Add a public class named FileManager to  that contains the following methods:
public static void writeToFile(String saveState, String fileName) {
    //TODO: a string to a new file synchronously
}

public static void writeToFileAsync (String saveState, String
    fileName) {
    //TODO: a string to a new file asynchronously
}
Implement the  writeToFile() method using a FileWriter in a try-with-resources block. Make sure to import the io package: import.java.io.*
Implement the  writeToFileAsync() method using a separate thread. Use the following code as a guide:
new Thread() {
    public void run(){    
        writeToFile(saveState fileName);
    }
}.start();
 

 

 

Part2.

 

In the main() method of the BoardGameTester project, add the following code:

FileManager.writeToFileAsync(ticTacToe.toString(),
    "ttt.txt");
FileManager.writeToFileAsync(connectFour.toString(),
    "c4.txt");
FileManager.writeToFileAsync(mastermind.toString(),
    "mm.txt");
 

BoardGameTester.java:

 

package games.boards;

 

import games.boards.*;

 

 

 

public class BoardGameTester {

 

public static void main(String[] args) {

// board for tictactoe

Board ticTacToeBoard = new Board(3, 3);

//board for Connect Four

Board connectFourBoard = new Board(6,7);

//board for Mastermind

Board mastermindBoard = new Board(5,8);

//cell to a nought or cross on the Tic-Tac-Toe board

ticTacToeBoard.setCell(Mark.NOUGHT, 0, 0);

ticTacToeBoard.setCell(Mark.CROSS, 1, 1);

//cell to yellow or red on the Connect Four board

connectFourBoard.setCell(Mark.YELLOW, 2, 3);

connectFourBoard.setCell(Mark.RED, 3, 4);

//cell to yellow, red, green, blue, magenta, or orange on the Mastermind board

mastermindBoard.setCell(Mark.YELLOW, 0, 0);

mastermindBoard.setCell(Mark.RED, 0, 1);

mastermindBoard.setCell(Mark.GREEN, 0, 2);

mastermindBoard.setCell(Mark.BLUE, 0, 3);

mastermindBoard.setCell(Mark.MAGENTA, 0, 4);

mastermindBoard.setCell(Mark.ORANGE, 0, 5);

//boards for Tic-Tac-Toe, Connect Four, and Mastermind

System.out.println("TicTacToe board:");

System.out.println(ticTacToeBoard);

 

System.out.println("Connect four board:");

System.out.println(connectFourBoard);

 

System.out.println("Mastermind board:");

System.out.println(mastermindBoard);

 

}

 

}

 

 

 

 

The first argument in each method call should have the name used for the corresponding Board object. Remember to import the games.utilities package!
