java - Why are Vector and HashTable widely believed to be due for deprecation? -

-

possible duplicate:
why java vector class considered obsolete or deprecated?

also, there official word sun/oracle on that?

thanks.

edit: i'm aware of other topic, didn't mention whether there official word on this, why topic worded "widely believed". plus, topic addresses vector, not hashtable.

vector synchronized; don't need incurs serious overhead. hashtable synchronized , can't reasonably store nulls.

people use various lists , hashmap instead.
