Why null layout and absolute positions are bad practice in Java Swing?

Done correctly the layout will place the components like you want. Secondly, when dynamically adding a

I cannot find anything on setBounds, what it is for, or what its function actually is. Could someone clear me up on this? Thanks so much! You can use setBounds(x, y, width, height) to specify the position and size of a GUI component if you set the layout to null . Then (x, y) is the coordinate of the upper-left corner of that component. setBounds is used to define the bounding rectangle of a component. This includes it's position and size. The is used in a number of places within the framework. It is used by the layout manager's to define the position and size of a component within it's parent
