    9. You use a nested loop, if that's what you meant by double then yes.

    <outer loop condition>

    {

        <inner loop condition>

        {

        // like this

        }

    }

    10. True.

    12. True.

    19. False *

    20. False *

    * Private fields and private methods are private to a class - period. Protected fields and protected methods are fields and methods that descendant classes can inherit and use, they are considered part of both classes, just like public fields and methods except only descendants can access protected fields and methods whereas anything can access a public field or method.

    9. It's not strictly necessary, but generally speaking, yes.

    10. Absolutely.

    12. That looks right.

    19. Not last I heard.

    20. I'm not sure what this means, is it asking something different from (19)?
