Utilities class can be used with formatted content e.g. html

public static final int getWordStart(JTextComponent c, int offs) throws BadLocationException 
public static final int getWordEnd(JTextComponent c, int offs) throws BadLocationException

To get the last line in your JEditorPane, split the text in the editor on \n as shown below:

String text = editor.getText();
String[] lines = text.split("\n");
String lastLine = lines[lines.length-1];
System.out.println("Last line: " + lastLine);

Similarly, to get the last word, split the last line on space.
