Challenge: Conversion and Traversal

Complete the conversion of an array and tree traversal challenge.

Convert an array to a set

Write a Java program to convert an array into a set and then display it.

The arr is an input parameter for which your code must return the appropriate output on the screen. The returned value must be in ascending order.

For example:

Let’s say you have the array brr as follows:

int brr[] = {2, 2, 2, 2};

After converting brr into the set, the code should return the following:


The output is 2 because the set doesn’t allow duplicates.
