I currently have this piece of code:

Map<Double, Character> memory = new HashMap<Double, Character>();

However it returns this error upon compiling:

GameLogic.java:5: type Map does not take parameters
Map<Double, Character> memory = new HashMap<Double, Character>();
   ^
1 error

I have no idea why its doing this as I see no reason it should after looking at other questions. It is within the 'GameLogic' class. Please could someone help.

    @pokeairguy: it is probably causing ambiguity and preferring your self defined class over the actual one. Try it like this: java.util.Map<Double, Character> memory = new HashMap<>(); Commented Feb 24, 2014 at 1:32

Two possible mistakes:

  • You are using JKD 1.4
  • You imported something else than java.util.Map

You may have imported the wrong Map class. java.util.Map takes parameters.
