拿去玩 JAVA新建文件命名为 Tetris 以前写的 懒得布置界面

dowhile 循环是 while 循环的变种。
该循环程序在初次运行时会首先执行一遍其中的代码，然后当指定的条件为 true 时，它会继续这个循环。
所以可以这么说，dowhile 循环至少执行一遍其中的代码，即使条件为 false，因为其中的代码执行后才会进行条件验证。

现在来分析：
(1)：先执行到最后一个e 的时候：
do{
result=patt1.exec("The best things in life are free");
document.write(result);
}
这时页面上的result就是eeeeee

(2)：下来继续验证执行
result的值e799bee5baa6e79fa5e98193e78988e69d83361为eeeeee，
while判断result不为空，又继续执行
do{
result=patt1.exec("The best things in life are free");
document.write(result);
}
这时指针已经到了末尾，返回的就是null。

所以document.write(result)就打印了null。
加起来就是eeeeeenull。

这个问题所在就是，你要理解了do while的运行原理。
它是先执行代码，再去验证。
遇到问题不解的时候，可以跟着程序一步一步的去查看，为什么会出现null ，是从哪里出来的，搞清楚了它的“错误”步骤，结合掌握的do while 就会想通了。

希望可以帮到你，^_~
没必要。有些知识时间久了自然就会了。可以试着写点其它的小东西。

1、互联网上有现成的例子，是用excel的二次开发语言VBA写的。
2、代码很多不copy能都贴上来。需要的话可以给你发邮件。
3、具体方法就是先做好用户窗体
4、做好方块的模型zd
5、方向键控制方块的移动
6、方块的生成是随机的
