What is Java? Java is an object-oriented programming language developed by Sun.

Using the Software
To compile and run a java program on Ovid or Vergil, at the system prompt type:

% javac file.java

% java file

where file is the name of a java program with the file extension .java. Here is a tiny example:

The program is named "echo.java":

// This program echoes the arguments that you type in.  To test it
// you do this:
// javac echo.java
// java echo a b c d e f
//
public class echo{
  public static void main(String argv[]) {
     for (int i = 0; i < argv.length; i++)
        System.out.print(argv[i] + " ");
     System.out.print("\n");
     System.exit(0);
  }
}

which you compile and run as Ovid or Vergil as follows:

% javac echo.java
% java echo a b c d e f
