Difference between “this” and“super” keywords in Java

Question

What is the difference between this and super keywords in Java?

Answer 1

Consider this code:
 

class Animal {

  void eat() {

    System.out.println("animal : eat");

  }

}

class Dog extends Animal {

  void eat() {

    System.out.println("dog : eat");

  }

  void anotherEat() {

    super.eat();

  }

}

public class Test {

  public static void main(String[] args) {

    Animal a = new Animal();

    a.eat();

    Dog d = new Dog();

    d.eat();

    d.anotherEat();

  }

}

The output is:

animal : eat

dog : eat

animal : eat

The third line is printing animal : eat because we are using super, if we have used this it would have printed dog : eat
