This post describes about how to install Eclipse on Ubuntu system. 

Step 1 : 

Install Java package using apt-get command,

~$ sudo apt-get install openjdk-7-jdk

To check the current version,
 
~$ java -version

java version "1.7.0_91"
OpenJDK Runtime Environment (IcedTea 2.6.3) (7u91-2.6.3-0ubuntu0.15.04.1)
OpenJDK 64-Bit Server VM (build 24.91-b01, mixed mode)



Step 2 :

Before download Eclipse make ensure your  operating system whether 32 bit or 64 bit, download eclipse packge using wget command

32 Bit:

64 Bit:
