everyone can help me..?
I'm very confuse..

hmm.. How write two overload methods that return the average of an array. for example with the following headers:
public static int average (int [] array);
public static double average (double [] array);

Thank you so much......

You simply write two functions with the same names but different return types and/or argument lists. The prototypes you have presented have that quality so those are the prototypes of overloaded functions. You will have to write the body of each function to be different so that the first handles an array of integers and the second handles an array of doubles.

you already are. different parameters will automatically override the method.

Title renamed to be more descriptive of the problem.

I think you might mean overloading methods, not overriding methods.

@OP: You simply have to define the bodies of the functions. However, overloading methods is basically using different methods with the same name and a different number, type or order of arguments/parameters. Java does not look at return-type when considering overloaded methods.

Also, just a suggestion, I would change the return-type of your average(int[] array) to a double instead of an int because if the sum < array.length, it will return 0 (hint- you should probably also store the sum variable as a double).

I've attached the link to the Sun tutorial on Defining Methods: http://java.sun.com/...OO/methods.html

Hope this helps clear up overloading methods. Good luck!
