A little help in AWT.. (reading a textfield from another class)

Question

I got this Panel with a varying number of TextFields (to input a matrix).
so i did (in the Panel sub-class)
TextField Determinant[] = new TextField[l*l];
          for (int i = 0; i < l*l; i++)
               add(Determinant[i] = new TextField(""+i));
then i want to read them into a 2 dimensional array after pressing a button (in the Button subclass)
for (int i = 0; i < det.length; i++)
               for (int j = 0; j < det.length; j++)
                    det[i][j] = (double)Panel1.Determinant[k].getText();
                    k += 1;
but then the compiler complains:
C:\java projects\GoButton.java:30: cannot resolve symbol
symbol : variable Panel1
location: class GoButton
det[i][j] = (double)Panel1.Determinant[k].getText();
how do i get the Button-subclass to "know" the Textfields in the Panel subclass?
(they're both public)
help please! :)

Answer 1

Is "Panel1" a class name or a variable or field name?
If the latter, you ought to use Java naming conventions: only class names and constants start with upper-case letters. So "Determinant" in your code is also poorly named.
Also I'd strong advise against using "l" (a single lower-case ell) as an identifier. It's really hard to read.
Also when you post code, please wrap it in &#91;code]&#91;/code] tags, so we can read it.
Assuming that "Panel1" is a field or variable -- then you need to either make it accessible by the other classes that need to access it, or better yet pass its value as an argument to those things that need it.
Or maybe restructure your code so that the things that need to use it are in the same class as Panel1, possibly as member classes.
