Java 记忆测试（Memory Test）小游戏的实现及GUI设计

辛明影老师的Java选修课相关。

记忆测试小游戏内容及流程见这一篇博文：C语言 记忆测试（Memory Test）小游戏的实现

时间进度条的添加没有成功，因此先不添加进度条，详见Java jProgressBar进度条的玄学;

（1）数字串输出

调用java.util.Random包中的random.nextInt()方法，通过一个循环产生指定长度的数字串。

（2）数字串消失

新建一个线程，通过线程的sleep()方法使数字串停留一定的时间，之后对所在的JLable进行清空内容的处理使数字串消失。

（3）数字串输入

在数字串显示在屏幕上的时候，对进行输入的文本字段进行.setEditable(false)操作使其不能输入内容，玩家只能记忆；数字串消失后通过.setEditable(true)使文本字段恢复编辑。

（4）游戏的判定

输入结束按钮的响应的事件除了包括以上的部分内容，还包括：判断输入的数字串是否和给定的相同，分别弹出不同的对话框：如果相同，数字串加长时间加长，游戏继续；如果不同，游戏结束，给出分数（猜对的数字串）长度之和。

• JAVA中修改JOptionPane的字体样式(Font)，但是按钮的字体设置不成功。

• java中怎么实现让一串字出现停留一会又消失的、 java sleep延时效果出不来、java 等待一秒方法，注意必须新建一个线程，在线程中sleep；
