Modify the definition of the class Species in Listing 5.19 of Chapter 5 by removing the method setSpecies and adding the following methods:
• Five constructors: one for each instance variable, one with three parameters for the three instance variables, and a default constructor. Be sure that each constructor sets all of the instance variables. • Four methods named set that can reset values: one is the same as the method setSpecies in Listing 5.16, and the other three each reset one of the instance variables. Then write a test program to test all the methods you have added. Finally, repeat Practice Program 1 in Chapter 5, but be sure to use some constructor other than the default constructor when you define new objects of the class Species. This project requires the development of test cases that exercise each of the new constructors and methods at least once.
