How can make an object move and down, but when the object is moving up it should be slower then when its coming down. (coming down should be faster)


// with these instance fields private int hiY; // the higher y-limit private int, loY; // the lower y-limit private int speed; // the rate of movement // use this in act method if (speed == -1 && getY()<=hiY) speed = 2; if (speed == 2 && getY()>=loY) speed = -1; setLocation(getX(), getY()+speed;
