これは私の最初の質問です
私はJavaでパズルゲームを作成します:
public class ImageJoorichin extends JApplet implements KeyListener {
Image myImage,alaki;
boolean preViewImage = true; // Control First PreView before Shuffle
int n, // bord higth & wight
blankX, // Blank X Coordinates
blankY; // Blank Y Coordinates
int[][] board;
public void init() {
myImage = getImage( getCodeBase(), "Screen Shot 1391-12-22 at 12.54.54 PM.png" );
String temp = JOptionPane.showInputDialog(rootPane, "Enter Size of Board", "Board Size", 2);
n = Integer.parseInt( temp );
board = new int[ n ][ n ];
temp = JOptionPane.showInputDialog(rootPane, "1-Easy\n2-Normal\n3-Hard", "Level Defficulty", 2);
int alaki = Integer.parseInt( temp ),
numberOfShuffle = 0;
switch( alaki ) {
case 1:
numberOfShuffle = n * n;
break;
case 2:
numberOfShuffle = n * n * n;
break;
case 3:
numberOfShuffle = n * n * n * n;
break;
}
repaint();
set();
setSize( 400, 400 );
shuffle( numberOfShuffle );
setFocusable(true);
requestFocus();
this.addKeyListener(this);
}
public void start() {
//repaint();
}
// For New Set & Orginaze Table
public void set() {
blankX = blankY = n - 1;
for( int i = 0; i < board.length; i++ ) {

シャッフルする前に画像のプレビューを表示しようとしています。
しかし、私はできません！でやろうとしましたが、表示されませんgraphic.drawImage()...しかし、コードを置き換えると機能するため、コードは機能してgraphic.drawLine()います
