAVA Open source Libraries:  JAVA has a rich set of API and Documentation, which helps in developing your applications faster. Java has global talent pool to help.

 Garbage Collection:  JAVA has a powerful memory management technique i.e. called garbage collector, so Programmers do not have to worry about memory issues in application.
