Question

I’m new to Java and I need some help with 2D arrays.

In short, it’s a 4×4 grid where each player decides which position to obtain via input.

Player1 uses “1”, player2 uses “2”. The winner is the person who occupies 2×2.
E.g.

1 2 0 0
0 1 1 2
2 1 1 2
2 0 0 0

Player 1 wins in this case. I have no problem deciding who of the two wins, but I can’t implement a correct draw check. E.g

1 2 1 2
1 2 1 2
1 2 1 2

It’s a draw game because no player obtained 2×2 in the grid. However, I have no idea how to detect that without breaking something else. 🙁

Any help is much appreciated.

Answer 1

If you know how to detect a winner there shouldn’t be a problem detecting if the game ended in a draw:

1. look for a winner
2. no winner found? It’s a draw.
