Question

I am a beginner and am stuck. I have a Map which is of type String, Object. Once I have declared it:

Map<String, Fish> fishes = new HashMap<String, Fish>();

what do I do now. How do I get my values into the fish object – I am stuck about how to reference the fish object. I know I should use ‘get’, but everything I try doesn’t work.

Apologies, I know this is simpleton stuff, but help would be really appreciated.

Answer 1

Map<String, Fish> fishes = new HashMap<String, Fish>();

To get all your fishes…

for (String key : fishes.keySet()) {
    Fish fish = fishes.get(key);
}
