Error in HashTable Construction

#1

while writing this

this.BucketArray = (GenericLinkedList[]) new GenericLinkedList[size];

we get error :-

Type safety: Unchecked cast from GenericLinkedList[] to
GenericLinkedList<HashMap<K,V>.HTPair>[]

HOW TO RESOLVE THIS

@RULEREMPIRES,
Can you share the complete code?

see line no:- 16 and 35

@RULEREMPIRES,
Your code is correct.

The problem is the cast isn’t checked. So, you have to check it yourself. You can’t just check a parameterized type with instanceof, because the parameterized type information is unavailable at runtime, having been erased at compile time.

But, you can perform a check on each and every item in the hash, with instanceof, and in doing so, you can construct a new hash that is type-safe. And you won’t provoke any warnings.

Or you can just add @SuppressWarnings("unchecked") on top of the hashmap constructor
