In JAVA Please. Complete the calcAverage() method that has an integer array parameter and returns the average value of the elements in the array as a double. Ex: If the input array is: 1 2 3 4 5 then the returned average will be: 3.0 import java.util.*;public class Numbers {// calcAverage() takes in an int array and returns the average value of elements in the array as a double.public double calcAverage(int[] nums) {/* Type your code here. */ }public static void main(String[] args) {Numbers numObject = new Numbers();int [] nums = {1,2,3,4,5};System.out.println(numObject.calcAverage(nums)); }}
In the box provided, complete the static method filterArray() to return a new array containing the even numbers divisible by 10 in the input array. For example, if the input array arr looks like this: (CLO2) 1 22 11 45 55 25 71 80 8 10 0 1 2 3 4 5 6 7 8 9 Then the method returns this array: 80 10 0 1 i need code in java
Write a method where you’re going to read an array and print second smallest value in that array.You may use the following header for this method:public static void secondSmallest(int[] array)Example:Input array elements: {1, 4, 3, 9, 2, 3, 4}Output:Second Smallest Value:2

Write a static method named createDigits Array (int number) which takes a positive integer as a parameter and creates an array of numbers. For example, the number 123 can be written as 100 + 20+ 3 or (1 x 10^2)+ (2 x 10^1) + (3 x 1). The first number of the array is from the hundreds place, the second number is from the tens place and the last number is from the units place. Therefore, the result is [100, 20, 3] (i.e. the sum of the array is equal to the parameter number). Note: you may assume that the parameter number is always > 100 and less than 999. For example: Test int[] result = createDigitsArray (234); System.out.println(Arrays.toString(result)); int[] result = createDigitsArray(435); System.out.println(Arrays.toString(result)); Result [200, 30, 4] [400, 30, 5]
You are given an array of n integers. Write a java method that splitsthe numbers of the array into two equal groups so that the GCD of all numbers in the second group is equal to one and the GCD of all numbers in the first group is not one. After splitting the numbers display the resulting groups as shown in the sample run below. Note: 1. The array has even size. 2. All elements of the array are less than 100. You are not allowed to define new arrays. 3. 4. You are not allowed to definenew methods or use methods from java libraries. Sample run of the method: Inputarray: (6,7,9,4,3,2} Output Group two: (7,9,3} Group one: (2,4,6} I Ignore Order of numbers. Order is not important //Ignore Order of numbers. Order is not important
Could i get help with this java program where you have to write a static method which reverses an integer array. The array will be a parameter to the method. Put the method in a Test class Your method would be called as follows int [] num = {2, 3, 5, 7, 11, 13, 17}; // Call the method to reverse the array Test.reverse(num); Your method should not print anything. It will be called by the following program: import java.util.Scanner; public class Main { public static void main(String [] args) { // Create a scanner object Scanner in = new Scanner(System.in); System.out.print("How many numbers: "); int len = in.nextInt(); int [] num = new int[len]; System.out.print("Enter " + len + " numbers: "); for(int i = 0; i < num.length; i++) num[i] = in.nextInt(); Test.reverse(num); System.out.print("The numbers reversed are:"); for(int i = 0; i < num.length; i++) System.out.print(" " + num[i]); System.out.println(); } } This program will read in the array and use your method to reverse the…

Define an empty array with 4 elements inside the "main" method. The value '-1' from the user to this arrayRecord the numbers entered by the user in order until they arrive. User array with 4 elementsAfter adding, write the required method so that it can continue adding elements. This method will take the array as a parameter, expand the size of the array and return the array variable.will return. Using this method you defined, the user can add elements to the array.make it continue.
