title: (Java) Appearing/Disappearing JLabel in a JPanel only disappears on resize
body: <p>I'm working in Java, and I have a JPanel in a JFrame. In that JPanel, among other things, I have a JLabel that I want to make appear and disappear at will. I've tried setting visibility to true/false, adding and removing it from the JFrame and JPanel, and, having looked online, I tried validate()ing and revalidate()ing ad infinitum. What can be done here to solve this problem?</p>
