Let's look at the solution of TreeSet exercises.

## We'll cover the following

## Problem 1: Numbers greater than 50

Given an array of numbers, find all the numbers that are greater than 50.

## Solution

There is a `tailSet(E e)`

method in the **TreeSet** class that returns a set of all the elements that are greater than the provided element. We will add all the elements from the array to a **TreeSet**. Then we will find all the elements greater than 50 using the `tailSet()`

method.
