Java
LinkedHashSet hs = new LinkedHashSet();
// add elements to the hash set
hs.add("B");
hs.add("A");
hs.add("D");
hs.add("E");
hs.add("C");
hs.add("F");
System.out.println(hs);
} }
This will produce the following result:
[B, A, D, E, C
The TreeSet Class
TreeSet provides an implementation of the Set interface that uses a tree for storage.
Objects are stored in a sorted and ascending order.
Access and retrieval times are quite fast, which makes TreeSet an excellent choice when
storing large amounts of sorted information that must be found quickly.
Following is the list of the constructors supported by the TreeSet class.
