Question

Can someone design a Tic Tac Toe game in java in the simplest way you can? It should have

-the markers for the players are X and O

-2 players

-instructions on how to play the game in the start of the game

-show the Tic Tac Toe grid before asking each player for their input

-be on one java file

Thank you!!!!!!! This is for an intro class so please don't make it too complicated!
