Method Overriding :

If the child class has the same method declared as in the parent class,known as “Method Overriding”.
Example :-

class Teacher{
public void work() {

System.out.println("Teaching");
}
}

class Student extends Teacher{
public void work(){

System.out.println("Learning");

}

public static void main( String args[]) {

Student s = new Student();
s.work();

}
}

Output :-

Learning

Here work() is overridden method declared in both Teacher and Student class.

• points of Method overriding :-
• It is used to provide specific execution of a inherited method without modifying the parent class.
• It is used to achieve Run time polymorphism.

Points to remember :-
*  We can not override static method because static method is bound with class.
*  We can not override private,final methods too.
*  We can not override main method because of static method.
*  It is different from overloading , where parameters must be different in overloading but not in case of overriding.
