Java Constructor Overloading Examples

Like method overloading we can overload constructors also. Along with default constructor, we can have constructors with parameters. The no of parameters can be same, and it can have different datatypes. Below example gives sample code for constructors overloading.

Java Constructor Overloading Sample Code

Code:
package com.myjava.constructors;

public class MyOverloading {
    
    public MyOverloading(){
        System.out.println("Inside default constructor");
    }
    public MyOverloading(int i){
        System.out.println("Inside single parameter constructor with int value");
    }
    public MyOverloading(String str){
        System.out.println("Inside single parameter constructor with String object");
    }
    public MyOverloading(int i, int j){
        System.out.println("Inside double parameter constructor");
    }
    
    public static void main(String a[]){
        MyOverloading mco = new MyOverloading();
        MyOverloading spmco = new MyOverloading(10);
        MyOverloading dpmco = new MyOverloading(10,20);
	MyOverloading dpmco = new MyOverloading("java2novice");
    }
}

Example Output

Inside default constructor
Inside single parameter constructor with int value
Inside double parameter constructor
Inside single parameter constructor with String object
