Printing out the content of the List

I am writing code that uses JDBC to access and creates one Book object for each row in the table. The book objects should be stored in a java.util.List implementation. How do I provide a method that returns a reference to that list. How do I print out the content of that list after creating all books  

  public synchronized void excuteQuery() throws SQLException{
     final String QUERY =
         "SELECT TITLE, AUTHOR FROM BOOKS";
     Statement statement = conn.createStatement() ;
     ResultSet results = statement.executeQuery(QUERY);
     while(results.next()){
       JDBCBook book = new JDBCBook(results.getString(1), results.getString(2));
       bookList.add(book);
     }
     results.close();
     statement.close();
