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...

Transient and Volatile Modifiers
Transient: The transient modifier applies to variables only and it is not stored as part of its object's Persistent state. Transient variables are not serialized.

Volatile: Volatile modifier applies to variables only and it tells the compiler that the variable modified by volatile can be changed unexpectedly by other parts of the program.
Famous Quotations
The greatest obstacle to discovery is not ignorance; it is the illusion of knowledge.
