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");
	}
}

Exception Vs Error
An error is an irrecoverable condition occurring at runtime like out of memory error. These kind of jvm errors cannot be handled at runtime. Exceptions are because of condition failures, which can be handled easily at runtime.
Famous Quotations
The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails.
