The code is correct assuming List of strings. I have not modified any of your source code just to give you idea that it works fine. List contain new ArrayList() contain.add("HPDH-1,001, Check-out date: 7/7/7") contain.add("JTI-1,001, Check-out date: 7/7/7") String code "JTI-1 " for String valueit.next() System.out.println("List Iterated Value: "value) System.out.println("-- Example for Loop from ArrayList Java HashSet Example Code for add and collect data Java TreeSet Example to sorting data with java Tre Java StringBuffer Example to append a lot of Strin Tags java arraylist for-loop contains.Newbie Java Programmer needs help for loops.

Tags: java for-loop arraylist contains.
Yes, contains() for a List takes time proportional to the size of the list. If you need to be able to check membership faster, consider using, for example, a HashSet, which can check membership in constant time.
