How to run a simple java program in eclipse?

Question

Below is my Java code:

public class MainClass {

    /**

     * @param args

     */

    public static void main(String[] args){

        char c = args[0].charAt(0);

        char c1 = (char)(c + 1);

        System.out.println(c + "\t" + c1);

    }

}

When I try to compile it in Eclipse, I get the below error:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0 at MainClass.main(MainClass.java:9)

Can anyone tell me how to Run a Simple Java Program in Eclipse?
