¿Cómo puedo ordenar lo siguiente?

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

Esta línea obtiene sus datos de un Título ingresado por el usuario. Si lo intento

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

Recibo el siguiente error:

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

¿Asumo que esto se debe a que el constructor no permite la clasificación al regresar? Java.util.Arrays; También se importa.

EDITAR: después de intentar String sortedTitles [] = titleArray [x] .getBook (); fuera del Sysout para establecer una nueva cadena [], recibió el siguiente error ...

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