Java Default Constructor Examples

  • Default constructor refers to a constructor that is automatically created by compiler in the absence of explicit constructors.
  • You can also call a constructor without parameters as default constructor because all of its class instance variables are set to default values.

Java Default Constructor Sample Code

Code:
package com.myjava.constructors;

public class MyDefaultConstructor {
    
    public MyDefaultConstructor(){
        System.out.println("I am inside default constructor...");
    }
    
    public static void main(String a[]){
        MyDefaultConstructor mdc = new MyDefaultConstructor();
    }
}

Example Output

I am inside default constructor...
