Examples of java.util.SortedMap.tailMap()

java.util.SortedMap.tailMap()
Returns a view of the portion of this map whose keys are greater than or equal to fromKey. The returned map is backed by this map, so changes in the returned map are reflected in this map, and vice-versa. The returned map supports all optional map operations that this map supports.
The returned map will throw an IllegalArgumentException on an attempt to insert a key outside its range. @param fromKey low endpoint (inclusive) of the keys in the returned map @return a view of the portion of this map whose keys are greaterthan or equal to fromKey @throws ClassCastException if fromKey is not compatiblewith this map's comparator (or, if the map has no comparator, if fromKey does not implement {@link Comparable}). Implementations may, but are not required to, throw this exception if fromKey cannot be compared to keys currently in the map. @throws NullPointerException if fromKey is null andthis map does not permit null keys @throws IllegalArgumentException if this map itself has arestricted range, and fromKey lies outside the bounds of the range
