Hey guys! I'm doing another school project, bleh ._.

The method I need help on is called isFlush. It's a boolean that needs to determine whether the hand (subDeck) is a flush or not.

A flush contains five cards with the same suit. I want to know how to just check for suit and disregard rank. This is what I have so far below, the method I need help is the final one before main.

Where do you specify the suits? Or am I going blind in these early hours

edit: ah I see, 0-3
