Map>map = newHashMap();

Nice, right? Thanks to generics and those handy factory methods that the Collections guys have provided us with, we no longer have to write things that Java really should understand, right?

Only thanks to the great Java generics we need libraries like this.

Your comment got lost in the approval list, sorry.

The arrayListOf method is a method we have implemented ourselves, but all it does it wrap the ImmutableList.of and ImmutableMap.of static methods to try and make it even nicer. Therefore you do not find it in the Guava documentation.

arrayListOf does not exist, does it? The guava documentation does not list this function.

Hi Dimitri! Yes, Multimap is very useful! Make sure you check out the other parts of this series, where we cover Multimaps in part 4 here:

I happened to use a useful interface in guava: Multimap.
Thank to Multimap you can define a variable like this:

Multimap multimap = HashMultimap.create();

whenever you need to handle a map with a list as value, i.e.:

Map multimap = new HashMap;

Quite handy if you have to loop some other collection to populate the map and you don’t want to deal with the list of values mapped to same key.

New to Guava – does anyone have a list of good Eclipse favorites to add for Guava development?
