Java矩阵包含ArrayList元素

Question

I am writing a tictactoe game, I have 1 ArrayList<String> OFields (it's containing fields that O is owning like TOP_LEFT, CENTRE_RIGHT etc) and a

String[][] winComb={{"TOP_LEFT","TOP_CENTRE","TOP_RIGHT"}, {"CENTRE_LEFT","CENTRE_CENTRE","CENTRE_RIGHT"},
                    {"BOT_LEFT","BOT_CENTRE","BOT_RIGHT"}, {"TOP_LEFT","CENTRE_LEFT","BOT_LEFT"}, 
                    {"TOP_CENTRE","CENTRE_CENTRE","BOT_CENTRE"}, {"TOP_RIGHT","CENTRE_RIGHT","BOT_RIGHT"},
                    {"TOP_LEFT","CENTRE_CENTRE","BOT_RIGHT"}, {"TOP_RIGHT","CENTRE_CENTRE","BOT_LEFT"}};

I want to check, that OFields's elements contains winComb[1..8]

if(OFields.contains((winComb[0][0])) && OFields.contains(winComb[0][1]) && OFields.contains(winComb[0][2])){
                                        System.out.println("win");
                                    }

That's what i have, it's working for the first winComb element but it would be really messy if i write like this. How can i check that all OFields element is in winComb matrix?

Answer 1

You can use List#containsAll() :

static boolean win(List<String> oFields) {
    for (String[] positions : WIN_COMB) {
        if (oFields.containsAll(Arrays.asList(positions)))
            return true;
    }
    return false;
}

But sincerely saying, I agree with @Jägermeister that you should chose more appropriate class model for that.
