Wie kann ich Folgendes sortieren?

System.out.println("Title: " + titleArray[x].getBook());

Diese Zeile bezieht ihre Daten aus einem vom Benutzer eingegebenen Titel. Wenn ich es versuche

System.out.println("Title: " + Arrays.sort(titleArray[x].getBook()));

Ich erhalte folgende Fehlermeldung:

  LibraryBookSort.java:66: error: no suitable method found for sort(String)
          System.out.println("Title: " + Arrays.sort(titleArray[x].getBook()));

Ich nehme an, das liegt daran, dass der Konstruktor bei der Rückkehr keine Sortierung zulässt. Java.util.Arrays; wird ebenfalls importiert.

BEARBEITEN: Nach dem Versuch, String zu sortierenTitles [] = titleArray [x] .getBook (); außerhalb des Sysout, um eine neue Zeichenfolge [] einzurichten, wurde die folgende Fehlermeldung angezeigt ...

  LibraryBookSort.java:63: error: incompatible types
        String sortedTitles[] = titleArray[x].getBook();
                                                     ^

Wie kann ich das zurückgegebene Array sortieren?
