//  This program works in the same way as LargestWithReturn.java.
//  In this version an array whose length is 1 is used to transfer
//  an int value from the called method to the caller.
//  This is not necessarily a nice way to use arrays.
//  The purpose of this program is to show how arrays behave as
//  method parameters.
