This should be done as a beginner, and in a formula similar to this :

Main topics: User validated input Basic String Methods if & if - else Statements Loop Statements Program Specification: Write a Java program that playes a simple game of Tic-Tac-Toe: . This is a two player (X's and O's) board game. . The game board is a 3 X 3 grid, where each location can hold either an 'X' an ,O, or a space (empty) Note: we will linearize the grid and refer to the its locations as 1 - 9, for conveyance . The players take turns placing their mark into one of the (empty) locations in the grid The game is won when a player has their mark in all three locations of any row, column, or diagonal The game can also reach a stalemate: neither player has won (by above criteria) however there are no more empty locations in the grid Requirement(s) . You must use an appropriate user-validation loop for all user input. Hint(s): . Use nine char variables (initialized to ' ') to represent the 9 grid location:s Keep track of the total number of moves, for an easy stalemate detection . Your location choice user-validation loop must also not accept any location that is not currently empty . At times things will feel very tedious - doing the "same" thing nine times
