无法静态引用非静态归档方法行17和9

Question

我正在尝试这样保存来自扫描仪的输入，但是我一直无法获取静态引用

  import java.util.Scanner;
    public class Month {
        //instance fields
        int number;
        //constructor methods
        private String names;
        public Month(String names){
        names = ("January February March April May June July August September October November December");
        }
        //main method
        public static void main(String[]args){
          System.out.println("Enter number from 1 - 12: ");
          Scanner one = new Scanner (System.in);
            number=one.nextdouble();  
        }      
    }
