HASH TABLE PERFORMANCE A hash table of size 101 that contain six elements will perform very well. It is very unlikely to have any collisions, so the access functions are immediate, running in constant time O(1). This is direct access, just like an array. But a hash table of size 101 that contains 100 elements is likely to perform very poorly because there will have been many collisions in the process of storing its elements. For example, if the string "Lob" had 60 collisions before a free component was found for it, then each time it is accessed, it will take 60 probes to find it. That kind of performance is close to O(n) not much better than a linked list. The solution to the problem described here is to prevent the hash table from becoming too full. This is done by resizing it whenever it reaches a threshold size. The measure of fullness depends upon two parameters: The size of the hash table is the actual number of elements in the table; the capacity of the table is the number of components that it has. The ratio of these two parameters is called the load factor. In the first example cited in this section, the size was 6 and the capacity was 101, resulting in a load factor of 6/101 = 5.94 percent. In the second example, the size was 100, resulting in a load factor of 100/101 = 99.01 percent. The HashMap class automatically resizes its hash table when the load factor reaches a specific threshold value. This threshold value can be set when the hash table is created, using the constructor

COLLISION RESOLUTION ALGORITHMS The collision resolution algorithm used in the previous examples is called linear probing. When a new item hashes to a table component that is already in use, the algorithm specifies to increment the index until an empty component is found. This may require a wraparound back to the beginning of the hash table. EXAMPLE 8.6 Linear Probing
This program extends the program in Example 8.4. It keeps track of which table components are used and the load factor after each hashing.
