How to sort the ArraList Dates of model

I have read on the ArrayList sort using a comparator but in all examples, people compareTowhich according to some research is a method for strings.

I wanted to sort an ArrayList of items customized by one of their properties: a Date object (getStartDay()). Normally I compare them byitem1.getStartDate () .before (item2.getStartDate ()) so I was wondering if I could write something like:

public class customComparator {
    public boolean compare(Object object1, Object object2) {
        return object1.getStartDate().before(object2.getStartDate());
    }
}

public class randomName {

    Collections.sort(Database.arrayList, new customComparator);

}

    If you do not ingest the files through their structure to map intact complete with media browser and makes your entire organization in another application, Yes, I can see why some of the metadata is missing.

    I also get a DEVICE NOT DETECTED in PP when the camera is clearly working in the new IMAC.

    The remote control is not available for file based devices, so I don't think you need to worry about this.

  • How you sort the list of the next iOS 10?

    I can't know how to sort the list by following in-app music on my iPhone 6 s.  In iOS 9, he had a handle on the right side next to the title of the song that you can tap and drag up/down to change the order of the playlist.  The handle does not appear in the App on iOS 10 music.

    So I guess you can't have activated repeat function.  Once it is off, the handles appear and you can sort your list of songs until the next.

  • How to sort the data in the chart

    Hi, the data feeds that I show on my chart are a kind of account for each of their life cycle. For example, we have 20 in lifecycle = Production, 15 to life = pre direct cycle, 15 = testing life cycle, so on. I want to be able to sort the data by the nature of the life cycel, so in this case, the test-> advance live-> production rather than alphabetically. How to do this?

    Put a 2nd column in your report by using the field of life cycle and then write a CASE statement WHEN:

    CASE {cycle} during the 'Test' THEN 1
    WHEN 'pre Live' THEN 2
    and so on...
    ELSE 0 END

    Hide this column and use it as the sort order.

    see you soon
