Method Detail

hasNext

public boolean hasNext()

Returns true iff I have more elements. (In other words, returns true iff a subsequent call to next will return an element rather than throwing an exception.)

Returns: true iff I have more elements

public char next()

Returns the next element in me.

Returns: the next element in me

Throws: NoSuchElementException if there is no next element

remove

public void remove()

Removes from my underlying collection the last element returned by me (optional operation).

Throws: UnsupportedOperationException if this operation is not supported IllegalStateException if CharIterator has not yet been called, or CharIterator has already been called since the last call to CharIterator.
