Java for Programmers: Lab 9

Create 2 subclasses of animal, a Dog and a Cat. They do not need any methods or data of their own yet. They should suppply a constructor that passes an appropriate genus and species to the superclass [Animal] constructor.

Create a new class called AnimalRunner which has a main method. In the main method of AnimalRunner, you should create a new Array of Animal type. Add 3 elements to it: a Cat, a Dog and a Person.

Iterate through the array and print out the genus and species of each animal.

public class Dog extends Animal {

    public Dog() {

     super("canis", "familiaris");

    }

  }

                  

                  
package com.annedirkse;
                  
                  
public class Cat extends Animal {

    public Cat() {
 
      super("felis", "domesticus");

    }

}

                    
package com.annedirkse;

public class Person extends Animal {
  private String name;
  private int age;
  private int hairColor;

  static final int HAIR_COLOR_BROWN = 1;
  static final int HAIR_COLOR_BLONDE= 2;
  static final int HAIR_COLOR_RED = 3;
  static final int HAIR_COLOR_BLACK = 4;
  static final int HAIR_COLOR_GRAY = 5;
 public void setHairColor(int hairColor) {
   this.hairColor = hairColor;
  }
 public int getHairColor() {
   return hairColor;
  }
 
 public void setAge(int age) {
   this.age = age;
  }
 
 public void setAge(String age) {
   Integer ageInt = new Integer(age);
   this.age = ageInt.intValue();
  }
 
 public void setName(String name) {
   this.name = name;
  }
 public String getName() {
   return name;
  }
 public int getAge() {
   return age;
  }
 public Person(String name) {
   super("homo", "sapiens");
   this.name = name;
  }

}

      System.out.println(animal.getSpecies());
