问题 I am new to Java, started learning swing and have a problem with resizing a JPanel inside a JFrame. I am following this tutorial: http://vincentramdhanie.blogspot.com/2009/11/cardlayout-with-netbeans.html because ultimately I am learning each of the different layouts and have come to the CardLayout now.

问题 I've posted my code below. I have the simple task of creating a navigable GUI. I've spent the past few hours doing research on how to accomplish this, and this is the code that I've put together. Originally I wanted to perform the navigation without any layouts or anything. I need the home panel to display after the user clicks on the "login" button on the welcome panel.
