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 Chapter 7 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". (Note: 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. 


  
  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?
