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...

Difference between while and do-while
The while statement verifies the condition before entering into the loop to see whether the next loop iteration should occur or not. The do-while statement executes the first iteration without checking the condition, it verifies the condition after finishing each iteration. The do-while statement will always execute the body of a loop at least once.
Famous Quotations
You can never get enough of what you don’t really need.
