4. Check the winner
Displaying a Winner
Write a method
getWinner(String curBoard) that returns the winner in a
String with an
array input of the current game board.
- If the player wins, return
"Congratulations! \nYou won the Game :)".
- If the computer wins, return
"Game Over! \nYou lost the Game :(".
- If there’s a tie, return
"It's a TIE! Try again".
- If there isn’t a winner yet, return
There are several ways to write this method.
Give it a try in the following repl.it first; it will tell you if your method is correctly written!
Ideas/Hints for writing the method
Stringsat the 3 positions that consist a horizontal, vertical, or diagonal row.
equals()to check if each of the concatenated Strings is
"OOO"for a winner. (You can even create another method that checks if an input
- If all the spots in the array is filled (a
for loopcan be helpful) and there is no winner, the game ends in a tie.
Calling the Winner Method
main(), call the method
getWinner() after the line of code where you place the player’s move,
Check if the game should continue (when there is no winner or a tie).
If there is a winner or a tie, print out the final board and the game result! And, add the line of code
break;, which prompts the program to break out from the
Repeat Step Above
main(), repeat the code in the previous step (check winner and print result if needed) after you place the computer’s move,
Close the Scanner Object
Outside of the while loop, add the code
sc.close() to close the
Scanner object from reading any new inputs.
It is good practice to close the
Scanner object if we won’t be getting any more inputs after we
break from the
All Done :) !
You should now have a functioning TicTacToe game! You should be so proud of yourself for finishing this workshop! Good Job 👍!
