The field "name" doesnt apparently exsist :/

This code:

Code:

---

try {
                                f.getClass().getField(txt).set(txt,real.substring(0,i));
                        } catch (Exception e) {
                                e.printStackTrace();
                        }

---

Gives this error:

Code:

---

Can not set java.lang.String field Window.name to java.lang.String

---

Ehh wut?!

Why cant it assign a string, to a string object?

Because you dont read the API Doc *g*
--> Field.set

Parameters:
obj - the object whose field should be modified
value - the new value for the field of obj being modified

try: set(f,real.substring(0,i));

You are referencing an incorrect object 'txt' in your getField( ... ) method; it should refer to the object to which you want to set its field. b.t.w. why are you using reflection?

kind regards,

Ahhh okeee!!! :D
I did read it, tho I didnt understand what they ment with object
so I thought they ment object type like String and int etc :P

Well, now I sorta fixed it, the window I belive, is a copy of the real..
Because the window name doesnt change in any of the open windows, only in the one called this.f

Heres a lil bit of my code:

Code:

---

public class AnimationManager {
       
        public static void text(Window f, String txt,String real,int time){
                new Thread(new writeString(f).start();
        }

       
}

class writeString implements Runnable{

        Window f;
       
        public writeString(Window f){
                this.f = f;
               
        }
       
        private static void wait(int time){
                try{
                        Thread.sleep(time);
                } catch(Exception e){}
        }

        @Override
        public void run(){
            changing f here wouldnt change the f that we got in the text method right?
If so, how can I change the text methods f from this method?
                }
        }

Myself, I still am finding it hard to see what you're trying to do, but I also agree with the others that reflection doesn't smell right here. Consider creating and posting a small runnable version of your problem, an SSCCE.

Well, my main idea is to have a method
that I can call that would run in an extra thread, thus not
hogging up the maincore.

What I want it to do is to change values in a class instance called
Window.

Window "f" have the parameter-String "name"

So I want to call a method text(f.name,"awsome",4000);
Using that simple method, it would add a character, one at a time
until f.name = "awsome"
This should also only take 4000 miliseconds.

That's what I want to do, and probebly I overcomplecated things eyy? :P

lawls!
Had forgot to update the repaint in the while loop :P
So the actualy picture never updated :P
