What is the purpose of the SIZE constant in SimpleHashMap?

To limit the number of entries
To define the hash table size
To set the maximum array size
To specify hash function

The correct answer is: To define the hash table size

The purpose of the SIZE constant in SimpleHashMap is to define the size of the hash table, which is the underlying data structure used to store key-value pairs. This size determines the number of buckets in the hash table and is used to distribute and retrieve the key-value pairs more efficiently. Option A is incorrect because the size constant does not limit the number of entries, it only defines the size of the hash table. Option C is incorrect because the size constant defines the size of the hash table, not the maximum array size. Option D is incorrect because the size constant is not used to specify the hash function, which is responsible for mapping keys to specific buckets in the hash table.
