{'c', 'o', 'c', 'o', 'N', 'U', 'T'}	{'C', 'O', 'C', 'O', 'n', 'u', 't'}
{'S', 't', 'U', 'd', 'E', 'n', 'T'}	{'s', 'T', 'u', 'D', 'e', 'N', 't'}

    {
        char[] inputArray = {'a', 'Y', 'U', 'r', 'v', 'E', 'D', 'A', 'M'};
        char[] outputArray = convertToAnotherCase(inputArray);
        System.out.print("The character array is " );
        for(int i = 0; i < outputArray.length; i++ )
        {
            System.out.print(outputArray[i] + ", ");
