Java Overloading Constructor

In this Java Program, easy to understand Overloading Constructor concept in Java.

Introduction

In this blog I will explain about Overloading Constructor in Java. It is very simple in Java Programming. The output will be displayed in the Run module.

Software Requirement

JDK1.3

Simple program

class overlo                         // overlo is a class name
 {
   double x,y;

   overlo(double a, double b)       // overlo is parameterized constructor
    {
     x = a;
     y = b;
    }

   public void squ()                // squ() is method name
    {
      System.out.println("The Area of Square : "+(x*x));
    }

   public void rec()                // rec() is method name
    {
      System.out.println("The Area of Rectangle : "+(x*y));
    }

   public void cir()                // cir() is method
    {
      System.out.println("The Area of Circle : "+(3.14*x*x));
    }

   public static void main(String arg[])
    {
      overlo t;

      t = new overlo(4,4);          // overloading constructor
      t.squ();

      t = new overlo(5,6);         // overloading constructor
      t.rec();

      t = new overlo(2,3);          // overloading constructor
      t.cir();
    }
 }
