    Default Array to Linked List

    Need help, does anyone know how to:

    How do I Change this to LinkedLists

    private final int maxCrimes = 10;
    private Crime[] crime = new Crime[maxCrimes];
    private int crimeNo = 0;
    private Date start, end;
    private int highestCrimeLevel = 0;

    public Crimes() {
    crime[crimeNo] = new Crime("crime");
    start = crime[crimeNo].start();
    end = crime[crimeNo].end();
    crimeNo++;
    }

    I know how to change the array:
    from: private Crime[] crime = new Crime[maxCrimes];
    to : private LinkedList<Crime> crime = new LinkedList<Crime>();

    and adding elements to the list:
    from: crime[crimeNo] = new Crime("crime");
    to : crime.add(new Crime("crime"));

    but my problem is I don't know how to convert this to list

    start = crime[crimeNo].start();
    end = crime[crimeNo].end();

    I tried:
    start = crime.start();
    end = crime.end();

    Thanks :)

    The Arrays class and the Collections framework can help you out:

    Java Code:
    T[] array= new T[ ... ];
    List<T> list= new LinkedList<T>(Arrays.asList(array));
    kind regards,

    Great, have you read what was posted hours earlier in this thread or do you simply want to dump the url of your blog?

    kind regards,
