Class Prime32List

java.lang.Object

edu.rit.hyb.prime.Prime32List

public class Prime32List
extends java.lang.Object

Class Prime32List encapsulates a list of 32-bit prime numbers. The list of prime numbers is obtained by reading a sequence of values from a file. Each value is an unsigned byte. Each value is the difference between two consecutive odd primes, divided by 2. The file must be created by the Prime32File program.

Class Prime32List provides a method for creating an iterator. The numbers returned by the iterator are the odd primes in ascending order: 3, 5, 7, 11, and so on. The numbers are returned as type long. Once the iterator has read all numbers from the prime file, the iterator returns 0 to signal that there are no more numbers.
