Grouping elements of a list into sublists (maybe by using guava)

Question

I want to group elements of a list. I\'m currently doing it this way:

public static  List> group(final List list, fina         


        

Answer 1

The easiest and simplest way would be using: Lamdaj grouping feature

The above example can be re-written:

List badGuys = Arrays.asList("Inky", "Blinky", "Pinky", "Pinky", "Clyde");
Group group = group(badGuys, by(on(String.class).length)));
System.out.println(group.keySet());
