java

I'm a newbie to Ubuntu and Im looking to run Java code from the command line. Ive checked that path as well. The interesting thing is the code compiles but fails to run

ie.

user@ubuntu:~/py-scripts$ javac Main.java' works well.

but when I do .

`user@ubuntu:~/py-scripts$ java Main

I get the following error

Exception in thread "main" java.lang.UnsupportedClassVersionError: Main : Unsupported major.minor version 51.0
