java - JAVA 一直报错

Question

我不断收到此错误:

Exception in thread "main" java.lang.Error: Unresolved compilation problem: 
at test.apples.main(apples.java:6)

我的代码是:

import java.util.Random;

class apples {
    public static void main(String args[]) { 
          Random rand = new Random();
          int freq[]=new int[7];

          for(int roll=1;roll<1000;roll++) {
              ++freq[1+rand.nextInt(6)];

          }

          System.out.println("Face\tFrequency");

          for(int face=1;face<freq.length;face++) {
              System.out.println(face+"\t" +freq[face]);
          }
       }
    }

您必须在类顶部添加package test;，然后清理并重建代码。
