猜数字游戏
要求：用图形用户界面实现。
功能：计算机产生随机数，猜中即胜，猜不中，提示是大了还是小了，继续猜，直至猜
到，给出所用时间和评语。



这个写出来为什么不是随机数啊。。。

            lbTip.setText("请猜一猜这个数是多少？");

按照楼主要求写了一个，可以参考下。

谢谢谢谢啦，怎么给你分啊

我想问下主函数那一块儿是什么意思，throws Exception，，，是啥啊.。。。还有啊，，为什么没有找到程序的名字，，，没名字怎么运行啊，，，，看到一定要跟我说说，，谢谢了，，，帮人帮到底啊

程序名倒是找到了。。。可是throws Exception还是不懂哎

throws Exception 是抛出的异常

程序的名字可买 自己改吧，这个都 不是很重要吧，我觉得。
