我做了一个图片拼图游戏。实际上我使用Netbeans 8.2 GUI Builder来创建游戏，我做了Timer并移动。
但我很困惑如何改变图像。我在各个网站上搜索过但没有帮助。
这是我的代码：
package projetu;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.ImageIcon;
import javax.swing.Timer;
import static projetu.fasil.cont;
public class t02 extends javax.swing.JFrame {
static int cont = 0;
int i = 0;
private Timer timer;
private int currentSegundo = 0;
private int currentMinuto = 0;
private int currentHora = 0;
private int velocidade = 1000;
public t02() {
initComponents();
b9.setVisible(false);
}
public void contamuda() {
txtconta.setText(String.valueOf(cont++));
}
private void iniciarContagem() {
ActionListener action;
action = new ActionListener() {
public void actionPerformed(ActionEvent e) {
currentSegundo++;
if (currentSegundo == 60) {
currentMinuto++;
currentSegundo = 0;
}
if (currentMinuto == 60) {
currentHora++;
currentMinuto = 0;
}
String hr = currentHora <= 9 ? "0" + currentHora : currentHora + "";
String min = currentMinuto <= 9 ? "0" + currentMinuto : currentMinuto + "";
String seg = currentSegundo <= 9 ? "0" + currentSegundo : currentSegundo + "";
tempu.setText(hr + ":" + min + ":" + seg);
}
};
this.timer = new Timer(velocidade, action);
this.timer.start();
}
