What is @Override Annotation in Java Programming

@Override Annotation in Java Programming

Hello Guys! I'm 101Programmer, In this post, You going to see What is @Override Annotation in Java Programming.

@Override Annotation is used when we override a method in the Sub-class. Generally, novice Developers overlook this feature as it is not mandatory to use this annotation while overriding the method in Java. Below I gave an example for this @Override Annotation.

Example:

class ParentClass { public void displayMethod(String msg){ System.out.println(msg); } } class SubClass extends ParentClass { @Override public void displayMethod(String msg){ System.out.println("Message is: "+ msg); } public static void main(String args[]){ SubClass obj = new SubClass(); obj.displayMethod("Hey!!"); } }


In the above example, we are overriding a method displayMethod() in the child class. Even If we dont use the @Override Annotation, the program would still run fine without any error.
