[saikrishna cinux]

Hi,
When will be final fields get loaded?
and what are the advantages of being final varaibles and eing final static variable?

thanks,
Sai

[saikrishna cinux]

   
public class Test {
final int i;
private Test(final int x){i=x;}

public static void main(String[] args) {

Test t1=new Test(1);
Test t2=new Test(2);
Test t3=new Test(3);

System.out.println(t1.i);
System.out.println(t2.i);
System.out.println(t3.i); 
}
}

Is it a right way to declare final where ever i used in thi program?

But, is there any need to specify the parameter of constructor as final???
I think no...

Some folks believe it makes sense to declare all parameters as final. Modifying the parameters of a method can lead to confusing code, and marking them as final prevents that.

Hi Friedman-Hill

Modifying the parameters of a method can lead to confusing code, and marking them as final prevents that.

I couldn't get the meaning of that. Could you please explain that concept?

As far as i can think, EFH means that people do believe that declaring parameters as final do help, because the parameter cannot be modified and thus prevents erroneous code.
