问题描述

我正在尝试编译Board.java，它与Hexagon.java位于同一个包（和目录）中，但我收到此错误：

I am trying to compile Board.java, which is in the same package (and directory) as Hexagon.java, but I get this error:

Board.java:12: cannot find symbol
symbol  : class Hexagon
location: class oadams_atroche.Board
    private Hexagon[][] tiles;

Board.java的前几行：

The first few lines of Board.java:

package oadams_atroche;

import java.util.LinkedList;
import java.util.Queue;
import java.io.PrintStream;

import p323.hex.*;

public class Board implements Piece{
>---//Fields
>---private int n;
>---private Hexagon[][] tiles;

Hexagon.java的前几行：

The first few lines of Hexagon.java:

package oadams_atroche;

import p323.hex.*;

public class Hexagon implements Piece{

我只是看不到我是什么做错了。有什么想法吗？

I just cannot see what I am doing wrong. Any ideas?

谢谢

推荐答案

我很确定你'从错误的目录中编译。 您应该从源根目录编译，而不是从oadams_atroches目录中编译。

I'm quite sure you're compiling from within the wrong directory. You should compile from the source root-directory, and not from within the oadams_atroches directory.

看看这个bash-session：

Have a look at this bash-session:

aioobe@r60:~/tmp/hex/oadams_atroche$ ls
Board.java  Hexagon.java
aioobe@r60:~/tmp/hex/oadams_atroche$ javac Board.java
Board.java:12: cannot find symbol
symbol  : class Hexagon
location: class oadams_atroche.Board
    private Hexagon[][] tiles;
            ^
1 error

如果我上去一个目录......

While if I go up one directory...

aioobe@r60:~/tmp/hex/oadams_atroche$ cd ..

...并编译：

aioobe@r60:~/tmp/hex$ javac oadams_atroche/Board.java
aioobe@r60:~/tmp/hex$
