Programming Details
Java is a high-level programming language originally developed by Sun Microsystems and released in 1995.
Java runs on a variety of platforms, including Viper (Linux), Windows, and Mac OS.
Programming example
public class MyFirstJavaProgram {
/* This is my first java program */
public static void main(String []args) {
System.out.println("Hello World"); // prints Hello World
}
}
Modules Available
The following modules are available:
- module add java/jdk1.7.0_80
- module add java/jdk1.8.0_102
Compilation
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
