If checking the rows for win does not return true then check the columns for win, etc. checkForWin() will be our main function to test all 3 of these functions for each scenario that the user input has affected.įor checkForWin() method: You simply need a return statement that calls upon the three different functions. Computers have to separate these into different conditions because they are all different in terms of arrays. There are three different functions to check for a win: rows, columns, and diagonals. The second attached image shows an example of what the described print function might look like. The only thing left is to print the last call to print the new line to separate each row, followed by the 13 dashes. To do this, we’ll print the character at that row and column using board (i being the variable used for the outer for loop, which was the row, and j being the variable used for the inner loop, which is the column.) This print statement will also contain a concatenated | character, to separate the boxes. Since our outer for loop already printed the first | character of each row of the board, we can go ahead to print the character that belongs in the box. Our inner for loop will also only loop through three columns. This loop will contain a call to print a '|' character, another for loop to loop through the columns, and a call to the () function to print a new line and the next 13 dashes to the screen. Below that, we need a for loop that will loop through each of the three rows. Because we are dealing with a 2D array, this will be handled with nested for loops.įirst, we just need to print a line of dashes (13 of them in this case) designating the top of the board. To print the board we must access every place in the 2D array named board in our TTT class. It will be handled in the method public void printBoard(), which is located in the TTT class. The initial printed board will look like the first image. The compiler is simply expecting for a value to be returned for all non-void methods.

Note: If you code method stubs for all of the method headers into your TTT class, your compiler will likely inform you that your code has errors. This method will check the three specified characters taken in to see if all three are the same ‘x’ or ‘o’ letter. Private boolean checkRowCol(char c1, char c2, char c3) This method will specifically check the diagonals for a win. This method will specifically check the columns for a win. This method will specifically check the rows for a win. This method will check to see if a player has won, and if so, it will return true.

It will return true if the board is full and a false otherwise. This method will check whether or not the board is full. This method will print the Tic-Tac-Toe board to standard output. This method will initialize the board variable such that all slots are empty. It will be responsible for ensuring the board gets initialized properly, and for setting who the first player will be. These behaviours are necessary for playing a full game of Tic-Tac-Toe. Each one has a short description of what the method will do under it. These methods will act upon the member variables of the TTT class to make the game of Tic-Tac-Toe mutable. Below are all of the method headers for the methods that belong inside of the TTT class.
The following is a general setup of the program. Below is a sample of what a game will play like. The input that will be taken in to specify where to place a mark will be in the format of two integers, which specify the row and column where the mark is to be placed. That process will be continued until one player wins or the board is filled up (indicating that a tie occurred). After placing the mark, we will print the board state again and then ask the other player for their move. Our Tic-Tac-Toe will start out by printing the board, and then asking for input from the first player that will specify where on the board to place that player’s mark. For this tutorial, we will be coding a text-based version of Tic-Tac-Toe. General Outline: There are many ways to implement a game of Tic-Tac-Toe in Java, so before we begin coding, we must think about how we will implement the game specifically. This tutorial assumes that you have knowledge of the basic syntax of Java, and access to a working Java compiler.

In this tutorial, we will be looking at how to code a working game of Tic-Tac-Toe in Java. Because of these things, Tic-Tac-Toe is fairly easy to code up. The rules of the game are simple and well-known.
Tic-Tac-Toe is a very common game that is fairly easy to play.
