Ch03. Converter should be mentioned

[dawncold]

I'm following book content but can not finish the demo, and I searched a lot, youtube videos, stackoverflow posts, etc, I don't know why the demo could do that without a converter, and finally I found a converter class here.

@dawncold Thanks for your mention, which has solved my problem.

@dawncold Same with me, after searching everywhere trying to solve String[] to List found the converter. But I'm still getting the null pointer exception. Any suggestions, I posted on stackoverflow as well?
