Live Code!

Here is some code that illustrates changing the loop control variable by an amount other than one.

// Note: GREATER-than-or-equal operator
//

count =  ;

decrement =  ;

while ( count >= 0 )  
{
  System.out.println( "count is:" + count );
  count = count - decrement;
}
System.out.println( "Count was " + count 
    + " when it failed the test");

(The output window sometimes shows messages that would not be printed by the example code.)

Each iteration of the loop subtracts a positive value (called a decrement) from the loop control variable.
