Odd behaviour with key listener

Hi guys

Ok, this is my key listener:

Java Code:

 public class move extends KeyAdapter
    {
        int pos;
        public void keyPressed (KeyEvent k)
        {
           
            if(k.getKeyCode() ==  KeyEvent.VK_UP)
            {
               pos++;
            }
             if (k.getKeyCode() == KeyEvent.VK_DOWN);
            {
                pos--;

            }
             System.out.println(pos);
        }

    }

But the output is as follows:

0
0
0
-1
-2
-3

So when I press the up arrow, the value of pos is 0, but when I press down it correctly decreases the value of pos. I'm not sure why. Anybody got any hints?

Thanks

Ok, sorry for wasting your time. I figured it out. Wish I could mark this solved

Java Code:

 public class move extends KeyAdapter
    {
        int pos;
        public void keyPressed (KeyEvent k)
        {
           
            if(k.getKeyCode() ==  KeyEvent.VK_UP)
            {
               pos++;

               System.out.println(pos);
            }
        else
            {
                if(k.getKeyCode() == KeyEvent.VK_DOWN);
            {
                pos--;
                System.out.println(pos);

            }
                
            }
                        
        }
    }
