是否可以在JOptionPane.showMessageDialog（）中更改字符串颜色

Question

So i have this code, which opens a JOptionPane with information about the exception:

String fileName=e.getStackTrace()[0].getFileName();
String methodName=e.getStackTrace()[0].getMethodName();
String line=String.valueOf(e.getStackTrace()[0].getLineNumber());

JOptionPane.showMessageDialog(null, new JLabel("There was an unexpected "+e+" at file: "+fileName+" in method: "+methodName+" in line: "+line));

The only thing i am not happy with is the fact that its all the same color, so i thought why not change the color of the Strings regarding the exception to red. So i googled a bit and found several similar question on SO, and also tried what they suggested there with html-tags and such, but i was not successful. Is there any working way to color the text? Currently it looks like this with html tags

Answer 1

The entire string needs to be enclosed within the HTML tags. For more information, see How to Use HTML in Swing Components.
