身份证信息中间变星

定义一个工具类把下面代码放进去等到需要获取的时候调用就可以

public class StringXing {

public static String xingName(String name) {
String result = "";
result = name.substring(0, 1);
for (int i = 0; i < name.length(); i++) {
result += "*";
}
return result;
}
public static String xingID(String id) {
String result = "";
if(id.length() > 4)
{
result = id.substring(0, 4);
result += "****";
result += id.substring(id.length() - 4, id.length());
}
return result;
}
public static void main(String[] args) {
String s = StringXing.xingID("11010319840114183X");
System.out.println(s);
}

}

调用方法如下

idCode = StringXing.xingID(idCode);
