Get a list of combinations of lists' elements

Question

Suppose I have 3 lists: [\'q\',\'w\'], [\'a\',\'s\'], [\'z\',\'x\']. How to get a list of possible combinations out of these lists? So I get a list [[\'q\',\'a\',\'z\'],[\'q

Answer 1

up you can create an inner class with a constructor (Parameters ...) , so you can put a list of this class which handles all the combinations
