RangeIterator

Language/Type: Java collections Iterator

Author: Marty Stepp (on 2013/01/29)

Suppose we have a class called IntRange representing a range of integers, implemented as follows: 

public class IntRange {
    private int min;
    private int max;   // both ends are inclusive
    ...
    // your iterator class goes here
}

The author of this class wants to make it possible to use integer ranges as the target of a for-each loop: 

IntRange range = new IntRange(7, 15);
for (int n : range) {
    System.out.print(n + " ");   // 7 8 9 10 11 12 13 14 15
}

Write a private class named RangeIterator that would be usable as an inner class to implement an iterator over the integers in an IntRange. Implement the hasNext and next operations; when the remove method is called, you can throw an UnsupportedOperationException. Your iterator should not construct any internal data structures.
