Before you can run the code, you'll need to compile it. Calling javac with the path to the file will do this:

javac D:\Add.java\Add.java

Then you can call java on the .class file that was generated (without the .class extension):

java Add

If you call java outside the directory the .class file is in, you'll need to specify the path with the classpath option:

java -cp D:\Add.java Add

I'd recommend not adding the file extension in the directory name, as it causes confusion to what you're actually referring to.

You need to add the classpath option (like in the last example) since you're calling from C:\Documents and Settings\sone
