Java search in text file with joptionpane? -

-

im new java. im quite lost here, im working on project should search in text file corresponding word, line line. got little someone, there´s errors gui in joptionpane.

this have until now. gui:

private void jmenuitemlookupactionperformed(java.awt.event.actionevent evt) {                                                     joptionpane.showoptiondialog(null, "title", "message",      joptionpane.default_option, joptionpane.plain_message,     null, options.toarray(new string[] {}), options.get(0)); }

and code search. 

public string lookup(string question){     list<string> options = new arraylist<>();     (object value : data.values()) {     if (value.tostring().startswith(question)) {         options.add((string) value);     } }

move list<string> options = new arraylist<>(); outside lookup method , make class variable. compiler cannot find options object.
