Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`Object`	`getKey()`	Gets the current key, which is the key returned by the last call to `next()`.
`Object`	`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.
`Object`	`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.
`Object`	`setValue(Object value)`	Sets the value associated with the current key (optional operation).
`String`	`toString()`
