Help with Java Pong Game

[triggerthat]

Hi guys,

Am abit stuck with some logic. Basically if the ball hits the walls it will change direction obviously. However, I can't get get the ball to change direction when the ball hits the paddle.

if(inPlay)
{
		if( (x==0) || (x== getWidth() - size) || (x>box.getWidth()+batWidth && x<box.getWidth()+batWidth)  )
		{
			xd *= -1;
		}
		if( (y==20) || (y == getHeight() - size) ||  (y>box.getHeight()+batWidth && y<box.getHeight()+batWidth)    )
		{
			yd *= -1;
		}
			x+= xd;
			y += yd;
}

Something like this? I've tried it, but it doesn't like..

((x > box.getWidth() - batWidth - getWidth()/9) && (x < box.getWidth() - batWidth))

((y > box.getHeight() - batHeight - getHeight()/9) && (y < box.getHeight() - getHeight()/9)
