Answer 1

Martin Taylor Thanks for the help!

Answer 2

Martin Taylor So we cannot work with chars using arraylists or vice versa? That would mean we cannot change the length of a char array, right?

Martin Taylor Apparently there's still one more error at line 9, "unexpected type". Why is that?

Answer 4

Nevermind, I just found out how to turn char into character (primitive data into class).
