I need to create a JAVA Class TicTacToe program. There are API doc of the class TicTacToe and TicTacToeApp.java which program control TicTacToe game play. Would you please tell me how to write the Java Class program. Thanks a lot!

TicTacToeApp Java Program as shown below:

/**
*   TIC TAC TOE App
*/
public class TicTacToeApp
{


/**
*   <div>The main method (Application Entry)
*   TicTacToeApps
*   </div>
*/
public static void main (String args[])
{
// print game title
System.out.println("TicTacToe Game");
// create a TicTacToe object
TicTacToe ttt = new TicTacToe();


// display the game board
ttt.display();


// while the game is not end
while (!ttt.isGameEnded())
{
// prompt player to make a move
System.out.print("Please make a move, Player ");
if (TicTacToe.PLAYER1 == ttt.getNextMovePlayer())
System.out.println("1:");
else
System.out.println("2:");


// read x and y coordinate
System.out.print("x: ");
int x = SavitchIn.readLineInt();
System.out.print("y: ");
int y = SavitchIn.readLineInt();


// make a move
if (!ttt.addMove(x ,y))
System.out.println(">>> Invalid Move, try again! <<<\n");


// display the game board
ttt.display();
}


// the game is ended
if (ttt.isGameEnded())
{
if (ttt.getWinner() != TicTacToe.NOPLAYER)
// there is a winner
if (ttt.getWinner() == TicTacToe.PLAYER1)
System.out.println("Winner is: player 1");
else
System.out.println("Winner is: player 2");
else
// the game drawn
System.out.println("Draw Game!");
}
}


}

Don't use a single massive monolith of a class. That way lies disaster.

For the rest, sit down and write a design. Doesn't have to be a lot, just put some thoughts onto paper how you're going to do this thing.
Then start your text editor and start writing Java (or better expand that design document until it starts to write the code for you).

We're NOT going to write your program for you, that's your job.

If you have specific details you're stuck on be free to ask for help of course, but "write my program" is NOT a good question to ask (it's not even a question, it's an order and you're not paying us).

I would suggest to use a 3x3 two dimensional array. Maybe something like

char player[][] = new char[3][3];

Then when player 1 wants to use cell (1,2) write:

player[1][2] = '1';
