Unable to run java file from command like Ubuntu
- by KodeSeeker
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
