classpath错误 [英] classpath error
问题描述
嘿所有我是一个初学java用户，我得到一个与我认为的类路径有关的错误。
我有一个文件JM550b.java，它试图访问类QTCycle时编译。 QTCycle.java创建一个名为jmqt" package jmqt;"的软件包。并且该类被放置在该文件夹中。
QTCycle.java成功编译但是当我尝试编译JM550b.java时，我收到一条错误，上面写着无法访问QTCycle。在线私人静态QTCycle播放器;
它还说
无法访问QTCycle
坏类文件：C：\Documents and Settings \Rachael \Desktop \Dom\Tutorial\jmqt\QTCycle .class
类文件包含错误的类：jmqt.QTCycle
请删除或确保它出现在类路径的正确子目录中。
私有静态QTCycle播放器;"
我的目录是这样的:(我确定这是出现问题的地方，请帮我解决这个问题！）
桌面\ DomD！\\ Tutorial \ src - 这是主要的.java我的项目的文件保存，因为主程序将访问几个类。
Desktop \Dom \Tutorial \ _jmqt - 这是QTCycle类在编译时所用的地方
我不确定我还需要说什么，但如果有人可以提供帮助，我会很高兴能提供所有信息。
请帮助！
hey all im a beginner java user and am getting an error relating to the classpath i assume.
I have a file JM550b.java which is trying to access the class QTCycle when compiling. QTCycle.java creates a package called jmqt "package jmqt;" and the class is placed in that folder.
QTCycle.java compiles successfuly but when i try to compile JM550b.java i get an error saying "cannot access QTCycle" on the line "private static QTCycle player;"
It also says
"cannot access QTCycle
bad class file: C:\Documents and Settings\Rachael\Desktop\Dom\Tutorial\jmqt\QTCycle .class
class file contains wrong class: jmqt.QTCycle
Please remove or make sure it appears in the correct subdirectory of the classpath.
private static QTCycle player;"
My directory is like this: (im sure this is where the problems arise please help me im struggling with this!)
Desktop\Dom\Tutorial\src - this is where the main .java files of my project are kept as there a few classes the main program will access.
Desktop\Dom\Tutorial\jmqt - this is where the QTCycle class goes when it is compiled
Im not sure what more i need to say but if anyone can help i will be glad to give all info i can.
Please help!
推荐答案
您的第一个错误是由尝试从其他类访问私有字段引起的。这是不允许的。
Your first error is caused by trying to access a private field from nother class. That''s not allowed.

但是我有其他类似的行，例如私人静态按钮开始，停止;
和私有静态EightBeat1拍;"
这两个工作正常。
感谢您的回复：）
But i have other lines similar such as "private static Button start, stop;"
and "private static EightBeat1 pat;"
These two work fine.
Thank you for reply :)
I现在看，我不明白你的初始陈述，对不起。
它应该是一个目录结构问题。您的jmqt文件夹必须位于src文件夹中。
I see now that I did not understand your initial statements, sorry.
It should be a directory structure problem. Your jmqt folder must be in the src folder.
