Returns a view of the portion of this set whose elements are less than (or equal to, ifinclusiveis true)toElement. The returned set is backed by this set, so changes in the returned set are reflected in this set, and vice-versa. The returned set supports all optional set operations tha...

The stack interface represents a last-in-first-out (LIFO) collection of objects. The usual push and pop operations are provided, as well as a method to peek at the top item on the stack, a method to check whether the stack is empty and the size (number of elements). All stacks imple...

A TreeSet should be our primary choice if we want to keep our entries sorted as a TreeSet may be accessed and traversed in either ascending or descending order, and the performance of ascending operations and views is likely to be faster than that of descending ones. The Principle of Locali...
This implementation provides guaranteed log(n) time cost for the basic operations (add, remove and contains). Note that the ordering maintained by a set (whether or not an explicit comparator is provided) must be consistent with equals if it is to correctly implement the Set interface. (See ...
The HashSet and TreeSet classes in Java Collections are both implementations of the Set interface with distinct characteristics. HashSet uses a hash table to store unique elements, ensuring constant-time performance for basic operations like add, remove, and contain. It does not maintain any specif...
