Exercise 8-1. Write a program with an overloaded method for tripling the value of the argument. You don’t need to create a separate class for this; just use static methods right in Tester. One version of the method should triple an int value, and the other version should triple a float value. Call both methods to demonstrate that they work.

Exercise 8-2. Create a Dog class, where the Dog objects have both a weight and a color, hidden from the client. Create a Dog object, then retrieve its color and display it to the user. Ask the user for a weight, and use that input to set the Dog’s weight.

Exercise 8-3. Write a program with just one method that takes an int value, supplied by the user, and returns both double and triple that value. You don’t need a separate class; just put the method in Tester. In Run( ), output the results to the console to make sure it worked.

Exercise 8-4. Modify the program from Exercise 8-3 so that you don’t need to initialize the variables that will hold the doubled and tripled values before calling the method.
