public PairIterator(java.lang.Object one,
                    java.lang.Object two)
```
    Create an iterator over two objects
    
    Parameters:
    
    one - the first object to be returned
    
    two - the second object to be returned
- Method Detail
  - hasNext
```
public boolean hasNext()
```
    Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)
    
    Specified by:
    
    hasNext in interface java.util.Iterator
    
    Returns:
    
    true if the iterator has more elements.
  - next
```
public java.lang.Object next()
```
    Returns the next element in the iteration.
    
    Specified by:
    
    next in interface java.util.Iterator
    
    Returns:
    
    the next element in the iteration.
    
    Throws:
    
    java.util.NoSuchElementException - iteration has no more elements.
  - remove
```
public void remove()
```
    Removes from the underlying collection the last element returned by the iterator (optional operation). This method can be called only once per call to next. The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method.
    
    Specified by:
    
    remove in interface java.util.Iterator
    
    Throws:
    
    java.lang.UnsupportedOperationException - if the remove operation is not supported by this Iterator.
    
    java.lang.IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method.
