Built-in Java Annotations: @Override example


Description:

When we use @Override annotation to a method, it let compiler know that we are overriding it from super class. It is not mandatory to use @Override when you override a method. Incase you are using @Override annotation, and the method signature is not found at super class will results compilation error.


Code:
package com.java2novice.annotations;

public class Animal {

	public void makeSound(){
		
	}
}

class Cat extends Animal{
	
	@Override
	public void makeSound(){
		System.out.println("myyyyyaaawwwwww");
	}
}

Pass by value Vs Pass by reference

Pass by reference: Passsing the address of the object, so that you can access the original object.
