How to Wrap Text in JOptionPane Error Messages for Better Readability?

Incorporating Text Wrapping in JOptionPane Error Messages

When displaying error messages in Swing applications, the default behavior of JOptionPane can result in lengthy error dialogs that can be difficult to read. To address this issue, consider incorporating text wrapping to enhance the message presentation.

Solution: Utilizing HTML and CSS

JOptionPane utilizes a JLabel by default for displaying text. Fortunately, labels can interpret HTML, so you can leverage CSS to establish maximum width settings. The following code demonstrates how to do this:

JOptionPane.showMessageDialog(
    this, 
    "<html><body><p>

Copy after login

By setting "width" in the CSS, you can limit the message length to your desired width, ensuring that it wraps appropriately.
