Can I store 1 million records in a hash table for a web based application? How the performence will be effected?

why not try it with a noddy program to see? You could put String representations of integer numbers into a hashtable indexed by the same integer number as an Integer object. Should be easy enough to knock up with a for loop (but make sure you have a LOT of memory first). Wouldn't a persistent data store be a better option in the long run?
