Searching Arrays

[BHCluster]

This is what I have so far

ArrayList<AddressBook> book = new ArrayList<AddressBook>();

System.out.println();
System.out.println("Sorted: ");
ListIterator list = book.listIterator();
while(list.hasNext()) {
Collections.sort(book);
System.out.println(list.next());
System.out.println();

And I get an error cannot find symbol in java, so can somebody tell me what am I doing wrong. Thank you for taking interest.

Did you import all your classes?

When you get an error, it's very important that you copy the full text of the error message and paste it with your question.

Is that you get error in sort() method? It should be, see the Java doc for more details.
