How to call super class constructor from subclass constructor?

Submitted by Bharat on Sat, 09/04/2010 - 00:15

Constructor of the super class can be called using super.

public class Q1 {
 Q1(){
  System.out.println("Default Construcotr");
 }
 
 Q1(String msg){
  this(); //calls default constructor
  System.out.println("One Argument Constructor");
 }
}
 
class Q2 extends Q1{
 
 Q2(){
  super();//calls no default constructor of Q1 class.
  
  /*
   * To call super class constructor with arguments, pass same arguments in
   * super.
   *
   * e.g.
   * super("Hello world") will call Q1(String msg) constructor.
   */
 }
}
