別のパネルのswitch文を使用するにはどうすればよいですか？

Question

私は本質的には一種のスロットマシンであるクラスのプロジェクトに取り組んでいます。上に3つの列があり、ユーザーがボタンをクリックして上のパネルの形を変更できるようにしました。ボトムには実際のスロットマシンがあり、目的はスピンした後に「スロットマシン」が何を表示するかを試してみることです。私はパネルとswitch文を書いていますが、ユーザーが上部で変更しなければならないパネルの形状を変更するのに問題があります。誰でもこのことについてどうやって正しい方向に私を置くことができますか？

これはボタンとそのアクションを作成するパネルです：

import java.util.*;

public class SlotPanel extends JPanel { 
ImagePanel slotOne, slotTwo, slotThree; // three panels for the computer to

       break; 
       case 3: 
        currentShape = 0; 
       break; 
      } 
      } 
     } 
    } 
} 

// ActionListener class to determine when the Spin button is called 

public class Spin implements ActionListener{ 

    public void actionPerformed(ActionEvent event){ 
    Random generator = new Random(); 

     //Changes the background color to green if all of the wheels match 
     //or red if even one does not match to its designated wheel 
     if (slotOne == userOne && slotTwo == userTwo && slotThree == userThree) 
      setBackgroundColor(Color.green); 
     else 
      setBackgroundColor(Color.red); 


    } 
    } 
} 

そして、これが変更されているパネルを作成し、私が作った画像パネルである：

import java.awt.*; 
import javax.swing.*; 

// This class describes each of the Image Panels (6 total displayed) 
// And provides methods for drawing of the shapes 
public class ImagePanel extends JPanel{ 
// Use an int value to keep the current shape for the object 
private int currentShape, count; 
// Constructs the panels by assigning their shape and size 
public ImagePanel() { 
setPreferredSize(new Dimension(110,100)); 
setBackground(Color.black); 
currentShape = 0; 

} 

// Redraws the object after "Spin" has been selected 
public void changeShape(){ 
    currentShape++; 
    if (currentShape > 3) 
     currentShape = 0; 

    // Repaint is called 
    repaint(); 
} 

// Used when the "SpinMachine" button is called to randomly generate shapes 
public void changeShape(int setShape){ 
    currentShape=setShape; 
    repaint(); 
} 

// Accessor for the shape 
public int getShape(){ 
    return currentShape; 
} 

// PaintComponent method takes care of the drawing 
public void paintComponent(Graphics g){ 

    super.paintComponent(g); 
    g.setColor(Color.blue); 

//Switch method to change between the four shapes needed for the slot machine 
    switch (currentShape) { 
    case 0: g.fillRect(25, 20, 35, 70); 
    break; 
    case 1: 
     g.fillOval(25, 20, 70, 70);

ここではコードの作業バージョンを示していますが、以下で間違っていたことを説明しています。テスト目的で私自身のメインメソッドを追加しました。まず

import java.awt.*; 
import javax.swing.*; 

// This class describes each of the Image Panels (6 total displayed) 
// And provides methods for drawing of the shapes 
public class ImagePanel extends JPanel{ 
// Use an int value to keep the current shape for the object 
private int count; 
private int currentShape; 
// Constructs the panels by assigning their shape and size 
public ImagePanel() { 
setPreferredSize(new Dimension(110,100)); 
setBackground(Color.black); 
currentShape = 0; 

} 
public void incrementCurrent(){ 
    currentShape++; 
    if(currentShape>3) 
     currentShape=0; 
    changeShape(currentShape); 
} 
// Redraws the object after "Spin" has been selected 
public void changeShape(){ 
    currentShape++; 
    if (currentShape > 3) 
     currentShape = 0; 

    // Repaint is called 
    repaint(); 
} 

// Used when the "SpinMachine" button is called to randomly generate shapes 
public void changeShape(int setShape){ 
    currentShape=setShape; 
    repaint(); 
} 

// Accessor for the shape 
public int getShape(){ 
    return currentShape; 
} 

// PaintComponent method takes care of the drawing 
public void paintComponent(Graphics g){ 

    super.paintComponent(g); 
    g.setColor(Color.blue); 

//Switch method to change between the four shapes needed for the slot machine 
    switch (currentShape) { 
    case 0: g.fillRect(25, 20, 35, 70); 
    break; 
    case 1: 
     g.fillOval(25, 20, 70, 70); 
     break; 
    case 2: 
     int x[]={55,15,95}, y[]={25,95,95}; 
     g.fillPolygon(x,y,3); 
     break; 
    case 3: 
     g.fillRect(25, 25, 70, 35); 
     break; 
    default: 
     break; 
    } 
    } 
}

     //or red if even one does not match to its designated wheel 
     if (slotOne == userOne && slotTwo == userTwo && slotThree == userThree) 
      setBackgroundColor(Color.green); 
     else 
      setBackgroundColor(Color.red); 


    } 
} 
} 

は、第二のクラスであるあなたは二回、両方ここにActionListenerを追加しました：ここ

ObjectChanger listener = new ObjectChanger(); 
selectOne.addActionListener (listener); 
selectTwo.addActionListener (listener); 
selectThree.addActionListener (listener); 

と：

selectOne.addActionListener(new ObjectChanger()); 
selectTwo.addActionListener(new ObjectChanger()); 
selectThree.addActionListener(new ObjectChanger()); 

セカンドますcurrentShapeの値を使用してJPanelsの形状を変更しようとしましたが、switchステートメントはインクリメントしたいだけなので賢明でした。変更シェイプメソッドを呼び出さなかったので、実際には何もしませんでした。 ImagePanelクラスにincrementCurrentメソッドを追加しました。

public void incrementCurrent(){ 
    currentShape++; 
    if(currentShape>3) 
     currentShape=0; 
    changeShape(currentShape); 
} 

これで値が変更され、形状が再描画されるようになりました。
