用Java做 在輸入文本框里輸入出生年月，然后輸出年齡，怎么做啊～！

用JLabel 或Label

我給你寫了個開頭

public class mainFrame extends JFrame{

JLabel jl = new JLabel("用戶名稱:");

JTextField jtf = new JTextField();

JPanel jp_group = new JPanel();

public loginFrame() {

try {

jbInit();common.mysession.dataTrf.getValue("main");

} catch (Exception exception) {

exception.printStackTrace();

}

}

幫忙寫下代碼java swing,個人信息實例

本人急忙做的:有什么不合要求的請再告訴我：

package?show;

import?javax.swing.*;

import?java.awt.*;

import?java.awt.event.ActionEvent;

import?java.awt.event.ActionListener;

public?class?Test?extends?JFrame?implements?ActionListener

{

GridBagLayout?g=new?GridBagLayout();

GridBagConstraints?c=new?GridBagConstraints();

Test(String?str)

{

super(str);

setSize(300,500);

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

setLayout(g);

//調用方法

addComponent();

submit.addActionListener(this);

setVisible(true);

setLocationRelativeTo(null);//設居中顯示;

}

//在這個方法中將會添加所有的組件;

//使用的網格包布局;希望樓主能看懂;

public?void?addComponent()

{

//個人信息登記

noteInformation=new?JLabel("個人信息登記：");

add(g,c,noteInformation,0,0,1,1);

//用戶名

userName=new?JLabel("用戶名：");

add(g,c,userName,0,1,1,1);

//用戶名輸入框

textUserName=new?JTextField(10);

add(g,c,textUserName,1,1,2,1);

//密碼：

password=new?JLabel("密碼：");

add(g,c,password,0,2,1,1);

//密碼輸入框

textUserPassword=new?JTextField(10);

add(g,c,textUserPassword,1,2,2,1);

//性別

sex=new?JLabel("性別:");

add(g,c,sex,0,3,1,1);

//男?女單選框

sexMan=new?JRadioButton("男");

add(g,c,sexMan,1,3,1,1);

sexGirl=new?JRadioButton("女");

add(g,c,sexGirl,2,3,1,1);

ButtonGroup?group=new?ButtonGroup();

group.add(sexMan);

group.add(sexGirl);

//出生日期

birthday=new?JLabel("出生日期:");

add(g,c,birthday,0,4,1,1);

//復選框及其內容

String[]?YEARS=new?String[65];

for(int?i=1950,k=0;i=2014;i++,k++)

{

YEARS[k]=i+"年";

}

year=new?JComboBox(YEARS);

add(g,c,year,1,4,1,1);

//復選框及內容

month=new?JComboBox(MONTH);

add(g,c,month,2,4,1,1);

//submit按鈕

submit=new?JButton("submit");

c.insets=new?Insets(7,0,4,0);

add(g,c,submit,1,5,1,1);

result=new?JTextArea(15,20);

add(g,c,result,0,6,3,4);

}

/* public?void?ActionPerformed(ActionEvent?e)

{

String?s=textUserName.getText();

String?k=sexMan.getText();

String?v=sexGirl.getText();

String?a=(String)?year.getSelectedItem();

String?b=(String)month.getSelectedItem();

String?num="用戶名："+s+"\n"+"密碼:?"+t+"性別:?"+(k==null?v:k)+"\n"+"出生日期:"+a+"?"+b;

result.append(num);

}*/

public?void?add(GridBagLayout?g,GridBagConstraints?c,JComponent?jc,int?x?,int?y,int?gw,int?gh)

{

c.gridx=x;

c.gridy=y;

c.anchor=GridBagConstraints.WEST;

c.gridwidth=gw;

c.gridheight=gh;

g.setConstraints(jc,c);

add(jc);

}

public?static?void?main(String?args[])

{

new?Test("個人信息登記表");

}

JLabel?noteInformation,userName,password;

JLabel?sex,birthday;

JTextField?textUserName,textUserPassword;

JRadioButton?sexMan,sexGirl;

JComboBox?year,month;

JButton?submit;

JTextArea?result;

final?String[]?MONTH={"1月","2月","3月","4月","5月","6月","7月","8月","9月","10月","11月","12月"};

@Override

public?void?actionPerformed(ActionEvent?arg0)

{

String?s=textUserName.getText();

String?t=textUserPassword.getText();

String?k=sexMan.getText();

String?v=sexGirl.getText();

String?a=(String)?year.getSelectedItem();

String?b=(String)month.getSelectedItem();

String?num="用戶名："+s+"\n"+"密碼:?"+t+"\n?性別:?"+(k==null?v:k)+"\n"+"出生日期:"+a+"?"+b;

result.setText(num);

}

}

java中的年月日簡單編程

將這段代碼拷貝到UseBirthday類中和你的比較一下看看

public class UseBirthday {

public static void main(String[] args) {

Birthday a=new Birthday(2000,1,1);

a.GetBirthday();

a.Birthday(2008,5,12);

a.GetBirthday();

}

}

class Birthday {

private int Year, Month, Day;

Birthday(){

Year=2000;

Month=1;

Day=1;

}

Birthday(int y,int m,int d) {

Year = y;

Month = m;

Day = d;

}

public void Birthday(int y,int m,int d){

Year = y;

Month = m;

Day = d;

}

int Gety() {

return Year;

}

int Getm() {

return Month;

}

int Getd() {

return Day;

}

void GetBirthday() {

System.out.println(Gety() + "年" + Getm() + "月" + Getd() + "日");

}

}

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！數據庫里號碼對應的城市在網上可以查的到

package dao;

import java.text.ParseException;

import java.text.SimpleDateFormat;

import java.util.Calendar;

import java.util.Date;

import java.util.List;

import org.hibernate.Criteria;

import org.hibernate.Session;

import org.hibernate.SessionFactory;

import org.hibernate.cfg.Configuration;

import org.hibernate.criterion.Expression;

import entity.Shenfenzhen;

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{

sex = "男";

}

//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;

day = calendar.get(Calendar.DAY_OF_MONTH);

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

} catch (ParseException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

info = new Info(address, brithday, sex);

Calendar c = Calendar.getInstance();

int nowYear = c.get(Calendar.YEAR);

int nowMonth = c.get(Calendar.MONTH);

int nowDay = c.get(Calendar.DAY_OF_MONTH);

if(nowYearyear){

info = null;

}else if(nowYear ==year nowMonthmonth ){

info = null;

}else if(nowYear == year nowMonth==month nowDayday){

info = null;

}

closeSession(session);

return info;

}

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

// IdDao dao = new IdDao();

// dao.query("342522998711224513");

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

// }

private void closeSession(Session session){

if(session !=null){

session.close();

}

}

}

JAVA寫一個程序，要求輸入身份證號獲取所在地區代碼也就是前六位，和出生年月。

import?java.util.*;

public?class?Yugi{

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

Scanner?scan?=?new?Scanner(System.in);

System.out.println("輸入身份證號碼:?");

String?code?=?scan.nextLine().trim();

scan.close();

String?reg?=?"^(.{6})(.{4})(.{2}).*$";

String?a?=?code.replaceAll(reg,?"$1");

String?y?=?code.replaceAll(reg,?"$2");

String?m?=?code.replaceAll(reg,?"$3");

System.out.println("所在地區代碼："?+?a);

System.out.println("出生年月:?"?+?y?+?",?"?+?m);

}

}
