Tic-tac-toe in Java

• This is a functional tic-tac-toe game in Java.
• All things will be explained when you run the code.
• Type the following code in your IDE

import java.util.Scanner;

public class tic_tac_toe {

public static void main(String[] args) {

String turn="";

Scanner scan=new Scanner(System.in);

System.out.println("Welcome to tic-tac-toe");

System.out.println("Now mark them like this:");

System.out.println("1 2 3");

System.out.println("4 5 6");

System.out.println("7 8 9");

System.out.println("You can tell me your turn by writing only the cell number(1-9), nothing else.");

System.out.println("Only legal play is allowed. You get error in wrong turns.");
