📌 What is Polymorphism?

Polymorphism means "one name, many forms". In Java, it allows methods to behave differently based on input or object.

🔹 Method Overloading

Method Overloading means having multiple methods with the same name but different parameters.

class Demo {
  void add(int a, int b) {
    System.out.println(a + b);
  }

  void add(int a, int b, int c) {
    System.out.println(a + b + c);
  }
}

🔹 Method Overriding

Method Overriding means redefining a method in a child class.

class Parent {
  void show() {
    System.out.println("Parent class");
  }
}

class Child extends Parent {
  void show() {
    System.out.println("Child class");
  }
}
