Where are these error and warning icons as a java resource?

Question

I\'ve got a custom tree cell renderer that I\'m using to render custom icons a JTree, and I really like the warning icon and the error icon that JOptionPane displays for bot

Answer 1

And if you want to know about all the icons and their names you can check out: UIManager Defaults

Answer 2

We use them too via:

UIManager.getIcon("OptionPane.errorIcon")

UIManager.getIcon("OptionPane.warningIcon")
