Examples of java.util.NavigableMap.lowerEntry()

java.util.NavigableMap.lowerEntry()
Returns a key-value mapping associated with the greatest key strictly less than the given key, or {@code null} if there isno such key. @param key the key @return an entry with the greatest key less than {@code key}, or {@code null} if there is no such key @throws ClassCastException if the specified key cannot be comparedwith the keys currently in the map @throws NullPointerException if the specified key is nulland this map does not permit null keys
