Java Program to Implement Constructor Overloading

by

Aim:

To write a Java program to implement constructor overloading.

Program:

class A
{
int l,b;
A()
{
l=10;
b=20;
}
A(int u,int v)
{
l=u;
b=v;
}
int area()
{
return l*b;
}
}
class overconstructdemo
{
public static void main(String args[])
{
A a1=new A();
int r1=a1.area();
System.out.println("The area is: "+r1);
A a2=new A(30,40);
int r2=a2.area();
System.out.println("The area is: "+r2);
}
}

Output:

The area is: 200
The area is: 1200
