java判断星座代码

java基础题,关于输入月日来判断星座的,求教

import java.text.ParseException; import java.text.SimpleDateFormat; import java.util.Calendar; import java.util.Date; import java.util.Scanner; public class Test { public static void main(String[] args) throws ParseException { Scanner scanner = new Scanner(System.in); // 只输入月、日,此代码未校验月、日输入是否合理,比如2月30 System.out.print("请输入你的出生月份"); int month = scanner.nextInt(); System.out.print("请输入你的出生日期"); int day = scanner.nextInt(); System.out.print("你的星座是:"); // 通过输入完整日期的方式判断,可以自动处理不合理日期,比如2月30 // SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd"); // System.out.print("请输入你的出生日期(形如2018-02-03):"); // Date birthday = dateFormat.parse(scanner.nextLine()); // // Calendar calendar = Calendar.getInstance(); // calendar.setTime(birthday); // int month = calendar.get(Calendar.MONTH) + 1; // int day = calendar.get(Calendar.DAY_OF_MONTH); // System.out.print("你的生日是 :" + dateFormat.format(birthday) + "\r\n你的星座是:"); scanner.close(); switch (month) { case 1: if (day System.out.println("摩羯座"); else System.out.println("水瓶座"); break; case 2: if (day System.out.println("水瓶座"); else System.out.println("双鱼座"); break; case 3: if (day System.out.println("双鱼座"); else System.out.println("白羊座"); break; case 4: if (day System.out.println("白羊座"); else System.out.println("金牛座"); break; case 5: if (day System.out.println("金牛座"); else System.out.println("双子座"); break; case 6: if (day System.out.println("双子座"); else System.out.println("巨蟹座"); break; case 7: if (day System.out.println("巨蟹座"); else System.out.println("狮子座"); break; case 8: if (day System.out.println("狮子座"); else System.out.println("处女座"); break; case 9: if (day System.out.println("处女座"); else System.out.println("天枰座"); break; case 10: if (day System.out.println("天枰座"); else System.out.println("天蝎座"); break; case 11: if (day System.out.println("天蝎座"); else System.out.println("射手座"); break; case 12: if (day System.out.println("射手座"); else System.out.println("摩羯座"); } } }

用java 输入两个日期判断分别是什么星座

展开全部 /** * 根据月日判断星座 * @param month * @param day * @return int */ public static String getConstellation(int m,int d){ final String[] constellationArr = {"魔羯座" ,"水瓶座", "双鱼座", "牡羊座", "金牛座", "双子座", "巨蟹座", "狮子座", "处女座", "天秤座","天蝎座", "射手座", "魔羯座" }; final int[] constellationEdgeDay = { 20,18,20,20,20,21,22,22,22,22,21,21}; int month=m; int day =d; if (day = 0) { return constellationArr[month]; } //default to return 魔羯 return constellationArr[11]; }...

用java编一个程序能通过用户输入的生日判断用户的星座。

请大神们给...
