swing - Contentpanes not working in java -


I can reply early tomorrow (I'm really tired)

did this Was:

This line of code is giving me an error: 

  win1.getContentPane (). Add (empty label, BorderLayout.CENTER);   
 I have problems with this part:  
  Empty label   
 This throws an error and it To change win1, which does not show an error, but throws it  
 Full class:  
  package examplepackage; // import import java.awt.borderLayout; Import javax.swing.ImageIcon; Import javax.swing.JFrame; Import examplepackage.location.GetFilepath; Public category starter {public static zero main (string [] args) {GetFilepath FP = New GetFilepath (); Jeffram Win 1 = New Jeffram ("Example Window"); win1.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE); Win1.getContentPane (). Add (empty label, BorderLayout.CENTER); Win1.pack (); Win1.setSize (600, 800); Win1.setVisible (true); Win1.setLocationRelativeTo (win1); win1.setIconImage (new IMP (FP + "\\ window \\ main"). getImage ()); }}    
 
 
 Then, by example,  GetFilePath  , Because I do not have access to that source when I compile my code. I ...  
  Error: The symbol can not get win1.getContentPane (). Add (emptyLabel, Border Layout, CA); ^ Symbol: Variable blank label space: class starter   
 originally defined as  empty label . It is possible that your IDE is looking for a matching value that can be sent to the law parameter, again depending on the code, which leaves  win1 , which clearly works (You can add something in your own or add a  window  based component to  container )  
 What you need to do and Make an example of some component, such as  JLabel , for example ...  
  JLabel empty label = new j Alab (); Win1.getContentPane (). Add (empty label, BorderLayout.CENTER);   
 I also suggest that you have read and make sure that you are starting your UI in the context of the event dispatching thread

I know that this is not beautiful, but I am very naive and for some reasons I know from using arrays, anyway, my problem is that I can not add a variable outside the listener and within the action listener I can modify the variable (pTurn ++) from How can I go about adding a count to that variable from inside the action listener? 1 error was found: file: c: \ user \ public \ togiz_kumalak.java [line: 130] error: local variables pTurn is accessed from within internal class; Need to be declared final int pTurn = 0; Button1.addActionListener {new zero-action action (action event e) {pTurn ++; if (pTurn% 2 == 0) {display.append ("\ n Player 2 cup 1");} If ( PTurn% 2! = 0) {display.append ("\ nPlayer 1Cup 1")}}); In that case, move the contents of the functionalities into orbit and then call the action For example, display the method from: Private Zero Button Press {pTurn ++; If (pTurn% 2...
