infamous tictactoe program...

[_inase]

I'm making a tic-tac-toe program, but I have two issues. First, the code compiles and runs, but the while loop in main never stops. I suppose it's not checking for a winner correctly but I'm unsure how to fix it. Also, how do I get the display board to display the 'X' or 'O' after each input?

Main

import java.util.Scanner;

public class Assignment2 {

	public static void main(String[] args) {
		
		Scanner in = new Scanner(System.in);
		System.out.println("Welcome to Tic-Tac-Toe");

		TicTacToe game = new TicTacToe();
		
		int row;
		int col;
		
		while(game.findWinner() == ' ' || game.boardFull()){
			
			game.boardDisplay();
			
			System.out.print(game.currentPlayer() + " choose a row, 0-2: ");
			row = in.nextInt();
	
			if(row < 0 || row > 2){
				System.out.print("Invalid. Try again.");
				row = in.nextInt();}
			
			System.out.print("Choose a column, 0-2: ");
			col = in.nextInt();
			
			if(col < 0 || col > 2){
				System.out.print("Invalid. Try again.");
				col = in.nextInt();}
			
			while(game.setMove(row, col)){
				System.out.print("Space taken, try again, choose row 0-2: ");
				row = in.nextInt();
				System.out.print("Choose column: ");
				col = in.nextInt();
			}
			
			System.out.print(game.switchPlayer() + " choose a row, 0-2: ");
			row = in.nextInt();
			
			if(row < 0 || row > 2){
				System.out.print("Invalid. Try again.");
				row = in.nextInt();}
			
			System.out.print("Choose a column, 0-2: ");
			col = in.nextInt();
			
			if(col < 0 || col > 2){
				System.out.print("Invalid. Try again.");
				row = in.nextInt();}
			
			while(game.setMove(row, col)){
				System.out.print("Space taken, try again, choose row 0-2: ");
				row = in.nextInt();
				System.out.print("Choose column: ");
				col = in.nextInt();
			}
		
			}
		
		if(game.boardFull() == true){
			System.out.print("It's a draw");
		}
		else{
		System.out.print(game.findWinner() + "WINS!");
		}
		
	}
}

I suppose it's not checking for a winner correctly

Sounds like time for some debugging. Add some printlns to your code to show the values of the variables that are being used to determine a winner. print them every time they are changed. If you know when there is a winner,then the print outs should show you when your logic is missing a winner so you can fix it.

how do I get the display board to display the 'X' or 'O' after each input?

Copy and paste there what your program displays for the board.
