Tree Set:

It is one of the two sorted collections.
Uses the “Read-Black” tree structure and guarantees that the elements will be in ascending order.
We can construct a tree set with the constructor by using a comparable (or) comparator.

Example:

public class Fruits{
public static void main (String[ ]args) {
Treeset&lt;String&gt; names= new TreeSet&lt;String&gt;( ) ;
names.add(“cherry”);
names.add(“banana”);
names.add(“apple”);
names.add(“kiwi”);
names.add(“cherry”);
System.out.println(names);
}
}

Output:

[apple, banana, cherry, kiwi]

TreeSet sorts the elements in ascending order. And duplicates are not allowed.
