Question

I'm trying to simulate a directly mapped cache in java. Any ideas on which data structure to use to represent the cache?

Answer 1

Try a Map interface for the reference type and WeakHashMap as the implementation:

int initialCapacity = 1024;    
Map<K, V> cache = new WeakHashMap<K, V>(initialCapacity);

Answer 2

It sounds like you're talking about hardware caching. Would a Map<Long, Byte[]> work?
