Answer 1

Welcome to SQA.

Instead of me investigating what happens in this particular case, I think it will be more helpful for this and similar questions to understand how to

• read stacktrace
• see an actual value of your variable (i.e., debug with System.out.println()).
• read from JavaDoc for Java API, what each exception means, e.g., NullPointerException.

That will be useful to you not only in this particular case but also in your further adventure with test automation and generally programming.

Another option is to pair with a programmer in your company or your city and learn from him or her. My experience is that watching how someone else investigating a problem is much better way to learn things than explaining that here. This is a classical example of tacit knowledge.
