    Modifier and Type
    Method
    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.
    boolean
    hasPrevious()
    Checks to see if there is a previous entry that can be iterated to.
    K
    next()
    Gets the next key from the Map.
    K
    previous()
    Gets the previous 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.
