更改OptionPane对话框的图标

Question

Ok, enough playing guys, today I'm gonna challenge you big:

So I have an option dialog and want to change the icon of the dialog on the right side so instead of showing a default red cross it will show me a question icon. Is there a basic library in Java that might return me an Icon object for the JOptionPane constructor?

Thanks!!

JOptionPane option=new JOptionPane();
option.showOptionDialog(mainFrame, "Choose shape type", null, 0, 0, null, new String [] {"Lines only","Bounded shapes"}, null);

Why you don't use something like this: there is icon option JOptionPane.QUESTION_MESSAGE

JOptionPane option=new JOptionPane();
option.showOptionDialog(mainFrame, "Choose shape type", null, 0, JOptionPane.QUESTION_MESSAGE, null, new String [] {"Lines only","Bounded shapes"}, null);
