Problem with constructor overloading

[Andreex]

I have this code


class sobre {


sobre (int x)
{
System.out.println(x);
}

sobre (int x, int y)
{
sobre(x);
}

public static void main(String arguments[])
{
sobre s=new sobre(3,21);
}

}


Wich is overloading the constructor... but it tells me C:\Program Files\Xinox Software\JCreator Pro\MyProjects\aaa\sobre.java:12: cannot resolve symbol
symbol : method sobre (int)
location: class sobre
sobre(x);


WHY!!! It should work!!!

try this...

class sobre { 


sobre (int x) 
{ 
    System.out.println(x); 
} 

sobre (int x, int y) 
{ 
    this(x); 
} 

public static void main(String arguments[]) 
{ 
    sobre s=new sobre(3,21); 
} 

}

Andreex somthing things you might want to
take note of. The this() construct when
used in this manner is called a "constructor call
statement" Using this() in this manner enables
local chaining of constructors. Java places restrictions
on how it is to be used. For instance this can only be
used in a constructor definition. Also this() must appear
as the first statment in a constructor.

Using super() allows your subclass to
influence the intialization of it's inherited state when
an object of the subclass is created. Some of the same
restrictions apply. super() can only appear as the
first statement in a constructor. So basically this()
and super()cannot occur in the same constructor.

class Light {
     private int watts;
     private boolean indicator;
     
    Light(){
      this(300,false);
      System.out.println("Returning from non-default constructor 1 in class Light");
       }

    Light(int watts, boolean indicator){    
      super(); // implicitly placed in if not supplied 
       this.watts = watts;
        this.indicator = indicator; 
       System.out.println("Returning from non-default constructor 2 in class Light");
       } 
}
   class HighPressureSodiumLamp extends Light{
      
    private int heatDisplacement;
 
   HighPressureSodiumLamp(){
     this(600,300,false);
      System.out.println("Returning from non-default constructor 1 in class HighPressureSodiumLamp");
      }
   
    HighPressureSodiumLamp(int heatDisplacment,int watts, boolean indicator){
    super(300,false);
       this.heatDisplacement = heatDisplacment;
         System.out.println("Returning from non-default constructor 2 in class HighPressureSodiumLamp");
      }
   }

 class Test{
   public static void main(String[] args){
 	   HighPressureSodiumLamp hps = new HighPressureSodiumLamp();
   } 
 }

So... the code up here.... wouldnt work????

That's very intereseting,,,, thanks for the note!

[Andreex]

Humm..... I did something similar and it did work....

[Dillinger4]

The code that you posted with the change made by crypt would work. My code should compile also.

[Andreex]

?????? what was that?!!?

[Andreex]

?????? THAT IS WIERD!!!

A MESSAGE IN MY MSN MESSEANGER CAME UP I HAD A NEW EMAIL FORM VBWORLD AND I CAME IN THRU THE LINK... IT BROUGHT ME TO THIS POST... AND YOU (DILIGENT) POSTED A PIC OF A MAGIC LAMP... BUT.. NOW I CAME DIRECTLY TO VBFORUMS AND THAT POST (YOURS) IS GONE... HOW CAN YOU DO THAT?!
