Modify the NumbersDemo application whose main() method holds two integer variables.

Assign values to the variables.

In turn, pass each value to methods named displayTwiceTheNumber(), displayNumberPlusFive(), and displayNumberSquared().

Create each method to perform the task its name implies.

The output is shown below:

4 times 2 is 8

4 plus 5 is 9

4 squared is 16

33 times 2 is 66

33 plus 5 is 38

33 squared is 1089
