Hi I need help with my Java assignment, thanks in advance.

You are going to write a method to be called 'validateBoard") that is going to validate whether or not a Tic-Tac-Toe board is possible. Tic-Tac-Toe is played on a 3 by 3 board and players take turns placing either an x or an o on the board. We will assume that in Tic-Tac-Toe, the player placing x will go first and that o will go second. Learn more about the game here: https://en.wikipedia.org/wiki/Tic-tac-toe As the player placing x pieces goes first, and play alternates, a valid board is one in which there is either the same number or one more x game pieces on the board as there are o game pieces. The board is represented by a 3 by 3 array that holds strings that represent the game piece at each location. A space can hold any of the following: "X", representing an x game piece in that position "O", representing an o game piece in that position .".", representing an empty position on the board Write the body of the program. Details The main method of the program has been completed for you. You are to create the method called 'validateBoard' which is called from the main method. The validateBoard" method should take a 2D array as input and return a boolean value. Details of this method are below: Input The validateBoard method should take as input: - a 2-dimensional array that holds strings (representing the 3 by 3 game board where strings "x", "o" and "." denoting the game piece in each location, as described above) Processing The new method will decide whether the incoming 2D array is represents a valid board. A valid board is defined to be a board in which there are either the same number of xas o game pieces, or one more x than o. Output If the board is determined to be valid, the method will return a boolean value of true. Otherwise, it will return false. Sample input/output: Sample Input Sample output {"x", ".", "."},{"x",".","x"}, {"x","0","0"} true {"x","0","."}, {"x",".","."}, {"x","0","0"} true {"x","x","."},{"x",".","."},{"x","0","0"} false 6- import java.util.*; 8- public class POD { /** * Validates that a 3x3 Tic-Tac-Toe game board is a valid board. * i.e. a board that has at most one more x than o on it. * @param gameBoard String[3][3] that holds game board info * @return True if valid board, false otherwise. public static boolean validateBoard(String[][] gameBoard) { boolean validBoard; //PLEASE START YOUR WORK HERE //PLEASE END YOUR WORK HERE return (validBoard); public static void main(String[] args) { //Instantiate new scanner to read from the console.
