THIS IS DONE IN JAVA Given the following method signature, write code that will shift all values of the arrayto the left by one location, and return the resulting array. The first value should endup in the last location.Ex. If the array passed in is {1, 2, 3, 4} the result would be {2, 3, 4, 1}public int[] shiftValues(int[] nums) {

Introduction of the Program: The Java program takes the size of the array from the user then the user enters the elements of the array after that the program shifts the array elements to the left by one position and then the program displays the shifted array.Source code of the Program: Save the below code as Main.java //Main.java//import package Scannerimport java.util.Scanner; public class Main { //Method to shift the array to left by one position public int[] shiftValues(int[] nums){ int temp=nums[0]; for(int i=0;i<nums.length-1;i++){ nums[i]=nums[i+1]; } nums[nums.length-1]=temp; return nums; } //Driver method public static void main(String args[]){ //declaring the object of the class to access the method Main obj= new Main(); //declaring the scanner class object Scanner scanner = new Scanner(System.in); int size; System.out.println("Enter the size of the array :") ; //taking the size of the Array from the user size = scanner.nextInt(); int[] arr = new int[size]; //taking the elements of the array System.out.println("Enter the elements of the Array") ; for(int i=0;i<size;i++){ arr[i] = scanner.nextInt(); } //displaying the original array System.out.println("Original array"); for(int i=0;i<size;i++){ System.out.print(arr[i]+" "); } //calling the function to shift array elements arr=obj.shiftValues(arr); System.out.println("\nNew array after rotating by one postion in the left direction"); for(int i=0;i<size;i++){ System.out.print(arr[i]+" "); } System.out.println(); } }Run the code and it will display the below output.
