}
}
Modules Available
The following modules are available:
- module add java/jdk1.7.0_80

The program would be compiled in the following way, which is a choice of Java JDK available.
- Javac - is the JAVA byte compiler
- Java - is the JAVA runtime
[username@login01 ~]$ module add java/jdk1.7.0_80 (or module add java/jdk1.8.0_102) [username@login01 ~]$ javac MyFirstJavaProgram.java [username@login01 ~]$ java MyFirstJavaProgram Hello World
