18为身份证号码的第17位数字表示性别:奇数表示男性,偶数表示女性
所有代码中,只要截取出第17位的数字出来就可以判断性别,如:
String sex;
// 判断性别
if (Integer.parseInt(CardCode.substring(16).substring(0, 1)) % 2 == 0) {
sex = "女";
} else {
sex = "男";
}

如果只要判断有非法的字符(除0-9和Xx外)可用正则表达式publicstaticvoidmain(String[]args){//TODOcodeapplicationlogichereStrings="2142213weqrwe32";StringregEx="[^0-9Xx]";Patternpat=Pattern.compile(regEx);Matchermat=pat.matcher(s);booleanrs=mat.find();if(rs){System.out.print("有非法字符");}另外,校验身份证号码有专门程序的,可直接校验身份证号是否正确,在自己在网上找下
