（基礎二）java if語句學習

public class IFTest {

    public static void main(String[] args) {
        //需求1：根據定義的數據，打印對應的星期的英文

/*      int x = 6;

        if(x == 1){
            System.out.println("Monday");
        }else if(x == 2){
            System.out.println("Tuesday");
        }else if(x == 3){
            System.out.println("Wednesday");
        }else if(x == 4){
            System.out.println("Thursday");
        }else if(x == 5){
            System.out.println("Friday");
        }else if(x ==  6){
            System.out.println("Saturday");
        }else if(x == 7){
            System.out.println("Sunday");
        }else{
            System.out.println("輸入數據錯誤！");
        }*/

        //需求2：根據用於指定月份，打印該月份所屬的季節。
        //3,4,5 春季 6,7,8 夏季  9,10,11 秋季 12, 1, 2 冬季

        //方法一：
/*      int month = 6;

        if(month == 1 || month == 2 || month == 3)
        {
            System.out.println(month+"月份是春季");
        }else if(month == 4 || month == 5 || month == 6){
            System.out.println(month+"月份是夏季");
        }else if(month == 7 || month == 8 || month == 8){
            System.out.println(month+"月份是秋季");
        }else if(month == 10 || month == 11 || month == 12){
            System.out.println(month+"月份是冬季");
        }else{
            System.out.println("月份不存在！");
        }*/

        //方法二：
        int month = 6;

        if(month >= 1 && month <= 3){
            System.out.println(month+"月份是春季");
        }else if(month >= 4 && month <= 6){
            System.out.println(month+"月份是春季");
        }else if(month >= 7 && month <= 9){
            System.out.println(month+"月份是春季");
        }else if(month >= 10 && month <= 12){
            System.out.println(month+"月份是春季");
        }else{
            System.out.println("月份不存在");
        }
    }
}
