For example, to populate the StyledDocument for a JTextPane , after creating the
DefaultStyledDocument , you add content to it by calling the public void insertString(int
offset, String contents, AttributeSet attributes) method, which happens to throw a
BadLocationException . You can then change the attribute set and add more attributes. So, if
you wanted to create content that was both bold and italic, you would add two attributes to a
SimpleAttributeSet and insert the content into the document:

SimpleAttributeSet attributes = new SimpleAttributeSet();
attributes.addAttribute(StyleConstants.CharacterConstants.Bold, Boolean.TRUE);
attributes.addAttribute(StyleConstants.CharacterConstants.Italic, Boolean.TRUE);
