Chapter 6, Problem 1P

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.
