Java 中文姓名随机生成

项目要求产生一些模拟的中文姓名，我的想法是先产生姓氏，再随机产生名字，可以是两个字的也可以是三个字的。使用的是

GB2312实现的中文字，可自行百度“信息交换用汉字编码字符集”了解一下这种编码对汉字的安排。我这里简单写一下我的理解。

汉字以两个字节存储，称为“区位码”，高位叫区码，低位叫位码，有这俩字节组成汉字。假设有一张汉字表，横竖都是 94列，那么区码就相当于行，位码就相当于列，根据行列就可以确定一个汉字了，这有点像二位数组＝＝，GB2312大致就是按照这种方式实现的，区码１～９即前９行放的是特殊字符，１６～５５区放的是一级汉字，５６～８７区放的是二级汉字，其余的暂时空余。为了区别中文与西文字母，在中文字符首位以１开头区分以０开头的ASCII码，GB2312给每个中文字符加上0xA0，因此，区码从0xB0-0xF7 都是汉字，位码范围0xA0-0xFE 。

上面产生的还是比较随机的姓名，需要筛选一下才能使用==，为了提高可靠性，可以从三个方向下手一是提高普遍姓氏如张王李赵的频率，二是只使用一级汉字，因为这些字比较常见，三是可以加入一些常见的名字如伟，明，静，月，斌，磊作为一个名字数组的候选方案，这样可以更加真实一些，有兴趣的朋友可以尝试一下。

分享促进社会进步~~
