I've created a linkedlist<FileInfo> - file info is class which contains following:

class FileInfo {
      public String Name; 
      public Long Length; 
      public Long LastModified;
      public String LockedBy;
}

I need to order this list based on name or lastmodified. How can I achieve this? I can't use

Collections.sort(actTreeFileInfoLinkdList)

because generic is not a string. How can I sort it? I'm new in java, so maybe there is obvious and simple answer I cant figure out, thanks :)

Pass a `Comparator` to Collections.sort – Eran Nov 29 '17 at 12:47
so like this? Collections.sort(Comparator) – h0neybaLL Nov 29 '17 at 12:49
No, `Collections.sort(actTreeFileInfoLinkdList,comparator)` where comparator is a `Comparator` – Eran Nov 29 '17 at 12:50
Or implement [`Comparable`](https://docs.oracle.com/javase/8/docs/api/java/lang/Comparable.html) in `FileInfo`. – Elliott Frisch Nov 29 '17 at 12:50
