How to install the gcj Java compiler on Debian 7.0 and compile a simple program.

This is how to compile a Java source file on Linux with gcj.

homer@neo:~/Documents$ gcj --main=HelloWorld HelloWorld.java

This is the source file that I am working with.

/*
 * My first Java program.
 *
 */
 
import java.util.Date;
 
public class HelloWorld {
 
	public static void main(String[] args) {
 
		System.out.printf("\"Hello, World\"\n");
		Date date = new Date();
 
		System.out.println("The date is: " + date.toString() + ".");
	}
 
}

And after I have compiled the program, I can run it by typing ./a.out and I will see the output.

homer@neo:~/Documents$ ./a.out 
"Hello, World"
