How to return data to a different method and obtaining that data in java?

Question

I am making a tic tac toe program. The program needs to be able to determine a winner or a tie. I am using a "check" method and calling it after someone inputs their moves. I'm sure it's just syntax that I don't remember and can't find in the internet but I don't know how to return data from one method to another. Also is my ,logic right for finding a tie?

 import javax.swing.JOptionPane;
    public class tictactoe
    {
        public static void main(String args[])//coordinates = row:column
        {        
            String grid[][] = new String [4][4];
            int w = 0;
            int j = 0;
            int z = 1;
            for(w = 1; w <= 3; w++)
            {
                for(j = 1; j <= 3; j++)
                {
                    grid[w][j] = "[]";
                }
            }
            JOptionPane.showMessageDialog(null,"WELCOME to Matt's Fun World of TIC TAC TOE");
            JOptionPane.showMessageDialog(null, "Find the number of the box " + "\n" + "that you would like to enter you symbol." + "\n" +"DO NOT MAKE A MOVE YET!");
           Board_Game(grid, w, j);
        }

To fix the issue with returning values, you could do this:

Change your method signature and let it return a boolean:

public static boolean check(String grid[][], String a, String b, String c,String d, String e, String f, String g, String h, String i) {
    boolean done = false;

    // ....
    // do the checking now, and set done to true if its done ;-)

    return done;

And then call your method like this:

done = check(grid, a, b, c, d, e, f, g, h, i);
