The UI class that will call the methods in the manager class

/*

 */
package inheritance;

public class DogsUI {

    public static void main(String[] args) {
        DogManager dm = new DogManager();

        System.out.println("Hello Dogs");
        System.out.println(text);

The Manager class where we will place all our methods

/*
 * Dog Manager with methods to create object arrays
 * This will include reading in the text file
 */
package inheritance;

public class DogManager {
    // global variables including arrays
    private Dogs[] dogs = new Dogs[20];
    private int size = 0;
    
    DogManager() {
        System.out.println("Dog Manager");

The Dog class - the super class

/*

 */
package inheritance;

public class Dogs {
    String name = "Dog";
    int age = 0;
    boolean pedigree = false;
    
public String toString() {
    
    return name + "\t" + age + "\t" + pedigree;
}
}
==================================================================
The Working class - the sub class to Dog

/*
 * Extends the dog class
 */
package inheritance;

public class WorkingDog extends Dogs{
    // Working dog has an additional field
    String trainer = "Nil";

public String toString() {
	// returns Dog toString with the extra field
    return super.toString() + "\t" + trainer;
}
}
