Java: Console Tic Tac Toe

This could have been done with arrays, but I had to do a project for school with if statements.

The class-


public class TicClass

{

	private int playerTurn;

	private char playerMarker;


	public TicClass()

	{

		playerTurn = 1;

                playerMarker = ' ';   

	}


	public char playerMarker() //Player assignments.

	{

		if(playerTurn == 1)

		{

			playerMarker = 'X';

			return 'X';

		}

		else

		{

			playerMarker = 'O';

			return 'O';

		}


	}


	public int getPlayer()

	{

		return playerTurn;

	}


	public void swapPlayers()

	{

		if(playerTurn == 1)

		{

			playerTurn = 2;

		}

		else

		{

			playerTurn = 1;

		}

	}

}

And the main class.


import javax.swing.JOptionPane;

public class Tic

	public static void main(String[] args)

	{

		int gameOver = 0;


		System.out.println("[" + one + "] [" + two + "] [" + three + "]");

		System.out.println("[" + four + "] [" + five + "] [" + six + "]");

		System.out.println("[" + seven + "] [" + eight + "] [" + nine + "]");
