源碼如下:
Scanner sv = new Scanner(System.in);
System.out.print("請輸入月份(1-12):");
int c = sv.nextInt();
switch (c) {
case 1:
case 2:
case 12:
System.out.println(c + "月是冬季!");
break;
case 3:
case 4:
case 5:
System.out.println(c + "月是春季!");
break;
case 6:
case 7:
case 8:
System.out.println(c + "月是夏季!");
break;
case 9:
case 10:
case 11:
System.out.println(c + "月是秋季!");
break;
default:
System.out.println(c + "是什麼呀!你的輸入有誤!要輸入1-12的數字喲!");
sv.nextLine();
}
