Method Overriding?

July 15 2026

What is Method Overriding?

Method Overriding is an Object-Oriented Programming (OOP) feature where a child class provides its own implementation of a method that already exists in the parent class.

Parent class

Child class

Output:

---

Child class (use super key)

Output:

---

What is the super Keyword in Java?

• The super keyword is used to refer to the parent (superclass) object from a child class.

• It allows a child class to access the parent class's methods, variables, and constructors.

• Buy public class Child extends Parent Parent object works, but the Child value no longer runs,
  -created Child object works in parent and child

---

Key Points

Same method name.
Same parameters.
The parent class method is redefined in the child class.
The child class method is executed when called on a child object.

---

Simple Errors

Variable Error

Why Does This Happen?

In Java, each local variable must have a unique name within the same method.

Here, the variable buy is declared twice.
