Is it possible to extend Methods in Java?

Question

I know it is possible to do this in Java:

public class animal {...}

And then

public class dog extends animal {...}

Then you can write whatever dog methods that can access animal method.

However, I am wondering is there a way to extend methods

for example

public void generateAnimal() {...}

and then

public void generateDog() extends generateAnimal() {...}

But this is not passing the compiler. So my question is:

Is it possible to inherit methods in Java?

Answer 1

Yes.

public class Animal {
   public void someAction() {
      System.out.println("from Animal class");
   }
}

public class Dog extends Animal {
   public void someAction() {
      super.someAction();
      System.out.println("from Dog class");
   }
}

public class Main {

  public static void main(String[] args){
      Animal dog = new Dog();
      dog.someAction();
  }
}

Output:

from Animal class    
from Dog class

So you extend functionality of method, but better to use composition instead of inheritance.
