(ISRP) A person who wants to return to work at a job that can negatively affect his health asks, "Can I go back to work?" how to respon this? JAVAWrite a Java program that gets a one-dimensional integer array and return the count of unique elements in the array. You will write a method numUnique() that takes in the array and returns the count.For example,Enter the number of elements you want to store:8Enter the elements of the array: 4 2 3 1 2 3 2 1 Original array length: 8Array elements are: 4 2 3 1 2 3 2 1 The number of unique elements is: 4One way to find similar elements would be to use nested loops and/or multiple arrays. But there's a nifty trick we can use: sort the array and then check for adjacent elements. For example, in the example above the original array is:4 2 3 1 2 3 2 1Sorted, this array will be:1 1 2 2 2 3 3 4Now we can compare elements next to each other. Let's start with array[i] where i is 0, our first unique value (i.e., the value 1). If its successor, array[i+1] is the same, then we wouldn't count it since it's not unique. We'd continue this process of comparing adjacent values until we've processed the entire array.Use Arrays (import java.util.Arrays)--that class we used before with its .toString() method. Look up how to use its .sort() method.
