Repeat Programming Project 2 in Chapter 5. This time, add the following four constructor methods: one for each instance variable, one with two parameters for the two instance variables, and a default constructor. Be sure that each constructor sets all of the instance variables. Write a driver program to test each of the methods, including each of the four constructors and at least one true and one false case for each of the test methods.
The solution to this project sets the name parameter to “No name” and age to 0 if they are not specified in the constructor. In addition, if the age argument is a negative number an error message is printed and the age is set to 0.
