用JAVA编写一个简单的生日提醒器，源代码该怎么写啊？
获取系统时间java猜生日源代码：
import java.util.*;
import java.text.*;
public class TestDate {
public static void main(String[] args) {
Calendar ca = Calendar.getInstance();
int year = ca.get(Calendar.YEAR);//获取年份
int month=ca.get(Calendar.MONTH);//获取月份
int day=ca.get(Calendar.DATE);//获取日
int minute=ca.get(Calendar.MINUTE);//分
int hour=ca.get(Calendar.HOUR);//小时
int second=ca.get(Calendar.SECOND);//秒
int WeekOfYear = ca.get(Calendar.DAY_OF_WEEK);
}
用系统时间跟生日比较就行java猜生日源代码了
java 这个是输入生日然后算出 从生日到现在 活了多少天 求代码
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Scanner;
/*
* 控制台输入生日,计算到今天为止进过java猜生日源代码了多少天
* 输入生日java猜生日源代码的格式:yyyy-MM-dd
*/
public class WorkDemo {
public static void main(String[] args) throws ParseException {
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
Scanner sc = new Scanner(System.in);
System.out.print("请输入java猜生日源代码你java猜生日源代码的生日, 输入格式为:yyyy-MM-dd");
String birthday = sc.nextLine();
Date birDate = sdf.parse(birthday);
Date now = new Date();
long time = now .getTime() - birDate.getTime();
long day = time/1000/60/60/24;
System.out.println("到今天经历了:"+day+"天");
}
}
用Java的Date类输入一个人的生日并输出，求代码。
//生日字符串和整型
String birthDateString = "1999-09-09";
int year = 1999;
int month = 9;
int day = 9;
//将字符串转换为Date
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
//dateFormat = DateFormat.getInstance();
Date birthDate = dateFormat.parse(birthDateString);
System.out.println(birthDate);
//构建Datejava猜生日源代码，已不推荐使用。年份从1900年开始java猜生日源代码，月份从0开始
birthDate = new Date(year - 1900, month - 1, day);
System.out.println(birthDate);
//Calendar类，月份从0开始
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.YEAR, year);
calendar.set(Calendar.MONTH, month- 1);
calendar.set(Calendar.DAY_OF_MONTH, day);
calendar.set(Calendar.HOUR_OF_DAY, 0); //设置时分秒
calendar.set(Calendar.MINUTE, 0);//设置时分秒
calendar.set(Calendar.SECOND, 0);//设置时分秒
calendar.set(Calendar.MILLISECOND, 0);//毫秒。。。
System.out.println(calendar.getTime());
代码简单java作业求救，生日“悖论
import java.util.Collections;
import java.util.HashSet;
import java.util.Random;
import java.util.Set;
public class BirthdayTester {
public int[] createBirthdays(int n) {
return new int[n];
}
public Integer[] fillBirthdays(int[] birthday) {
final Integer[] array = new Integer[birthday.length];
final Random random = new Random();
for (int i = 0; i birthday.length; i++) {
final int count = 1 + random.nextInt(365);
array[i] = count;
}
return array;
}
public boolean isExists(Integer[] birthday) {
final SetInteger mySet = new HashSetInteger();
Collections.addAll(mySet, birthday);
return mySet.size() != birthday.length;
}
public static void main(String... args) {
final BirthdayTester tester = new BirthdayTester();
for (int j = 5; j = 100; j = j + 5) {
for (int i = 1; i = 10; i++) {
final StringBuilder builder = new StringBuilder();
builder.append("The birthday experiment worked "
+ i + "/10 times for " + j + " people ");
if (tester.isExists(
tester.fillBirthdays(tester.createBirthdays(j)))){
builder.append(" - found");
} else {
builder.append(" - not found");
}
System.out.println(builder.toString());
}
System.out.println();
}
}
}
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) {
e.printStackTrace();
}
}
//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(){
return cld.get(6);
}
//获取该日是星期几
public String getDate(){
int date = cld.get(7);
return getWeekday(date);
}
//判断解析一周7天的值
public String getWeekday(int dayofweek){
switch(dayofweek){
case 1: return "星期日";
case 2: return "星期一";
case 3: return "星期二";
case 4: return "星期三";
case 5: return "星期四";
case 6: return "星期五";
case 7: return "星期六";
default:return "error";
}
}
public static void main(String[] args) {
GetBirth gb = new GetBirth();
gb.setDate(gb.year, gb.month, gb.day);
System.out.println(gb.getDay());
System.out.println(gb.getDate());
}
}
