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

Knowledge Centre
Purpose of garbage collection
The garbage collection process is to identify the objects which are no longer referenced or needed by a program so that their resources can be reclaimed and reused. These identified objects will be discarded.
Famous Quotations
If you don’t make mistakes, you’re not working on hard enough problems. And that’s a big mistake.
