你从控制台输入字符串，跟你程序里面写死的字符串比较是有差异的。原因是从控制台通过IO流来读取的字符串里面包含了其他附加信息（如，你按的回车键...），程序里面写死的字符串则只包含里那几个字而已。你可以直接把程序里的B换成"苦心人天不负",就OK了。

HBuilder是DCloud（数字天堂）推出的一款支持HTML5的Web开发IDE。HBuilder的编写用到了Java、C、Web和Ruby。HBuilder本身主体是由Java编写，它基于Eclipse，所以顺其自然地兼容了Eclipse的插件。快，是HBuilder的最大优势，通过完整的语法提示和代码输入法、代码块等，大幅提升HTML、js、css的开发效率。

你只需要将数组内容换成你自己写的内容就行
什么意思？就网页上面有一个文本框，让学生写诗歌（文字），然后系统进行验证对不对是吗？
