Write the following method that shuffles the elements inan ArrayList of integers:public static void shuffle(ArrayList<Integer> list)

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));   }  }

4. What is the running time of the following code? Points] public static List makeList ( int N) ArrayList 1st = new ArrayList (); for ( inti =0; i < N; i++) { 1st.add (i); lst.trimToSize (); } }

java In this assignment you will swap a position in an array list with another. swap() gets 3 arguments, an Arraylist, a position, and another position to swap with. Example   swap(["one","two","three"],0,2)   returns:["three","two","one"]   public static ArrayList<String> swap(ArrayList<String> list,int pos1,int pos2)    public static void main(String[] args) {    Scanner in = new Scanner(System.in);    int size = in.nextInt();    int pos1 = in.nextInt();    int pos2 = in.nextInt();    ArrayList<String> list = new ArrayList<>();    for(int i=0; i < size; i++) {      list.add(in.next());    }     System.out.println(swap(list, pos1, pos2));   }  }

public static void reverse(ArrayList<Integer> alist){}public static ArrayList<Integer> reverseList(ArrayList<Integer> alist){}   How to use these two headers method and a main method to create the output of  [1,2,3] [3,2,1]

Write the method printTail() method that accepts an array of integers and an integer index as parameters and prints all the array elements starting from the index passed. For example if printTail(x,5) is invoked, it should print all the elements of the array x starting at x[5].

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.

What type of sort is represented by the following code? public void sort(int arrayToSort[]) { int n = arrayToSort.length; for (int num =n/2; num > 0; num /= 2) { for (int i = num;i= num && arrayToSort[j - num] > key) { arrayToSort[j] = arrayToSort[j - num]; j-= num; arrayToSort[j] = key; radix bubble shell selection insertion quick
