Tic-Tac-Toe Java Two Players

Question

Hey there, I need help on getting two players to mark on the board with X and O and to check if the squares are available while preventing the players from overwriting each other. I have an idea but can't think of it. I may need some help.

Here's my code: https://code.sololearn.com/c0qwVq7OjXsH/#java

Answer 1

//Need to check to see if the board is available and that two players can't overwrite the square

So, it depends. Are you going to check if there is already any winner?
Yes? Then you will just break your loop after check. - better idea

No? You are counting turns, so you can just brake it while(turn<9)

avoid overwriting - compare current provided coords with board value

//Need help with marking X or O on the board based on number

You have array "board" and variables "r,c", so you basically have everything you need to mark "O" or "X" .
