getContentPane().setLayout(null); This looks wrong. A setLayout() function ususally wants a type of layout as an argument, and I wouldn't be surprised if passing it null is causing the exception.

You initialize speed: ``` JSlider speed; //Speed of ball ``` So at this point it is null. Later on you call: ``` speed.setBounds(1, 1, 50, 50); ``` You are calling a method for a null value, which isn't possible. You need speed to be initialized. For example you would need something along the lines of `speed = new JSlider()` to ensure that it's a non-null object. Then you can call methods on it.
