Java Multiple Inheritance

Question

In an attempt to fully understand how to solve Java\'s multiple inheritance problems I have a classic question that I need clarified.

Lets say I have class Ani

Answer 1

Ehm, your class can be the subclass for only 1 other, but still, you can have as many interfaces implemented, as you wish.

A Pegasus is in fact a horse (it is a special case of a horse), which is able to fly (which is the "skill" of this special horse). From the other hand, you can say, the Pegasus is a bird, which can walk, and is 4legged - it all depends, how it is easier for you to write the code.

Like in your case you can say:

abstract class Animal {
   private Integer hp = 0; 
   public void eat() { 
      hp++; 
   }
}
interface AirCompatible { 
   public void fly(); 
}
class Bird extends Animal implements AirCompatible { 
   @Override
   public void fly() {  
       //Do something useful
   }
} 
class Horse extends Animal {
   @Override
   public void eat() { 
      hp+=2; 
   }

}
class Pegasus extends Horse implements AirCompatible {
   //now every time when your Pegasus eats, will receive +2 hp  
   @Override
   public void fly() {  
       //Do something useful
   }
}
