loops - Resizeable Number Triangle in Java GUI -


I have this assignment for Java class which I am taking. I was assigned to do this:

Write a program that displays the numbers shown below. The number of lines in the display is changed to fit the window as the size of the window.

This is displayed in GUI (without large space between lines):

1

12

1234 P> 12345

1234567

The larger the number of the counting and the number of lines that is going up, the more I am using the GUI Expand window.

Now in my code: 

  import javax swing *. Import java.awt. *; Public class resizing GUI JPNL (public Input width = 600; public intensity height = 200; public int x_coord = 10; public int y_coord = 40; public static final int point_ size = 12; public font font object = new font ("sanssirf" Font.plain, point_size); public integer maximum number = 16; public recycling (super); setSize (width, height);} public zero color (graphics g) {superpant (h) ); G.setFont (fontObject); X_coord = 10; Y_coord = 40; Int lineCount = 0; int line = 1; MaxLines = (this.gethight () - 40) / 10; while (line count  10) {x_coord = X_coord + 5;} line = 0; lineCount ++; Y_coord = y_coord + 10;}}} public static zero main (string [] args) {JFrame frame = new JFrame (); Frame.setTitle ("Resizeable GUI") ; Frame.Set size (600,200); Frame.getContentPane (). Add (New ResizingGUI ()); Frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE); Frame.setVisible (true); }}   
 I think this solution might be, but the nested loop is throwing me for a loop (yes) if someone has suggested a way to fix the nested loop or (More likely) How to achieve your goal, I would be very grateful.   
 
 
, basically, you have lines and loops for the number columns (which is the current line number) Want a loop for the number ...  
  int line = 0; While (line & lt; maxLines) {int col = 0; While (col & lt; line) {// ... col ++; } Line ++; }   
 You are not also resetting back to  x_coord  in the initial state, which means that each new row will start at the end of the last line ... Even below this  
 You should also:  
     
  •  Override  paintComponent  instead of  Paint .  
  •  Override  getPreferredSize  instead of using  setSize  for more details. This will work better with layout managers  
  •  Use  FontMetrics  to determine how many pixels you want to adjust for each row / column Take a look for more details

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. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

java - JPA TypedQuery: Parameter value element did not match expected type -

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...
