Java Hashtableclass is an implementation of hash table data structure. It is very much similar toHashMapin Java, with most significant difference that Hashtable issynchronizedwhile HashMap is not. In thisHashtable tutorial, we will learn it’s internals,constructors, methods, use-cases and othe...

Example: HashTable<Integer,String> Number = new HashTable<Integer,String>(12,0.5); Hashtable object is created with an initial capacity of 12 and with load factor as 0.5. When the number of elements exceeds the product value (12*0.5 = 6), then the capacity will be doubled. ...
