Hi all, I want to add a component into top-level container. In here, I use JFrame as top-level container. My understanding is there are 2 ways to do that.. 1. I use JFrame method getContentPane().add(component); 2. Because of JFrame is subclass of java.awt.Containter, I can use JFrame method add(component) directly.
Is it true? Are there performance effect between both?
