We don’t need to return anything since the function is simply printing out the board. In order for our function to draw the board and print it out, do we need to pass a parameter into the function? Do we need to return anything? Hint: We need to pass in the board 2D array in order for the function to be able to print it. Step 3: Create a function that draws the board and prints it out like a 3x3 square. We store their input in a String called p1.ĭo the same for p2. Next, we print out a message asking the user to type in their name using (). Step 2: Ask the users for their names.įirst, we import the Scanner to help us get input from the user, by adding import to the top of our program. Inside both for loops, we can set board equal to a dash. Hint: We can use a nested for loop to iterate through each position on our board. Now we have to fill our board with dashes.

Hint: We can use the following line of code to make a 3x3 array of chars: char board = new char We need to make a 2D array of characters, which can be x, o, or. How do we do each of these steps? Step 1: Create a 3x3 array to represent the tic tac toe board and fill it with dashes. Create a function that checks if either player has won.Set the right position on the board to the proper symbol.Keep asking the user to enter a row and col until they are valid.Keep track of the player’s turn and what symbol they are using.Create a function that draws the board like a square.Create a Tic Tac Toe board and fill it with dashes.Once the player wins by getting 3 in a row, column, or diagonal, the program prints that player 1 or 2 has won and prints out the final board.If the position the player entered is “off the board” or already has an x or o on it, then our program notifies the player, who is prompted to enter another row and col.Each turn it asks either player 1 or player 2 to enter a row and col index which is where they want to place their x and o, and then the board is printed again with the x or o in the right spot.After asking us for our names, the program prints out a 3x3 board filled with dashes, signifying empty spots.You can also view my project solution code if you get stuck. Without further ado, let’s get started! Project DemoĬlick run to play the Tic Tac Toe Java game yourself below! Moreover, we learn how we can turn a commonly played game into code by learning to think like a programmer. Just using these core concepts, we can create a whole game of Tic Tac Toe from start to finish. Learning Outcomes Core concepts practiced: Coding experience in language: Beginner.This is a challenging project for Java coders familiar with basic concepts, and is also great practice for AP Computer Science students. Use a 2D array to make a Tic Tac Toe game - and practice using conditionals, loops, and functions!
