Question

I am at a loss here.

I can see any reason that why the following is happening :

        public class UI extends javax.swing.JFrame {
            .
            .
            .
            .
377:        private static JDialog dialog;
378:
379:        static void conflict_dialog(){
380:        dialog =  new conflict(this, true,new File("C:\\Users\\Soumya\\Desktop\\a.sh"), 2242);
381:        dialog.setVisible(send_mode);
            .
            .

            }

        }

Uncompilable source code – non-static variable this cannot be referenced from a static context at new_file_transfer.UI.conflict_dialog(UI.java:380)

any ideas on why I am getting this error will be very helpful

Answer 1

Here’s the problem:

dialog =  new conflict(this, ...);

You’re in a static method – what do you expect this to be? It could be appropriate to construct a new UI as per thinksteep’s answer – or you may want to use an existing reference from somewhere else. It’s hard to say for sure. When you wrote that code, what did you want this to refer to?

(Note that to follow Java naming conventions, your conflict class should be renamed to Conflict; your method should probably be renamed to showConflictDialog and your send_mode variable should probably be sendMode.)
