| K | floorKey(K key) Returns the greatest key less than or equal to the given key, or null if there is no such key. |
| void | forEach(BiConsumer action) Performs the given action for each entry in this map until all entries have been processed or the action throws an exception. |
| V | get(Object key) Returns the value to which the specified key is mapped, or null if this map contains no mapping for the key. |
| SortedMap | headMap(K toKey) Equivalent to headMap(toKey, false) . |
| NavigableMap | headMap(K toKey, boolean inclusive) Returns a view of the portion of this map whose keys are less than (or equal to, if inclusive is true) toKey . |
