java构造函数的问题

Question

package work3; import java.util.Scanner; public class chengji {     /**      * @param args      */     public enum grade{         a(90),         b(80),         c(70),         d(60),         e(0);              private int score;          private grade(int score){         this.score=score;     }     public int getscore(){         return this.score;     }      }          public static void main(String[] args) {         // TODO Auto-generated method stub         Scanner sc=new Scanner(System.in);         System.out.println("请输入十个数字:");         int a[]=new int [10];         int b[]=new int [5];                 for(int i=0;i<10;i++){             grade g1 = new grade(a[i]);             a[i]=sc.nextInt();             if(a[i]>g1.a.getscore())             {                 b[0]++;             }             else if(a[i]>g1.b.getscore())             {                 b[1]++;             }             else if(a[i]>g1.c.getscore())             {                 b[2]++;             }             else if(a[i]>g1.d.getscore())             {                 b[3]++;             }             else{                 b[4]++;             }         }       }     }怎么调用构造函数传值进去进行初始化啊，我总是出错，我用grade g1=new grade(a[i])初始化就提示不能实例化类型 chengji.grade
