Examples of java.util.NavigableMap.ceilingKey()

java.util.NavigableMap.ceilingKey()
Returns the least key greater than or equal to the given key, or {@code null} if there is no such key. @param key the key @return the least key greater than or equal to {@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
