1. a) Make a JAVA method that checks if an "element", within a collection, is located in a non-empty column. Return true if its located in a non-empty column and return false otherwise. Assume that the collection is a collection of strings and the element itself is a character.

b) Make another JAVA method that returns the contents of the non-empty column where the passed "element" from part a) is from.

For both questions use an ArrayList to represent the collection
