    Java Array listing

    hi, im a first year computer scientist and im trying to make a java program to solve the 8-puzzle problem. i think i can make everything work except i'm getting confused about array.

    everytime i expand a state in the puzzle it produces 2,3 or 4 new states these are all in arrays. i need to make a list of these arrays somehow, so that i can add these new arrays to te top of the list or te bottom, and so its possible to sort the list. i've been wading through websites lookign for a solution but everythign is call abit to general as ive only had 7 weeks of java experience, and havent been told exactly wat an object or a class is yet.

    Any help would be appreciated

    If your trying to sort things, try using a TreeSet or other SortedSet interface. You should be able to add stuff like this:
    TreeSet<State> set = new TreeSet<State>();
    State[] states;
    // Code here to get states
    set.add(new State());
    Hope this helps.
