Method Overloading in Java - Compile-time Polymorphism

Method Overloading

If a class has multiple methods having same name but different in parameters, it is known as Method Overloading.

Ways to overload:

By changing number of arguments.

By changing the data type.

class Adder {
  static int add(int a, int b) {
     return a + b;
  }
  static double add(double a, double b) {
     return a + b;
  }
}
class TestOverloading {
  public static void main(String[] args) {
    System.out.println(Adder.add(11, 11));
    System.out.println(Adder.add(12.3, 12.6));
  }
}
