Compiling java code from the command line
 

This has been frustrating me intensely.

I am trying to compile my source code from the Windows 7 command prompt. I have added the directory in which my *.java file is located to the classpath. Yet, I still get this error:

C:\Users\Alex>javac HelloThere.java
javac: file not found: HelloThere.java
Usage: javac <options> <source files>
use -help for a list of possible options

I'm very confused as to why this happens because if I navigate to the folder where this file is located, it will compile. However, this is not a satisfactory solution since I intend on compiling JUnit tests directly from the command line as well...

Other solutions I have attempted:

C:\Users\Alex>javac -classpath "C:\Users\Alex\AndroidProject\UnitTest\src" Hello
There.java
javac: file not found: HelloThere.java
Usage: javac <options> <source files>
use -help for a list of possible options

I do not think this has ANYTHING to do with typos...

Please tell me I'm just doing something stupid...because I have no idea why this will not work...

Yes it is the right way of compiling java program. "javac" command will try to find the file in the same directory where you execute the command.
And you can specify classpath option when you run the program.

I have the same problem. I need to figure this out for an exam. Why does the classpath option on the command line not find my .java file???
