    Default Array table question

    import javax.swing.JOptionPane;
     
     
    public class circle{
      //Instance variables
      /*
       * 2D array of chars for the board
       */
     
    	public static void main(String[] args)
    	{
    		circle o = new circle();
    		o.print();
     
     
     
     
    	}
     
     
      private char[][] board;
     
      /** 
       * Creates a board where each
       * square holds the underline '_' character.
       */
      public circle(){
        board = new char[2][3];
        for (int row = 0; row < 2; row ++){
          for (int col =  0; col < 3; col++){
            board[row][col] = '_';
          } // end of inner loop
        } // end of outer loop
      } 
     
     
      public char get(int row, int col){
        return board[row][col];
      }
     
     
     
     
      public void print(){
        int col;
        System.out.println();
        for (int row = 0; row < 2; row ++){
          if(row == 0){
            System.out.print("Start"+ "\t");
          }
          else {
            System.out.print("Finish"+ "\t");
          }
          for (col =  0; col < 3; col++){
            System.out.print(board[row][col] + " ");
          } // end of inner loop
          System.out.println();
        } // end of outer loop   
      }
    }

    This prints:
    Start _ _ _
    Finish _ _ _


    I was wondering how i could change the "_" to "X" if the user inputs a correct answer :S

    how i could change the "_" to "X"
    Find Where is the "_" stored and change its value to "X" when the user inputs a correct answer.

    I don't see where the user's answers are received or how they are related to the array that holds the "_"s.
    If you don't understand my answer, don't ignore it, ask a question.
