求解用java語言 編寫一個身份證的類，可以用來驗證身份證的長度，并可以顯示地址碼，生日，性別。

public static void main(String[] args){

Scanner input = new Scanner(System.in);

System.out.println("請輸入十八位身份證號碼！");

String id=input.next();

if(id.length()!=18){

System.out.println("身份證號碼長度不對！");

}

String top=id.substring(0, 17);

String sishu="7,9,10,5,8,4,2,1,6,3,7,9,10,5,8,4,2";

String[] xishu=sishu.split(",");

int sum=0;

for (int i = 0; i top.length(); i++) {

int a=Integer.parseInt(top.charAt(i)+"");

int b=Integer.parseInt(xishu[i]);

sum+=a*b;

}

int xiaoyanjisuan=sum%11;

int xiaoyan=Integer.parseInt(id.substring(17, 18));

if(xiaoyanjisuan==xiaoyan){

System.out.println("身份證號碼檢測正確！");

}else{

System.out.println("身份證號碼檢測錯誤！");

return;

}

String dizhi=id.substring(0,6);

String nian=id.substring(6,10);

String yue=id.substring(10, 12);

String ri=id.substring(12,14);

int sex=Integer.parseInt(id.substring(16,17));

System.out.println("地址碼為："+dizhi);

System.out.println("生日為："+nian+"年"+yue+"月"+ri+"日");

if(sex%2==0){

System.out.println("性別為：女");

}else{

System.out.println("性別為：男");

}

}

用java編寫驗證身份證是否正確的程序代碼~

System.out.println("請輸入你的身份證號碼");

String ID=input.next();

if(ID.lenth()==18)｛

System.out.println("輸入正確")；

｝else{

System.out.println("輸入錯誤");

}

java編程輸入18位身份證號辦別女性男女 代碼？

18為身份證號碼的第17位數(shù)字表示性別：奇數(shù)表示男性，偶數(shù)表示女性

所有代碼中，只要截取出第17位的數(shù)字出來就可以判斷性別，如：

String sex;

// 判斷性別

if (Integer.parseInt(CardCode.substring(16).substring(0, 1)) % 2 == 0) {

sex = "女";

} else {

sex = "男";

}

java源代碼是給你一個身份證號，通過面板身份證號的輸入，顯示出該身份證主人的出生年月，省份，性別等資料

我當初用struts1和hibernate做了個簡單的！主要的邏輯代碼在下面！數(shù)據(jù)庫里號碼對應的城市在網(wǎng)上可以查的到

package dao;

import java.text.ParseException;

import java.text.SimpleDateFormat;

import java.util.Calendar;

import java.util.Date;

public class IdDao {

private static Configuration configuration = new Configuration().configure() ;

private static SessionFactory sessionFactory =configuration.buildSessionFactory();

private static Session session = null;

public Info query(String s){

Info info = null;

StringBuffer stringBuffer = new StringBuffer(s);

if(s.length()==18){

String end = stringBuffer.substring(17);

//System.out.println(end);

if(!end.matches("\\d||x")){

return null;

}

}

else if(s.length()==15){

stringBuffer.insert(6, "19");

stringBuffer.append("3");

}

int i = Integer.parseInt(stringBuffer.substring(0, 6));

//System.out.println(i);

session = sessionFactory.openSession();

Criteria criteria = session.createCriteria(Shenfenzhen.class);

criteria.add(Expression.eq("num", i));

ListShenfenzhen list = criteria.list();

String address = null;

try {

address = list.get(0).getAddress();

}catch (Exception e) {

return null;

}

i = Integer.parseInt(stringBuffer.substring(16,17));

String sex = null;

if(i%2==0){

sex = "女";

}else{

}

//System.out.println(i);

stringBuffer = new StringBuffer(stringBuffer.substring(6, 14));

// stringBuffer.insert(4, "-");

// stringBuffer.insert(7, "-");

//System.out.println(stringBuffer);

String ss = stringBuffer.toString();

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMdd");

String brithday="";

int year=0;

int month =0;

int day =0;

try {

Date date = dateFormat.parse(ss);

//System.out.println(date);

Calendar calendar = Calendar.getInstance();

calendar.setTime(date);

year = calendar.get(Calendar.YEAR);

month = calendar.get(Calendar.MONTH)+1;

brithday = (String)(year + "年" + month + "月" + day + "日");

if(nowYearyear){

}

closeSession(session);

return info;

}

// public static void main(String[] args){

// System.out.println("x".matches("\\d||x"));

// }

private void closeSession(Session session){

if(session !=null){

session.close();

}

}

用java編個驗證身份證的小系統(tǒng)

public class admin {

static boolean ID_number(String ID_number)

{

if(ID_number.length()==15)

{

for(int i=0;iID_number.length();i++)

{

if(Character.isDigit(ID_number.charAt(i)))

{

}

else

{

return false;

}

}

}else if(ID_number.length()==17)

{

for(int i=0;iID_number.length();i++)

{

if(Character.isDigit(ID_number.charAt(i)))

{

}

else

{

if(i==16ID_number.charAt(i)=='X')

{

}

else

{

return false;

}

}

}

}

else

{

System.out.println("輸入的身份證號碼有誤");

return false;

}

return true;

}

public static void main(String[] args) {

System.out.println(ID_number("1111111111111111X"));

}}

java代碼怎么校驗身份證號碼含有非法字符

如果只要判斷有非法的字符(除0-9和Xx外)可用正則表達式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,校驗身份證號碼有專門程序的,可直接校驗身份證號是否正確,在自己在網(wǎng)上找下
