在练字打字的过程之中，一直很好奇，这个打字速度到底可以有多快，目前我的英文的打字水平，估计也就是240字母/分钟。写出来这个打字程序也用于消遣使用，实现了自动打字的基本框架了。
（图一：金山打字通英文打字速度的测试界面）
首先我们要思考一个问题，就是如何才能让程序自动打字？
在我们打字的过程之中，是敲击键盘实现打字的，那么就需要让程序自动的模拟按键，是实现打字的过程。还有一点要考虑的过程就是，如何让计算机知道自己应该模拟的是那些文章。遇到每一个字符是如何处理，遇到特殊的符号，怎么办还有大小写问题。
对于模拟按键问题，这一块在几个月我写过一篇关于模拟按键的问题，已经说的很详细了。

现在我将设计展示给大家：
实现代码如下：

观看打字效果：
编译运行之后直接将光标放置在打字的软件上输入框就可以了。
备注：
这个软件我已经放置了在了gittee上面/shixiongyan/KingsoftTypingTools
测试文件的内容是：
test.txt
He became interested in two theories that possibly explained how cholera killed people. The first suggested that cholera multiplied in the air. A cloud of dangerous gas floated around until it found its victims. The second suggested that people absorbed this disease into their bodies with their meals. From the stomach the disease quickly attacked the body and soon the affected person died. John Snow suspected that the second theory was correct but he needed evidence. So when another outbreak hit London in 1854, he was ready to begin his enquiry. As the disease spread quickly through poor neighbourhoods, he began to gather information. In two particular streets, the cholera outbreak was so severe that more than 500 people died in ten days. He was determined to find out why.
