以下是修改后的代码，实现了简单、普通、困难三种不同难度的拿火柴游戏：

    		win = false; 
    		showResult(); 
      	} else { 
      		tfPcshow.setText("电脑正在思考，请稍等...");

					comNum=(int)(Math.random()*3)+1; 
					break; 

				case 2: // 普通难度，电脑根据当前火柴数量计算拿取数量
					comNum=(sumMatch-1)%4; 
					if(comNum == 0) { 
						comNum = (int)(Math.random()*3)+1; 
					} 
					break; 

				case 3: // 困难难度，电脑使用人工智能算法计算拿取数量
          comNum=AI.calculate(sumMatch);
          break;

				default:
					return;
			}

			sumMatch -= comNum;

			if(sumMatch <= 0) { 
				win = true;
				showResult();
      } else {
      	tfPcshow.setText("电脑拿了 " + comNum + " 根火柴，轮到你了！");
      }

			tfLastshow.setText("剩余火柴数：" + sumMatch); 
		}
	}).start(); 	
}

private void showResult() { // 显示游戏结果的方法
	if(win) {
		JOptionPane.showMessageDialog(this, "恭喜你赢了！", "TEST", JOptionPane.INFORMATION_MESSAGE);
	} else {
		JOptionPane.showMessageDialog(this, "你输了，再试一次吧", "TEST", JOptionPane.INFORMATION_MESSAGE);
	}

	btnStart.setEnabled(true); // 结束后启用开始游戏按钮
	rbEasy.setEnabled(true); rbNormal.setEnabled(true); rbHard.setEnabled(true); // 启用单选按钮组
}

public static void main(String[] args) {
    Test1 frame = new Test1();
    frame.setVisible(true);
}

}

在新的代码中，增加了一个单选按钮组用来选择难度，共有三个选项：简单、普通、困难。根据不同的难度，电脑会采取不同的策略来拿取火柴。
