Question

complete the JAVA code:

Next, I'd like to illustrate how inheritance works. Suppose we have an Animal class that has instance variables for height and weight, an argument constructor getters and setters, and a toString method. If we want to create Fish and Bird subclasses that contain the following information: Bird instance variable: canFly (= false for penguins) Fish instance variable needsAir (= true for whales) both argument constructor, getter, setter, toString here's what they'd look like: Bird

Explanation / Answer

public class Animal {
   double weight;
   int height;
  
   Animal(int height, double weight){
       this.height = height;
       this.weight = weight;
   }

   public double getWeight() {
       return weight;
   }

   public void setWeight(double weight) {
       this.weight = weight;
   }

   public int getHeight() {
       return height;
   }

   public void setHeight(int height) {
       this.height = height;
   }
  
   public String toString(){
       return "Weight is "+this.getWeight()+" Height is "+this.getHeight();
   }
}

public class Bird extends Animal{
   boolean canFly;
  
   Bird(int height, double weight, boolean canFly){
       super(height,weight);
       this.canFly = canFly;
   }

   public boolean isCanFly() {
       return canFly;
   }

   public void setCanFly(boolean canFly) {
       this.canFly = canFly;
   }
  
   public String toString(){
       return super.toString()+" canFly: "+this.isCanFly();
   }
}

public class Fish extends Animal{
   boolean needAir;

   public boolean isNeedAir() {
       return needAir;
   }

   public void setNeedAir(boolean needAir) {
       this.needAir = needAir;
   }
   Fish(int height, double weight, boolean needsAir){
       super(height,weight);
       this.needAir = needsAir;
   }
  
   public String toString(){
       return super.toString()+" Need Air: "+this.isNeedAir();
   }
}
