Difference between super() and this() in Java

Following are the notable differences between super() and this() methods in Java.

Example

 Live Demo

class Animal {
   String name;
   Animal(String name) {
      this.name = name;
   }
   public void move() {
      System.out.println("Animals can move");
   }
   public void show() {
      System.out.println(name);
   }
}
class Dog extends Animal {
   Dog() {
      //Using this to call current class constructor
      this("Test");
   }
   Dog(String name) {
      //Using super to invoke parent constructor
      super(name);
   }
   public void move() {
      // invokes the super class method
      super.move();
      System.out.println("Dogs can walk and run");
   }
}
public class Tester {
   public static void main(String args[]) {
      // Animal reference but Dog object
      Animal b = new Dog("Tiger");
      b.show();
      // runs the method in Dog class
      b.move();
   }
}

Output

Tiger
Animals can move
Dogs can walk and run
