Question

I’m currently working on a holiday project aimed at simulating biological body clocks. The long & short of it is that I’ve decided to use a hash table as a “concentration” object to simulate a cell and its interacting units.

My main question is: is it possible to use the Java standard HashTable in such a way that it has a constant size? i.e. regardless of input (which will be appropriately limited) it doesn’t change.

Thanks in advance!

Answer 1

The constructor HashTable(int) takes the initial capacity as a parameter. The default load factor is 0.75. Then:

No rehash operations will ever occur if the initial capacity is greater than 
the maximum number of entries the Hashtable will contain divided by its 
load factor.
