Thread: Installing Eclipse/Java on Ubuntu

i have installed eclipse can't run java code. lots of different errors including:

unsupported major.minor version 51.0

or

in ide errors like:

"implicit super constructor object() undefined default constructor. must define explicit constructor."

have eclispe, icedtea java 6 web start (whatever is) , openjdk java 6 runtime installed.

code runs on multiple windows machines correctly.

have tried run code via terminal don't know how edit .bashrc correctly can use javac. don't know path meant set.

i'm not super familiar eclipse -- know weird things, has own compiler, etc.

first, make sure have installed:

code:

sudo apt-get install openjdk-6-jre icedtea6-plugin openjdk-6-jdk

and check it's set correctly:

code:

java -version

code:

javac -version

it should like

code:

java version "1.6.0_23" openjdk runtime environment (icedtea6 1.11pre) (6b23~pre11-0ubuntu1.11.10) openjdk client vm (build 20.0-b11, mixed mode, sharing)

and

code:

javac 1.6.0_23

respectively.
