    Default trying to use hashtable in tic tac toe game

    Hey, I'm trying to use a hashtable to determine which player has won, but seems like its not working.
    My guess is that im using "player1.containsKey(1)" incorrectly. I figured that each button is linked to a number from 1 to 9 and so each time a button is clicked, its stored in that players hashtable, then it checks if that hash table contains button 1,2,3 and all the other combinations. Any advise? thanks.


     class EnlargeListener implements ActionListener {
     
     
     public void actionPerformed(ActionEvent e) {
     
    	 Object source = e.getSource();
     
    		int xxx = 1;
    		while(xxx <=9){
    			   if(source == btn[xxx] && turn <      10)     {
     
    			if ((turn  % 2 == 0)){
     
     
    				btn[xxx].setIcon(new ImageIcon(imagee));
    				player1.put(btn[xxx], btn[xxx]);
    				btn[xxx].setEnabled(false);
     
     
    				if(player1.containsKey(1) && player1.containsKey(2) && player1.containsKey(3)){
    					JOptionPane.showMessageDialog(null, "Player one won!"); 
    				}
    				if(player1.containsKey(1) && player1.containsKey(4) && player1.containsKey(7)){
    					JOptionPane.showMessageDialog(null, "Player one won!"); 
    				}
    				if(player1.containsKey(1) && player1.containsKey(5) && player1.containsKey(9)){
    					JOptionPane.showMessageDialog(null, "Player one won!"); 
    				}
    			}
     
    			else {
     
    				btn[xxx].setIcon(new ImageIcon(image));
    				player2.put(btn[xxx], btn[xxx]);
    				btn[xxx].setEnabled(false);
     
    			}
     
    			turn++;
    		}
    	xxx++;
     }
     
     
     
     
    	}

    using "player1.containsKey(1)" incorrectly
    Did you try writing a 5 line program that adds a key to a Hashtable and then calls containsKey() to see what happens?


    Also printing out the contents of the hashtables will help you see what the program is doing.
     System.out.println("p1="+player1);
    If you don't understand my answer, don't ignore it, ask a question.

    dude.....you are passing buttons as key and value....but searching for integer...
    also....i don't think while loop here can give you desired results...
    btw...why is panel p1 used??

    o ok thank for the info, o , I don't think p1 is used, originally the code was something else and I just changed it.
    Also while loops seems fine lets me select the 9 button and wont let me pick the same one more then once and stops after all 9 are pressed

    Hey, yea I think I have. What I did now was to change player1.put(btn[xxx], btn[xxx]); to player1.put(xxx, xxx); and seems to work. The message pops up when circle has selects the top 3 buttons
    thanks

    Why are you using a hashtable? You never use the saved value.
    For something as simple as tictactoe, an array of binary values would work.
    If you don't understand my answer, don't ignore it, ask a question.
