Java method doesn't print out anything after running

Question

I'm making a little card game in java. Right now, I'm working on hand classifications. However, when I run the method 'handclassifier', I don't get anything. Here's an example of what eclispe outputs into the console:

Standard Output

Your hand: 6 of Spades, Queen of Spades
Creek: 10 of Spades, 9 of Spades, Queen of Clubs 
Current value: 

As you can see, the handclassifier method doesn't return anything at all, even when the requirement for a pair is met. I have it run after the first 2 methods so that the cards can load up and be classified by the method. Is there something wrong in the code for the comparisons?

Answer 1

while(stop = false) {

should be

while(!stop) { 

or

while(stop == false) {

You are assigning false to the stop variable instead of comparing its current value to false.
