compilation error

[joshua antony]

 class SuperClass{
 
public SuperClass(int x)
{}
}
public class SubClass extends SuperClass{
 
public SubClass ()
{
super(x);//compilation error here!
System.out.println("constructor");
 
}
int x =Method();
{
System.out.println("value of x is "+x);
}
public int Method()
{
System.out.println("int method");
return 5;
}
 
public static void main(String[] args)
{
new SubClass();
}
}

I get a compilation error stating
cannot reference x before supertype constructor has been called..
Do i get this error just because it is specified in the JLS that instance variables cannot be referenced in constructor before call to super?

I am not able to understand this, because any way x is initialised to 5 before we make a call to super constructor.
Am I missing something silly..

The superclass will be initialized before the subclass. If x were to be resolved to 5 and sent to the constructor of the superclass, then the subclass would have to be initialized before the superclass.

Are you talking about the code from Joshua?

Can you post the changes you made to it?

It sounds like you had a problem with either the command line or CLASSPATH.

Hi Keith,
I am sorry for my last post actually yesterday I downloaded the enthuware database so for that I made some changes in my classpath and I forgot to include the current directory in it. So, that's why it was giving error...Sorry for your inconvenience

Everything is working fine now...including Joshua's code

again thanks's alot for your help...


regards
Swapnil
