Question

我有一个java项目的迷你项目，我有一些挫折。

我想将按键的值传递给我的主类，以便调用一些方法，这些方法会在矩阵内上下左右移动某个值，然后根据值绘制GUI在那个矩阵里面。

这是我的类，它返回我在GUI中按下的键的键代码。

import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import javax.swing.JFrame;

public class Keys extends JFrame  implements KeyListener{
public static int keyVALUE;//I want to use this value inside another class
  public Keys()
   {
      addKeyListener( this ); 
   }

    public void keyReleased(KeyEvent e) {
    displayInfo(e);
   }

@Override
public void keyPressed(KeyEvent arg0) {
    // TODO Auto-generated method stub

}

@Override
public void keyTyped(KeyEvent arg0) {
    // TODO Auto-generated method stub
}

 private  int displayInfo(KeyEvent e){


        int id = e.getID();
        if (id == KeyEvent.KEY_TYPED) {
            char c = e.getKeyChar();
        } else {
             keyVALUE = e.getKeyCode();

            System.out.print(keyVALUE);

}
           return keyVALUE;}
}

我创建并想要修改矩阵的主要类是这个。

 import javax.swing.JFrame;
 import javax.swing.JOptionPane;




 public class Matrix extends Keys {
public static int[][] Matrix = new int[9][9];


public void moveUp(){

}

public void moveDown(){

}
public void moveLeft(){

}
public void moveRight(){

}

public static void main(String[] args) 
{      
             //since there is no GUI, here is a frame that picks up the key releases

             Keys keyPressed = new Keys();
         keyPressed.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
         keyPressed.setSize( 800, 600 ); // set frame size
         keyPressed.setVisible( true); // display frame 


         //set "car "2" and blocks "1" and paint GUI based on this
    for (int i = 0; i <9; i++) {
        for (int j = 0; j < 9; j++) {
            Matrix[i][j] = 0ș
            Matrix[4][4]=2;//start position

            System.out.print(Matrix[i][j] + " ");
            }
            System.out.println();
            }

        for(;;){
        try {
            Thread.sleep(500);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        System.out.println();

        for (int i = 0; i <9; i++) {
            for (int j = 0; j < 9; j++) {

        if(Matrix[i][j]==2 && Matrix[i-1][j]==0){

        Matrix[i-1][j]=2;
        Matrix[i][j]=0;
        Matrix[i][j]=Matrix[i-1][j];
        Matrix[i-1][j]=2;
        Matrix[i][j]=0;

        }}}


        for (int i = 0; i <9; i++) {
        for (int j = 0; j < 9; j++) {

        System.out.print(Matrix[i][j] + " ");
        }
        System.out.println();
        }

        if(Matrix[0][4]==2){JOptionPane.showMessageDialog(null,"You               WON!","Winner",JOptionPane.INFORMATION_MESSAGE);break;}
        if(Matrix[0][8]==2){break;}
        }
        }
 }

知道我怎么能这样做吗？有没有类似我的程序的例子？

感谢您的帮助和指导！
