Hello.  I nedd to write a method to merge two sorted array lists.  I have created the array list and tried to write the method.  I am not sure the method is correct.  Also, I do not know how to call the method in the main method and print the new sorted array.  Can you help?  Thank you. This is what I have so far: import java.util.*; import java.util.ArrayList; public class lab628B { public static void main(String[] args) { ArrayList arr1 = new ArrayList(); arr1.add(1); arr1.add(4); arr1.add(9); arr1.add(16); arr1.add(21); arr1.add(33); arr1.add(41); arr1.add(52); System.out.println("Array 1" + arr1); ArrayList arr2 = new ArrayList(); arr2.add(4); arr2.add(7); arr2.add(9); arr2.add(9); arr2.add(20); arr2.add(25); arr2.add(27); System.out.println("Array 2" + arr2); } public static ArrayList mergeArrays(ArrayList a, ArrayList b) { ArrayList mergeArrays = new ArrayList<>(); merge.addAll(arr1); merge.addAll(arr2); Collections.sort(mergeArrays); return mergeArrays; } }

For JAVA.

Please use the template provided below and make sure the output matches exactly.   import java.util.Scanner;import java.util.ArrayList; public class PhotoLineups {    // TODO: Write method to create and output all permutations of the list of names.   public static void printAllPermutations(ArrayList<String> permList, ArrayList<String> nameList) {      }    public static void main(String[] args) {      Scanner scnr = new Scanner(System.in);      ArrayList<String> nameList = new ArrayList<String>();      ArrayList<String> permList = new ArrayList<String>();      String name;            // TODO: Read in a list of names; stop when -1 is read. Then call recursive method.   }}

This question is in java The Sorts.java file is the sorting program we looked at . You can use either method listed in the example when coding. You want to add to the grades.java and calculations.java files so you put the list in numerical order. Write methods to find the median and the range. Have a toString method that prints the ordered list, the number of items in the list, the mean, median and range. Ex List: 20 , 30 , 40 , 75 , 93Number of elements: 5Mean: 51.60Median: 40Range: 73     Grades.java is the main file import java.util.Scanner;public class grades { public static void main(String[] args) {     int n;     calculation c = new calculation();     int array[] = new int[20];     System.out.print("Enter number of grades that are to be entered: ");     Scanner scan = new Scanner(System.in);     n = scan.nextInt();     System.out.println("Enter the grades: ");     for(int i=0; i<n; i++)     {         array[i] = scan.nextInt();         if(array[i] < 0)         {…
