java代码如何根据月份日期计算出星座信息呢?

实现思路:
    1.获取出生日期的月份和日期信息
	2.使用if语句进行判断,检测出其所在的星座信息

import java.util.Scanner;

public class TestConstellation { 
	public static void main(String[] args) {
		Scanner scanner = new Scanner(System.in);
		System.out.print("请输入出生月份：");
		int month = scanner.nextInt();
		System.out.print("请输入出生日期：");
		int day = scanner.nextInt();
 
		if ((month == 1 && day >= 20) || (month == 2 && day <= 18)) {
			System.out.println("生日" + month + "月" + day + "日是水瓶座");
		} else if ((month == 2 && day >= 19) || (month == 3 && day <= 20)) {
			System.out.println("生日" + month + "月" + day + "日是双鱼座");
		} else if ((month == 3 && day >= 21) || (month == 4 && day <= 19)) {
			System.out.println("生日" + month + "月" + day + "日是白羊座");
		} else if ((month == 4 && day >= 20) || (month == 5 && day <= 20)) {
			System.out.println("生日" + month + "月" + day + "日是金牛座");
		} else if ((month == 5 && day >= 21) || (month == 6 && day <= 21)) {
			System.out.println("生日" + month + "月" + day + "日是双子座");
		} else if ((month == 6 && day >= 22) || (month == 7 && day <= 22)) {
			System.out.println("生日" + month + "月" + day + "日是巨蟹座");
		} else if ((month == 7 && day >= 23) || (month == 8 && day <= 22)) {
			System.out.println("生日" + month + "月" + day + "日是狮子座");
		} else if ((month == 8 && day >= 23) || (month == 9 && day <= 22)) {
			System.out.println("生日" + month + "月" + day + "日是处女座");
		} else if ((month == 9 && day >= 23) || (month == 10 && day <= 23)) {
			System.out.println("生日" + month + "月" + day + "日是天平座");
		} else if ((month == 10 && day >= 24) || (month == 11 && day <= 22)) {
			System.out.println("生日" + month + "月" + day + "日是天蝎座");
		} else if ((month == 11 && day >= 23) || (month == 12 && day <= 21)) {
			System.out.println("生日" + month + "月" + day + "日是射手座");
		} else if ((month == 12 && day >= 22) || (month == 1 && day <= 19)) {
			System.out.println("生日" + month + "月" + day + "日是摩羯座");
		}
		scanner.close();
	}
