New Picture

Here a picture that shows the situation just after the second method call: operate.print( ar2 ); The parameter x of the method now refers to the second array.

By using parameters with methods you can use the same method with different data. This makes the method into a useful tool that can be used in many situations.

Note: In this picture, the arrow connected to ar2 and the arrow connected to x look quite different, although they point to the same object. However, when the program is running, the reference in x is identical to the reference in ar2. Both contain an identical reference to the array object.
