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

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
