什么是 Blackberry API 相当于 Java 的 HashMap 集合？

Question

Is there a collection which is similar to a Java map with a key and value?

Answer 1

Hashtable would be the closest general purpose collection. If you are working with primitive keys or keys and values, there are some variations that do a better job of preserving types, and can be a little more efficient too:

• IntHashtable
• IntIntHashtable
• IntLongHashtable
• LongHashtable
• LongIntHashtable
