Basic Tic Tac Toe in java

I am trying to make a simple tic tac toe game in java and i'm almost done but my program doesn't declare a winner and doesn't declare if the game is a draw or not even when in my code i told it to declare a winner.

Here is my code:

 import java.util.*;

 public class TicTacToe {

/**
 * @param args the command line arguments
 */
    public  static int row,colm;
public  static char board[][]=new char [3][4];
public static Scanner console=new Scanner(System.in);
public static char turn='X';

public static void main(String[] args) {
 for(int i=0;i<3;i++){
     for(int j=0;j<4;j++){
         board[i][j]='_';
     }

}
 board();
 play();
 winner(row,colm);



 }
  public static void board(){
  for(int i=0;i<3;i++){


    for(int j=0;j<4;j++){
        if(j==0){
            System.out.print("|");
        }else{

        System.out.print(board[i][j]+"|");
    }

}
    System.out.println();



 }}


 public static void play(){
boolean playing=true;
while(playing){
  row=console.nextInt();
  colm=console.nextInt();
  board[row][colm]=turn;


  if(winner(row,colm)){
      playing=false;
      System.out.print("you win");
  }
   board();
  if(turn=='X'){
      System.out.println("Player 2 your O");
      turn='O';
  }else
      turn='X';


  }
 }
  public static boolean  winner(int move1,int move2){
 if(board[0][move2]==board[1][move2]&&board[0][move2]==board[2][move2])
 return true;

if(board[move1][0]==board[move1][1]&&board[move1][0]==board[move1][2])
    return true;
 if(board[0][0]==board[1][1]&&board[0][0]==board[2][2]&&board[1][1]!='_')
return true;

if(board[0][2]==board[1][1]&&board[0][2]==board[2][0]&board[1][1]!='_')
return true;
return false;
