java猜生日代码
java编写一个简单的输入生日计算下一个生日时间的代码?
import java.util.Calendar;
import java.util.Scanner;
import java.util.concurrent.TimeUnit;
/**

*/
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("请输入你的姓名：");
String name = sc.nextLine();
String line = sc.nextLine();
String[] strs = line.split("/");
if (days == 0) {
System.out.println(String.format("%s 同学,今天是你的生日,祝你生日快乐(#^.^#)", name, days));
} else {
System.out.println(String.format("%s 同学离自己最近下一次生日%d天.", name, days));
}
System.out.println("生日输入不正确！请按格式输入.");
sc.close();
* 获取最近一次生日天数
* @param year
* @param month
* @param day
* @return
public static int getDays(String year, String month, String day) {
Calendar now = Calendar.getInstance();
now.set(Calendar.HOUR_OF_DAY, 0);
now.set(Calendar.MINUTE, 0);
now.set(Calendar.SECOND, 0);
now.set(Calendar.MILLISECOND, 0);
int now_year = now.get(Calendar.YEAR);
Calendar birthday = Calendar.getInstance();
birthday.set(Calendar.YEAR, now_year);
birthday.set(Calendar.MONTH, Integer.parseInt(month) - 1);
birthday.set(Calendar.DAY_OF_MONTH, Integer.parseInt(day));
birthday.set(Calendar.HOUR_OF_DAY, 0);
birthday.set(Calendar.MINUTE, 0);
birthday.set(Calendar.SECOND, 0);
birthday.set(Calendar.MILLISECOND, 0);
long diff = now.getTimeInMillis() - birthday.getTimeInMillis();
if (diff == 0) {
return 0;
} else if (diff 0) {
long diffDays = TimeUnit.DAYS.convert(diff, TimeUnit.MILLISECONDS);
return Math.abs((int) diffDays);
birthday.add(Calendar.YEAR, 1);
long diffMi = birthday.getTimeInMillis() - now.getTimeInMillis();
long diffDays = TimeUnit.DAYS.convert(diffMi, TimeUnit.MILLISECONDS);
return (int) diffDays;
用JAVA编程,输入自己的生日,判断自己生日是当年中的第几天和星期几.
import java.io.*;
import java.util.*;
public class GetBirth {
int year = 0;
int month = 0;
int day = 0;
Calendar cld = Calendar.getInstance();//创建一个日历
public GetBirth(){
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
System.out.println("请输入年、月、日：");
try {
year = Integer.parseInt(in.readLine());
month = Integer.parseInt(in.readLine());
day = Integer.parseInt(in.readLine());
} catch (NumberFormatException e) {
e.printStackTrace();
} catch (IOException e) {
//将日历时间设置成生日那天
public void setDate(int year,int month,int day){
cld.set(year,month-1,day);
//获取该日是一年当中的第几天
public int getDay(){
//获取该日是星期几
public String getDate(){
return getWeekday(date);
public String getWeekday(int dayofweek){
switch(dayofweek){
case 1: return "星期日";
default:return "error";
GetBirth gb = new GetBirth();
gb.setDate(gb.year, gb.month, gb.day);
System.out.println(gb.getDay());
System.out.println(gb.getDate());
希望对楼主有所帮助,谢谢.
JAVA猜生日的程序
不知道这个猜生日的程序具体难度如何,是否会使用很复杂的算法
在一般公司里面,一般不会用到复杂的算法的,需要的是对java基础的掌握情况和其他的框架的知识,所以你只需要掌握牢java基础就好了
