Initialize Static Array of Map in Java

Question

Im having problems when trying to initialize the variable:

Map<Sentence, Float>[] vectorValueSentences; // this is ok

/* but this is not */ vectorValueSentences = new HashMap<Sentence, Float>()[100];

I search on what to do but i didnt find any. I read that the object to be initialize has to be static but i dont find a way to declare the Map static.

Thank you for your help!

Can you include a fuller snippet? It's hard to understand without some more context. — Mureinik

If vectorValuesSentences is not declared before calling the line vectorValueSentences = new HashMap<Sentence, Float>()[100];, obviously its wrong — sam

Because of how generics in Java work, you cannot directly create an array of a generic type (such as Map<Object, Object>[]). Or You are trying to do something else? More in: stackoverflow.com/questions/14917375/… — Mazeryt

You should consider using a List of Maps. List<Map<Sentence, Float>> vectorValueSentences = new ArrayList<Map<Sentence, Float>>(); — Pavan Dittakavi
