我构建java程序是作为uni分配的一部分，作为提交的一部分，它必须能够在DOS窗口（读取Windows命令窗口）中编译和运行。该程序在Netbeans中运行良好，但当我将所有.java文件复制到一个单独的文件夹中并尝试编译每个文件时，会出现大量编译错误。当我在Netbeans中创建这些文件时，我将它们都作为一个包的一部分，并让Netbeans在每个类的顶部添加一个“package*Project_Name*”。剩下的是标准java，没有什么太复杂的。这是我第一次使用Netbeans（我使用的是7.1.1版），它让我发疯。我可以创建一个.jar文件，并且可以从命令行运行它，但是我需要能够显示源代码可以从命令行编译，并且生成的文件也可以从命令行运行。是否有其他人有过这个问题，如果有，您是如何克服的，或者是否有人知道如何解决这个问题

我觉得这与对其他文件的引用有关，因为大多数错误都与创建的对象和从其他文件调用的方法有关。对于exmaple，我有一个Manager.java文件，其中包含一个Manager对象的构造函数和方法，然后在另一个文件（比如Proprety.java）中，我有使用new关键字创建Manager对象的代码

我使用的当前类路径为

类路径=。；C:\ProgramFiles\java\jdk1.7.0\U 03\lib；C:\ProgramFiles\Java\jre6\lib\ext\QTJava.zip

PATH变量的设置如下

。。。；C:\ProgramFiles\Java\jdk1.7.0\U 03\bin；C:\ProgramFiles\Java\jre7\bin

就这样。我使用的唯一库是java.util.*和java.io.*所有其他引用都指向我在Netbeans中创建的类文件

任何帮助都会被感激的

提前谢谢

好的，我想，关键是：

我让它们都成为一个包的一部分，并让Netbeans在每个类的顶部添加一个“package*Project_Name*”

以及您要编译的命令：

javacmanager.java

假设您的包名为

projectname

。然后Netbeans创建了一个目录

projectname

，并将所有Java文件

Manager.Java

、

Property.Java

，等等放在其中

在Java中，包结构直接对应于文件系统中的目录结构。例如，如果包

x.y.z

中有一个类

，则类

的源代码文件位于文件

x\y\z\a.java

中

因此，当您复制所有

*.java

文件时，您必须确保同时复制原始目录结构。在您的情况下，您可以复制类

Manager.java

，

Property.java

。。。到

C:\test\projectname

。然后在您的DOS盒

cd

中转到该目录，并使用以下内容编译您的类：

javac -cp .. Manager.java

-cp..

命令行选项的含义是，包/目录结构的根在

C:\test

上一级。然后，在编译

Manager.java

时，java编译器会找到对class

Property

的引用，并假定class

Property

与class

Manager

位于同一个包中。因此，编译器正在查找类

projectname.Property

。使用指向

C:\est

，编译器知道它应该查找目录

C:\test\projectname

编译后，您可以使用以下工具运行程序：

java -cp .. projectname.Manager

您是否设置了适当的类路径？您并没有提供任何我们可以用来帮助您的实际信息。您应该包括一些关于所用类的基本信息。您是否设置了正确的类路径？您使用库吗？我试图编译的文件位于C:\Estatement中。我使用的库是java.util和java.io。其余的是我自己创建的类。如果发布正在运行的命令和得到的输出，可能会有所帮助。
