That works fine for me, so there must be something different in your setup. Please edit your question and show the source of your Java file: just the relevant parts.

Fixed [I think] see above. It's the old "launch above the package" problem.

Well spotted, I didn't think of the com. part.

If you'r in the same folder as the Hamzah.class file, you can invoke it directly using:

java Hamzah

This assumes Hamzah has a valid main method.
Assuming your class is in package com.hamzah, build and run from the src directory:

C:\Users\h.khammash\Desktop\Studening workspace\TestCmd\src>javac com\hamzah\Hamzah.java
C:\Users\h.khammash\Desktop\Studening workspace\TestCmd\src>java com.hamzah.Hamzah
