Using the Method

Here is how our new method is used by a main() program. Notice that an ArrayOps object must be created before the method can be used.

class ArrayDemo
{
  public static void main ( String[] args ) 
  {
    int[] ar1 =  { -20, 19, 1, 5, -1, 27, 19, 5 } ;

    ArrayOps operate = new ArrayOps();     // create an ArrayOps object

    int biggest = operate.findMax( ar1 );  // call findMax() with a reference to the array

    System.out.println("The maximum is: " + biggest );
  }

}      

The program defines a class called ArrayDemo.

• ArrayDemo holds the static main() method.
• main() creates an array object, ar1
• main() creates an ArrayOps object, operate.
• The findMax() method of the ArrayOps object is called with a reference to the array object ar1 as a parameter.
