Java: Instantiate Google Collection's HashBiMap

bimap, guava, java

Solution

When calling static generic functions, you don't pass the type parameters:

 HashBiMap<Character, Integer> charOcc = HashBiMap.create();

Also really you shouldn't code to the implementation class, so you're better off doing

 Map<Character, Integer> charOcc = HashBiMap.create();

or

 BiMap<Character, Integer> charOcc = HashBiMap.create();

Problem

I'm using Eclipse, and I've added `google-collect.1.0-rc2.jar` as a referenced library. Yet somehow this still doesn't work: ``` import com.google.common.collect.HashBiMap; public class Odp { //... HashBiMap<Character, Integer> charOcc = HashBiMap<Character, Integer>.create(); } ``` Eclipse gives the following errors: Multiple markers at this line - HashBiMap cannot be resolved - Character.Integer cannot be resolved - Syntax error on token ",", "." expected - Syntax error on token ".", delete this token - The method create() is undefined for class Odp What am I doing wrong? Other Google stuff, like Joiner, works fine. (But Joiner is not generic.)
