Question

This program will contain 4 methods:

1) A public, static Java method called lastNumber that accepts an array of integers and returns the last element of the array.

2) A public, static Java method called join that will accept a character array as its parameter. The method should return a String that is the result of concatenating all of the characters in the array.

3) A public, static Java method called reverseArray that will accept an array of integer values and reverse the order of the array elements. The method should work with any array, regardless of the length. Do not print anything. Do not use any built-in Java “reverse” method. Do not not return a value.

4) A main method with sufficient calls to test the lastNumber, join and reverseArray methods thoroughly.
