I'm making a Tic Tac Toe program for class. I've constructed the table and everything in my program but I have a couple problems still. Here is my code in it's entirety.
import java.util.Scanner;
public class TicTacToe {
//These two variables are for placing the X's and O's in the TicTacToe table.
static int row;
static int col;
//This array is for the TicTacToe table.

//This is for ending the while statement that controls the game
static boolean continuePlaying = true;
static boolean exitProgram = false;
//This is for returning true when the user inputs a valid combination of numbers
static boolean validMove = true;
//This is for returning false when the user inputs an invalid combination of numbers
static boolean invalidMove = false;
//These will store the names for player 1 and 2
static String p1;
static String p2;
//This variable will change every turn to either p1 or p2 depending on who's turn it is. (This is a bad idea at the moment)
static String activePlayer;
//This variable is to count the number of games played
static int gamesCounter = 0;
//These two variables are to keep track of the wins each player has
static int p1Wins = 0;
static int p2Wins = 0;
static void clearTable(){
for(int i = 0; i < table.length; i++){
table[i][i] = ' ';
}
}
//This is my displayTable() method. This will show the table and the X's or O's each player has played
static void displayTable(){
System.out.println(" 0 1 2");
System.out.println("0[" + table[0][0] +"][" + table[0][1] +"][" + table[0][2] +"]");
System.out.println("1[" + table[1][0] +"][" + table[1][1] +"][" + table[1][2] +"]");

}
//This is my move(int row,int col) method. This will record the moves each player takes and insert X's or O's depending on which player
static boolean move(int row,int col) {
//This if statement will return false if the user enters in coordinates outside the 3x3 zone.
if (row > 2 || row < 0) {
System.out.println("Invalid move."); return false;
}

My question for you all today is. When I finish a game in my program and it asks if I want to play another game. I'll type Yes. And nothing will happen. I have to type Yes twice for it to move on to another game, and then when my "clearTable();" method kicks in, it only replaces the X's in my program and not the O's.
Can someone explain to me why it would not remove the O's from my program and the x's? My method makes perfect sense, to me anyway.
static void clearTable(){
for(int i = 0; i < table.length; i++){
table[i][i] = ' ';
}
}
It will loop until everything has ' ' in it. I'm not sure why it excludes O's right now though.
Another concern I have, is after I finish a game and I type "No" so my program exits. I will have to type "No" twice, and then it just displays my table again, the table won't be cleared either. This shouldn't be what happens. My program should print the statistics of the players and then quit. Any ideas?
