使用查找表法求星期和月份

提要：使用String来进行月份数组化，再进行选择
实现代码：

public class Test {
    public static void main(String[] args) {    
         System.out.println(week(6));
         System.out.println(week(9));//健壮性检验
         System.out.println(month(6));
         System.out.println(month(19));//健壮性检验
    }
     public static String week(int num){//求星期的函数
         String[] week={"","Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"};
         if(num<1||num>7)
             return "输入错误";
         return week[num];
     }
     public static String month(int num){//求月份的函数
         String[] month={"","January","February","March","April","May","June","July","August","September","October","November","December"};
         if(num<1||num>12)
             return "输入有误";
         return month[num];
     }
}
