java - draw method animation to another class -


There is a bit thicker with Java, but someone can tell me how to take the draw method from the list of objects, from where There is more 1 box, and it has to be put into action, so I redesign X and y to and move them Can I modify the getter?

to box class: 

  public zero draw (graphics g) {g.setColor (Color.BLUE); Gifilact (getX) - (width / 2)), (getY) - (height / 2)), getWidth (), getHeight ()); }   
  actionPerform  method: (this is in another class)  
  PublicExchangeEvent (e) {timer. Start (); }    
 
 
 The basic idea is ...  
 when  Actions are called  ...  
     
  •  Repeat through the list of objects and update them in something meaningful  
  •  Re-create the call.   
     Then  paintComponent  method within your components, repeat the list and color them  
     The following is a very basic concept. ..  
     box  
      Import java.awt.borderLayout; Import java.awt.color; Import java.awt.Dimension; Import java.awt.EventQueue; Import java.awt.Graphics; Import java.awt.Graphics2D; Import java.awt.event.ActionEvent; Import java.awt.event.ActionListener; Import java.util.ArrayList; Import java.util.list; Import javax.swing.JComponent; Import javax.swing.JFrame; Import javax.swing.JPanel; Import javax.swing.Timer; Import javax.swing.UIManager; Import javax.swing.UnsupportedLookAndFeelException; Public class flyingbox {public static zero main (string [] args) {new flying box (); } Public Interface Drawable {Public Zero Update (JComponent Comp); Public Zero Draw (Graphics G); } Public square box applies Drawable {Private int x; Private int y; Private int width = 10; Private intensity height = 10; Private Int x Delta; Private int yDelta; Public box (int x, int y) {this.x = x; this. Y = y; XDelta = random (); YDelta = Random (); } @ Override Public Recording Update (JCMPnet Comp) {x + = xDelta; Y + = yDelta; If (x <0) {x = 0; XDelta * = -1; } And if (x + width> comp.getWidth ()) {x = comp.getWidth () - width; XDelta * = -1; } If (Y end lie; 0) {y = 0; YDelta * = -1; } And if (y + height> comp.getHyight ()) {y = comp.getHeight () - height; YDelta * = -1; }} @ Override Public Empty Draw (Graphics G) {g.setColor (Color.BLUE); G.fillRect (X, Y, width, height); } Secure Sur Random () {int value = 0; Do {value = -2 + (int) (Math.random () * 4); } While (value == 0); return value; }} Public Flying Box () {EventQueue.invokeLater {@Override Public Zero () {{UIManager.setLookAndFeel (UIManager.getSystemLookAndFeelClassName ())}} Catch (ClassNotFoundException | InstantiationException | Invalid Access Exception | unsupported view and before fxx expansion) {} Jeffre Frame = New Gefram ("Test"); Frame.Set default close operation (JFRM.EXIT_ON_CLOSE), frame.selectable (new border layout ()); Frame.ed (new testpan ()); Frame.pack (); Frame.Setlineschillate (faucet); Frames.Seviable (true);}}); } Public Square TestPane JPanel {Private listing & lt; Drawable & gt; Drauble; {Int x = (int) (Math.Rendem) for public testpane () (droble = new arrelistist <; (25); (int index = 0; index; * 190); Int y = (int) (Math.random (* * 190); Drawables.add (new box (x, y)); timer timer = new timer (40, new exclamation engineer) ({override public void Action Criteria (Draft D: Drabs) {d.update (TestPane.this)}} repaint ();}}); timer.start ();} @ Override public dimension getPreferredSize () { New Dimension Back (200, 200);} @ Override Protected Zero Do Tkanpanent (Graphics g) to {Suprpintkanponent (g); (Drayniy D: Drobl) {Dkdraw (G);}}}} On

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...

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...
