从命令行Linux运行Java程序 [英] Running Java Program from Command Line Linux
问题描述
我不是很有经验的java和这是驱动我疯了。我写了一个java程序 FileManagement ，我需要从命令行运行它。
I am not very experience with java and this is driving me crazy. I wrote a java program FileManagement and I need to run it from the command line.
命令行与 javac FileManagement / *。java 将创建该文件夹中的所有类，但当我尝试 java FileManagement.Main 它说：
I can compile it from the command line with javac FileManagement/*.java which will create all the classes in that folder but when I try java FileManagement.Main it says :
线程main中的异常java.lang.NoClassDefFoundError：
FileManagement / Main
Exception in thread "main" java.lang.NoClassDefFoundError: FileManagement/Main
事情是，我在远程计算机上尝试过同样的过程，它工作正常。
The thing is that I have tried this same procedure in a remote computer and it is working fine. It is not working on mine.
推荐答案
如果你的 Main 在 FileManagement 包中，然后尝试：
If your Main class is in a package called FileManagement, then try:
java -cp . FileManagement.Main
在 FileManagement 文件夹。
如果您的 Main 类不在包中（默认包），则 cd 到 FileManagement 文件夹，然后尝试：
If your Main class is not in a package (the default package) then cd to the FileManagement folder and try:
java -cp . Main
有关CLASSPATH的更多信息以及JRE如何查找类：
