java - UVA 11854 中的编译错误

Question

这是实际问题的链接，here

我已多次提交代码，但每次都会出现编译错误。原始消息是

"Main.java:4: error: class Egypt is public, should be declared in a file named Egypt.java
public class Egypt {
       ^
1 error"

我不知道我哪里错了。我已经复制了以下问题的代码。请帮我解决这个代码:

import java.util.Scanner; 
import java.util.Arrays;

public class Egypt {

    public static void main(String[] args) {

        Scanner input = new Scanner(System.in);

        while (true){
             int[] arr = new int[3];
             for (int i = 0; i < 3; i++)
             arr[i] = input.nextInt();

             if((arr[0]+arr[1]+arr[2])==0)
                    return;
             Arrays.sort(arr);

             int d = (int)(Math.pow(arr[0],2) + Math.pow(arr[1], 2));

             if(Math.sqrt(d)==arr[2])
                System.out.println("right");
             else
                System.out.println("wrong");
        }
    }

}

来自Java specifications here ,

All programs must begin in a static main method in a Main class.

Do not use public classes: even Main must be non public to avoid compile error.

所以，我认为你必须使用

class Main
