Hi, I wrote this sample code for tictactoe game, all works except the function checkWinner that takes two parameters an ArrayList and currentPlayer to check for the winner. this function is called after each player turn to check for the winning clicked cells in tictactoe game. I do not know where the error is! Thank you in advance
