HashMap and HashTable

Question

What is the basic difference between HashMap and HashTable.

In which situations each one of two is best to use

Answer 1

Well, Hashtable is synchronized, whereas
HashMap is not.this makes HashMap better for non-threaded applications, as unsynchronized objects typically perform better than synchronized ones.
and also hashtable does not allow null keys or values. hashMap allows one null key and any number of null values.
