私は正方形を作成し、私のメイン関数で呼び出すことができるクラスを作成しようとしています

Question

私の意図は、正方形を作成して私のメインクラス（2スレッドCanvasとJFrameのクラス）が動作しないように見えます（何もしません）...実装するには実行可能な方法ですか、それとも表示されるクラスと同じクラスに四角形を作成する必要がありますか？

PD：私の下手な英語

import java.awt.Canvas; 
import java.awt.Color; 
import java.awt.Graphics; 

public class Quadrat extends Canvas{ 

    public static int x; 
    public static int y; 
    public static int status; 

    private static int totalX; 
    private static int totalY; 

    public static boolean isRed; 
    public static boolean isBlue; 

    public Quadrat(int x, int y, int ampleTotal, int totalX, boolean isRed, boolean isBlue, int status) { 
     this.x = x; 
     this.y = y; 
     this.totalX = totalX; 
     this.totalY = totalY; 
     this.isRed = isRed; 
     this.isBlue = isBlue; 
     this.status = status; 
    } 

    public void paint(Graphics g) { 
     if (isRed) { 
      g.setColor(Color.RED); 
     } 
     else { 
      g.setColor(Color.BLUE); 
     } 

     g.fillRect(x, y, totalX/3 , totalY/3); 
    } 
    public static void main() { 
     System.out.println("Is working"); 
    } 
} 

のため申し訳ありませんがここで私はメインクラスでそれを初期化する場所です：

public void paint(Graphics g) { 
    /* 
    * Border 
    */ 
    g.setColor(Color.BLACK); 
    g.fillRect(AMPLE/3, 0, GRUIX, ALTURA); 
    g.fillRect((AMPLE/3) * 2, 0, GRUIX, ALTURA); 
    g.fillRect(0, ALTURA/3, AMPLE, GRUIX); 
    g.fillRect(0, (ALTURA/3) * 2, AMPLE, GRUIX); 

    /* 
    * Square 
    */ 

    Quadrat quadrat = new Quadrat(0, 0, AMPLE, ALTURA, true, false, 0); 

}

     this.x = x; 
     this.y = y; 
     this.totalX = totalX; 
     this.totalY = totalY; 
     this.isRed = isRed; 
     this.isBlue = isBlue; 
     this.status = status; 
    } 

    public void paint(Graphics g) { 
     if (isRed) { 
      g.setColor(Color.RED);

MainCanvas.java

import java.awt.Canvas;

import java.awt.Graphics; 

public class MainCanvas extends Canvas { 

    private Quadrat quadrat; 

    private int AMPLE = 10; 
    private int GRUIX = 300; 
    private int ALTURA = 300; 

    public MainCanvas() { 
     quadrat = new Quadrat(0, 0, 100, 100, true, false, 0); 
    } 

    public void paint(Graphics g) { 
     g.setColor(Color.BLACK); 
     g.fillRect(AMPLE/3, 0, GRUIX, ALTURA); 
     g.fillRect((AMPLE/3) * 2, 0, GRUIX, ALTURA); 
     g.fillRect(0, ALTURA/3, AMPLE, GRUIX); 
     g.fillRect(0, (ALTURA/3) * 2, AMPLE, GRUIX); 

     quadrat.paint(g); 
    } 

} 

MyPanel.java

public MyPanel() { 
    mainCanvas = new MainCanvas();

@Override

Main.java

public class Main extends JPanel { 

    private int AMPLE = 300;

    private Quadrat quadrat = new Quadrat(0, 0, AMPLE, ALTURA, true, false, 0); 

    public static void main(String[] args) { 
     Main main = new Main(); 

     JFrame frame = new JFrame("Main"); 
     frame.setExtendedState(frame.getExtendedState() | JFrame.MAXIMIZED_BOTH); // maximize window 
     frame.setLayout(new BorderLayout());

クワタ。 java

import java.awt.Canvas; 
import java.awt.Color; 
import java.awt.Graphics; 

public class Quadrat extends Canvas { 

    public int x; 
    public int y; 
    public int status; 

    private int totalX; 
    private int totalY; 

    public boolean isRed; 
    public boolean isBlue; 

    public Quadrat(int x, int y, int totalX, int totalY, boolean isRed, boolean isBlue, int status) { 
     this.x = x; 
     this.y = y; 
     this.totalX = totalX; 
     this.totalY = totalY; 
     this.isRed = isRed; 
     this.isBlue = isBlue; 
     this.status = status; 
    } 

    public void paint(Graphics g) { 
     if (isRed) { 
      g.setColor(Color.RED); 
     } else { 
      g.setColor(Color.BLUE); 
     } 

     g.fillRect(x, y, totalX, totalY);
