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.)


class Example
{
  public static void main ( String[] args )
  {
    long payAmount = ;    //a declaration of a variable

    System.out.println("The variable contains: " + payAmount );
  }
}

Simulated Monitor




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

QUESTION 4:

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