Create iterator for IntBag

Method Detail

getCurrentIndex

public int getCurrentIndex()

return current index This method can be called only per call to next(). This method can not be called after call remove().

Throws:

IllegalStateException - - if the next() method has not yet been called

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.)

Returns:

true if the iteration has more elements

next

public int next()

Returns the next element in the iteration.

Returns:

the next element in the iteration

Throws:

NoSuchElementException - - if the iteration has no more elements

remove

public void remove()

Removes from the underlying collection the last element returned by this 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.

Throws:

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
