These exercises are missing the important thing which is asking the user to input. (Print the question)

Task was not quite clear, I think you should remove second requirement and add in the end new requirement that only final number should be displayed.

Requirement #2 is not clear. It says that first should be displayed the entered number, not the result. If you do that, verifying wouldn't pass. Please change the requirement text to be non-ambiguous.

I created a "reader" object to name things in the object. It's built from the BufferReader 'stuff' provided by Java to use. Acquire the input variable then manipulate it. I started to scribble out some logic code described in the Tasks. It sounded like if / else could be used ... and we are in Level 3. Hints: the number needs to be greater > than 0 - if so x2 --- if negative number plus one
