Write a java program that calls a method called removeZeroes that takes as a parameter an ArrayList of integers and eliminates any occurrences of the number 0 from the list. For example, if the list stores the values [0, 4, 5, 0, 6, 0, 1] before the method is called, it should store the values [4, 5, 6, 1] after the method finishes executing. Print the ArrayList before and after the method call.

- in java language Write a program in which you create an object of type ArrayList named BZ and then add 3 elements in this object and then copy the elements of the object in another object QZ and then cancel the elements of the object BZ and then write the necessary print statements to show it?Write a method called compareSum to be considered in a class outside the KWArrayList class. This method has a parameter list of class type KWArrayList . The method finds the summation of even elements for the first half of list and the summation of odd elements for the second half of list, then compares between the two summations and returns the greater sum. Assume the length of List is even. Method heading: public static int compareSum( KWArrayList<Integer> list) Before run: list= 10 5 50 3 14 33 20 5 (note: the numbers in bold represent the first half) After run: list= 3 5 50 14 33 20 5 Sum1 (for the first half) = 60 Sum2 (for the second half) = 38 Returned value is 60Nedd help in this. Must be in java. make the code unique and no plagerism. write a program that prints out the lists in main after the following methods are called. removeOddLength: Takes an ArrayList of strings as a parameter and removes all of the strings that have an odd length (number of characters), from the list. Return the ArrayList to main and print. swapPairs: Takes an ArrayList and switches the order of values of strings in a pairwise fashion. Your method should switch the order of the first two values, then the next two, then the next two and so on. If the number of values in the list is odd, the method should not move the final element. For example, if the list stores [“madam”, “I”, “am”, “your”, “adam”] your method should change this lists content to [“I”, “madam”, “your”, “am”, “adam”] Return the ArrayList to main and print. intersect: Accepts two sorted ArrayList of integers as parameters and returns one containing only the elements that are found in both. For…
- Write a Java program using ArrayLists that repeatedly asks user to enternumbers. Your program should print the entered numbers and average of thesenumbers. If the user enters ”u”, your program should delete the last enterednumber from the ArrayList. If the user enteres ”r”, the program should removeall elements from the list. If the user enters ”q”, the program should terminate. Hint: You can convert Strings like ”1” to integers with the following code:String str = "1";int one = Integer.parseInt(str);Given main() in the ShoppingList class, define an insertAtEnd() method in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list. The output is: Kale Lettuce Carrots Peanuts public class ItemNode { private String item; private ItemNode nextNodeRef; // Reference to the next node public ItemNode() { item = ""; nextNodeRef = null; } // Constructor public ItemNode(String itemInit) { this.item = itemInit; this.nextNodeRef = null; } // Constructor public ItemNode(String itemInit, ItemNode nextLoc) {…import java.util.ArrayList;import java.util.Arrays;public class PS{/*** Write the method named mesh.** Start with two ArrayLists of String, A and B, each with* its elements in alphabetical order and without any duplicates.* Return a new list containing the first N elements from the two* lists.

- Your activity: write a same java program that will accept 20 integer in a list and returns the index of the first occurrence of the smallest element in the array. Also, write a program to test your method.

The method returns true, if stack st1 and st2 contains the same value in position pos. Otherwise, the method returns false. Assume that both stacks st1 and st2 contain same number of elements. Assume that the position of the top element is 0 and increases by 1 for each subsequent element. The elements of both stacks st1 and st2 must remain in the original relative positions in the stacks at the end of the method. Use common stack operations only such as push, pop, peek, isEmpty, constructor and copy constructor. You can create temporary objects of type ArrayStack in your method. Example: top st1: 4 5 3 10 8 st1: 5 9 4 10 1 If the pos is 3, then both stacks contain 10 in position 3. The method returns true. If the pos is 1, then st1 contains 5 and st2 contains 9 in…Given two ArrayLists: list1=[10,20,30], and list2=[40,50], what is the content of the list1 after executing the following statement: list1.addAll(list2) a.
