java高手帮忙啊！！！

import java.util.*;

public class Month
{
public static void main(String[] args)
{
int m;
String month[]={"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"};
System.out.println("enter the month number: ");
Scanner scanner = new Scanner(System.in);
m = scanner.nextInt();
if (m >= 1 && m <= 12)
{
System.out.println(month[m - 1]);
}
else
{
System.out.println("Your Input is wrong");
}
}
}

先判断用户输入的是否为数字,如果不是数字,则提示用户输入错误
再判断用户输入的是否是1-12的数字,如果不是,则提示用户没有那个月份
