Constructor Overloading

• Concept of defining multiple constructors within the same class by changing the data types of the parameters is known as constructor overloading.

package com.instanceofjavaforus;

public class ConstructorOverloading {

int a,b,c;

ConstructorOverloading(){
    this(1);
}

ConstructorOverloading(int a){
    this(a,2);
}

ConstructorOverloading(int a, int b){
    this(a,b,3);
}

ConstructorOverloading(int a, int b,int c){
this.a=1;
this.b=2;
this.c=3;
System.out.println(a+""+b+""+c);
}
   
public static void main(String args[]){
   
    ConstructorOverloading obj=new ConstructorOverloading();
   
   }
   
}
