Question: 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.

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 :

> 
> Exception in thread "main" java.lang.NoClassDefFoundError:
>  FileManagement/Main
> 
> 
> 

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.

Answer: 
Guys let's understand the syntax of it.

1. If class file is present in the Current Dir.

**java -cp . fileName**
2. If class file is present within the Dir. Go to the Parent Dir and enter below cmd.

**java -cp . dir1.dir2.dir3.fileName**
3. If there is a dependency on external jars then,

**java -cp .:./jarName1:./jarName2 fileName**

Hope this helps.
What is the package name of your class? If there is no package name, then most likely the solution is:

```
java -cp FileManagement Main

```
