小白第一次发帖，胆战心惊

先贴代码：

package abc;
import java.util.Scanner;
class DigitsNO1{
	
	 public static void main(String[] args) {
		 Scanner stdIn = new Scanner(System.in);
		 
		 int retry;
		 do {
			 System.out.print("计算季节\n请输入月份:");
			 int num = stdIn.nextInt();
				 
				 switch (num)  {
				 case 3: 
				 case 4: 
				 case 5: System.out.println("春季");  break;
				 case 6: 
				 case 7: 
				 case 8: System.out.println("夏季");  break;
				 case 9: 
				 case 10: 
				 case 11: System.out.println("秋季");  break;
				 case 12: 
				 case 1: 
				 case 2: System.out.println("冬季");  break;
				 }
				 System.out.print("要重复一次吗？\n1yes/2no:");
				 retry = stdIn.nextInt();
		 }  while (retry==1);
 
	 }
}
