Write a method that returns all strings from an array list of a given length, without changing the original array list. Complete the following code. ArrayListUtil.java 1 import java.util.ArrayList; 2 3 public class ArrayListUtil 4 { 5 /** Gets all strings from an array list of a given length. @param words an array list of strings @param wordLength the length of the words to get @return an array list with the words of length wordLength * / public static . . . wordsOfLength(. . . words, { 6 7 8 9 10 11 . wordLength) 12 13 } 15 } 14 Tester.java 1 import java.util.ArrayList; 3 public class Tester 4 { public static void main(String[] args) { ArrayList words = new ArrayList(); words.add("Mary"); words.add("had"); words.add ("a"); words.add ("little"); words.add("lamb"); words.add("its"); words.add("fleece"); words.add("was"); words.add("white"); words.add("as"); words.add("snow"); 5 7 8 9 10 11 12 13 14 15 16 17 18 19 System.out.println(ArrayListUtil.words0fLength(words, 3)); System.out.println("Expected: [had, its, was]"); System.out.println (ArrayListUtil.words0fLength(words, 6)); System.out.println("Expected: [little, fleece]"); System.out.println(ArrayListUtil.words0fLength(words, 7)); System.out.println("Expected: []"); // Check that words hasn't been changed System.out.println(words); System.out.println ("Expected: [Mary, had, a, little, lamb, its, fleece, was," 20 21 22 23 24 25 26 27 28 29 + white, as, snow]"); } 31 } 30

java Create a method that: is called timesTwo returns an ArrayList of Integers takes in a single parameter - an ArrayList of Integers called nums This method should take the ArrayList parameter and multiply every value by two.   public static void main(String[] args) {    Scanner in = new Scanner(System.in);    int size = in.nextInt();    ArrayList<Integer> list = new ArrayList<>();    for(int i=0; i < size; i++) {      list.add(in.nextInt());    }     System.out.println(timesTwo(list));   }  }

Method Details: public static java.lang.String getArrayString​(int[] array, char separator) Return a string where each array entry (except the last one) is followed by the specified separator. An empty string will be return if the array has no elements. Parameters: array - separator - Returns: stringThrows:java.lang.IllegalArgumentException - When a null array parameter is provided

use java to create a card game with the implements listed for the program. If you are able to do the first couple of steps that would be helpful and for step one use an array list with the following code. The code below should create 52 cards. String[] suits = {"Hearts", "Clubs", "Spades", "Diamonds"}; String[] numbers = {"A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"};          for(String oneSuit : suits){    for(String num : numbers){                       System.out.println(oneSuit + " " + num);                     } }

java Create a static method that: is called appendPosSum returns an ArrayList of Integers takes one parameter: an ArrayList of Integers This method should: Create a new ArrayList of Integers Add only the positive Integers to the new ArrayList Sum the positive Integers in the new ArrayList and add the Sum as the last element For example, if the incoming ArrayList contains the Integers (4,-6,3,-8,0,4,3), the ArrayList that gets returned should be (4,3,4,3,14), with 14 being the sum of (4,3,4,3). The original ArrayList should remain unchanged.  public static void main(String[] args) {    Scanner in = new Scanner(System.in);    int size = in.nextInt();    ArrayList<Integer> list = new ArrayList<>();    for(int i=0; i < size; i++) {      list.add(in.nextInt());    }     System.out.println(appendPosSum(list));

public class arrayOutput ( public static void main (String [] args) { final int NUM ELEMENTS = 3; int[] userVals = new int [NUM_ELEMENTS]; int i; } Type the program's output userVals [0] = 2; userVals [1] = 6; userVals [2] = 8; for (i = userVals.length - 1; i >= 0; −−1) { System.out.println(userVals [1]); } C.C. ? ? ??

Need help with menu loop please

Write a Java method (do not write a class, only the method) with the following signature: Return type: void Parameters: 2D integer array Name: printDiagonal Implement the method code that will print out the values of the 2D array along the Diagonal from left to right. For example, if the array had the following values: 56    78    98 21    33    55 98    44    11        The method should print to the console:   56,33,11 The above 2D array example is only given for you to understand the problem Do not hard code the values in your solution or assume the array is the same as the given data. Your method should work for all 2D integer arrays.

Write a static method that displays all combinations of picking two numbers from the array list: public static void combinations(ArrayList<Integer> list) Include the driver program that prompts the user to enter 10 integers and displays all combinations of picking two numbers from the array list.
