随机输入一个姓名，然后分别输出姓和名，怎么写代码?谢谢!

Posted 2023-05-09

请问这个代码怎么写，如题!比如说一个人叫张三 他输出结果就是: 姓氏:张 名字:三 谢谢了!

具体的写法如下：

do case

case len(alltrim(姓名))=4

?left(allltrim(姓名),2),right(alltrim(姓名),2)

case len(姓名)=6

?left(allltrim(姓名),2),right(alltrim(姓名),4)

case len(姓名)=8

?left(allltrim(姓名),4),right(alltrim(姓名),4)

endcase

源代码主要功用有如下2种作用：

生成目标代码，即计算机可以识别的代码。

对软件进行说明，即对软件的编写进行说明。为数不少的初学者，甚至少数有经验的程序员都忽视软件说明的编写，因为这部分虽然不会在生成的程序中直接显示，也不参与编译。

但是说明对软件的学习、分享、维护和软件复用都有巨大的好处。因此，书写软件说明在业界被认为是能创造优秀程序的良好习惯，一些公司也硬性规定必须书写。

需要指出的是，源代码的修改不能改变已经生成的目标代码。如果需要目标代码做出相应的修改，必须重新编译。

参考技术A 三个字
二个字
四个字
单姓
复姓
考虑周全的情况下
do
case
case
len(alltrim(姓名))=4
?left(allltrim(姓名),2),right(alltrim(姓名),2)
case
len(姓名)=6
?left(allltrim(姓名),2),right(alltrim(姓名),4)
case
len(姓名)=8
?left(allltrim(姓名),4),right(alltrim(姓名),4)
endcase

性能测试脚本中的参数化数据源经常需要准备成千上万甚至更多的数据，例如手机号姓名。

如果通过java代码生成手机号以及姓名的数据工厂呢？

首先实现随机生成中文名，中文名是由姓和名组成的。

分别通过getChineseFamilyName和getChineseGivenName方法随机生成中文的姓和名。

getChineseFamilyName方法具体实现如下

public static String getChineseFamilyName(){

String str = null;

Random random=new Random(System.currentTimeMillis());

/* 598 百家姓 */

String[] Surname= {"赵","钱","孙","李","周","吴","郑","王","冯","陈","褚","卫","蒋","沈","韩","杨","朱","秦","尤","许",

 "何","吕","施","张","孔","曹","严","华","金","魏","陶","姜","戚","谢","邹","喻","柏","水","窦","章","云","苏","潘","葛","奚","范","彭","郎",

int index=random.nextInt(Surname.length-1);

str = Surname[index]; //获得一个随机的姓氏

return str;

}

getChineseGivenName方法具体实现如下

public static String getChineseGivenName() {

String str = null;

int highPos, lowPos;

Random random = new Random();

highPos = (176 + Math.abs(random.nextInt(71)));//区码，0xA0打头，从第16区开始，即0xB0=11*16=176,16~55一级汉字，56~87二级汉字

random=new Random();

lowPos = 161 + Math.abs(random.nextInt(94));//位码，0xA0打头，范围第1~94列

byte[] bArr = new byte[2];

bArr[0] = (new Integer(highPos)).byteValue();

bArr[1] = (new Integer(lowPos)).byteValue();

try {

str = new String(bArr, "GB2312");//区位码组合成汉字

} catch (UnsupportedEncodingException e) {

e.printStackTrace();

}

return str;

}

接下来实现生成手机号。一般手机号都是以130、186等等号段开始的11位阿拉伯数字组成。因此可以定义长整型变量。

例如定义186号段的手机号。

long mobileL = 18600000000L;

如何生成大量不重复的姓名以及手机号呢？通过循环来实现。

接下来需要实现的是文件的写入操作。writeContent方法实现的将指定的字符串写入到指定路径的文件名中，是否追加式写入设置为true。

writeContent方法具体实现如下

public static boolean writeContent(String c, String path, boolean isAppend) {

//File f = new File(path);

try {

FileOutputStream fos = new FileOutputStream(path, isAppend);

OutputStreamWriter writer = new OutputStreamWriter(fos, "UTF-8");

writer.write(c);

writer.close();

fos.close();

} catch (IOException e) {

e.printStackTrace();

return false;

}

return true;

}

最后在入口函数main通过循环调用姓名方法以及手机号变量累加实现批量产生数据。

定义mobileL、name、familyNameStr、filepath4个变量分别存放手机号、姓名、中文姓、文件路径。通过循环1000次生成1000条手机号、姓名记录。

main方法具体实现如下

public static void main(String[] args) {

   long mobileL = 18600000000L;

   String name = "";

   String familyNameStr="";

   String filepath = "E:\data\NameMobile.txt";

   for(int j=1;j<1001;j++){

mobileL = mobileL + 1L;

Random random = new Random(System.currentTimeMillis());

Boolean flag = random.nextBoolean();//随机标识

familyNameStr = getChineseFamilyName();

name = familyNameStr;

if(flag){//true,则名2个汉字

name += getChineseGivenName()+getChineseGivenName();

}else {//false,则名1个汉字

name += getChineseGivenName();

}

        writeContent(name+","+mobileL+" ",filepath,true);

}

}

注意，文件路径一定要存在，否则会报类似如下错误：

java.io.FileNotFoundException: E:dataNameMobile.txt (系统找不到指定的路径。)

运行代码生成数据如下所示
