Working With Classes: Accessor, Mutator

This weeks lab involved working with 3 separate classes.  I'm excited about this lab because it worked out perfectly for me in the end and the lab itself was fun.  The goal of this project was to create a program that would ask for input for 3 different pets that included the name, weight, length, and date born  then print all of the results.  The main class referred to the pet class to set the name, weight, and length.  The pet class in turn refers to the date class to set the date of birth.

public static void main(String[] args) {



PetClass pet1 = new PetClass();
PetClass pet2 = new PetClass();
PetClass pet3 = new PetClass();


//take input referring to sub class EnterInfo in both petclass and dateclass

System.out.println("Enter your pets information");
pet1.EnterInfo();
System.out.println();

System.out.println("Enter your second pets information");
pet2.EnterInfo();
System.out.println();

System.out.println("Enter your third pets information");
pet3.EnterInfo();
System.out.println();

//printing the entered info back out

pet1.PrintInfo();
System.out.println();

pet2.PrintInfo();
System.out.println();

pet3.PrintInfo();
System.out.println();

}

It's almost like with accessors and mutators everythings backwards.  Your keyboard input goes into
the mutator which feeds into the accessor.
