Different ways to overload a method in Java

JavaJava Programming Java 8

Method overloading can be achieved in following three ways −

  • By changing the number of parameters in the method.
  • By changing the order of parameter types
  • By changing the data types of the parameters.

See the example below−

Example

 Live Demo

public class Tester {
   public static void main(String args[]) {
      Tester tester = new Tester();
      System.out.println(tester.add(1, 2));
      System.out.println(tester.add(1, 2,3));
      System.out.println(tester.add(1.0f, 2,3));
      System.out.println(tester.add(1, 2.0f,3));
   }
   public int add(int a, int b) {
      return a + b;
   }
   public int add(int a, int b, int c) {
      return a + b + c;
   }
   public float add(float a, int b, int c) {
      return a + b + c;
   }
   public float add(int a, float b, int c) {
      return a + b + c;
   }
}
