What does the program print on the monitor when it runs?

Answer:

The variable contains: 123


Simulated Java Program

To get the most out of these notes, copy the program to a text editor, save it to a file called Example.java, compile it, and run it. See a previous chapter on how to do this. For a simulation of running the program, enter an integer in the text box below and click on "Compile", then click on "Run". (If this does not work your browser does not have JavaScript enabled.)

This is just a simulation (using JavaScript), so it is not exactly like compiling and running a real Java program. Don't take it too seriously. Please do the real thing if you can.

Try this page: http://ideone.com/. There, you can paste Java code into a web page text box, and then compile and run it with actual Java.

  public class Example
  {
    public static void main ( String[] args )
    {
      long payAmount = ;    // declaration of a variable
  
      System.out.println("The variable contains: " + payAmount );
    }
  }

QUESTION 4:

Try entering something like "rats" in the declaration. Does the program compile successfully?
