What collection should I use?

Hi,

I am trying to create a simple search engine and have got a crawler working that stores information of pages into a database. After the user inputs their search times I pull information out of the database and rank it with a certain algorithm. My question is this, I need to record certain information about ranking so I can produce the results ordered by their score. What woud be the best way to do this? I need title, description page and score to be stored for each page and for this information to be presented to me in order of score (highest to lowest).

Thanks in advance.

Make a class X that can store this information
Make sure it implements the Comparable interface
( i.e. implement compareTo() )
Your compareTo() function must compare the scores of the X objects

Than you can store your X objects in a List, sort it (using you compareTo() function), and than output the sorted List.

= simply perform:
Collections.sort(yourList_of_X_objects);

You can use a TreeSet : all elements are always sorted.

Hi,

I think you could use LinkedList collection classes, and HashMaps along with it for faster data accesses.
