Java Parameterized Constructor Examples

  • Parameterized constructors are required to pass parameters on creation of objects.
  • If we define only parameterized constructors, then we cannot create an object with default constructor. This is because compiler will not create default constructor. You need to create default constructor explicitly.

Java Parameterized Constructor Sample Code

Code:
package com.myjava.constructors;

public class MyParameterizedConstructor {
    
    private String name;
    
    public MyParameterizedConstructor(String str){
        this.name = str;
        System.out.println("I am inside parameterized constructor.");
        System.out.println("The parameter value is: "+str);
    }
    
    public static void main(String a[]){
        MyParameterizedConstructor mpc = new MyParameterizedConstructor("Madhu Raj");
    }
}

Example Output

I am inside parameterized constructor.
The parameter value is: Madhu Raj

What is OOPs?
Object oriented programming organizes a program around its data, i.e. , objects and a set of well defined interfaces to that data. An object-oriented program can be characterized as data controlling access to code.
