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

Knowledge Centre
true and false are keywords?
true, false, and null might seem like keywords, but they are actually literals. You cannot use them as identifiers in your programs.
