Method Summary

Methods
Modifier and Type	Method and Description
`K`	`getKey()` Gets the current key, which is the key returned by the last call to `next()`.
`V`	`getValue()` Gets the current value, which is the value associated with the last key returned by `next()`.
`boolean`	`hasNext()` Checks to see if there are more entries still to be iterated.
`K`	`next()` Gets the next key from the `Map`.
`void`	`remove()` Removes the last returned key from the underlying `Map` (optional operation).
`void`	`reset()` Resets the iterator back to the position at which the iterator was created.
`V`	`setValue(V value)` Sets the value associated with the current key (optional operation).
`String`	`toString()`
