using java, finish the two arrayList methods below: public int indexOf(Object o) { } public E remove(int index) { } and then create a class to test the ArrayList methods
For this exercise, you need to shift all the elements in the array one space to the right (increase the index of the element by 1). The last element will wrap around and become the new first element. For example, given: moveUp({"first", "second", "third", "fourth"}); You would return: {"fourth", "first", "second", "third"} in java
Write a method that returns an array list of Characterfrom a string using the following header:public static ArrayList<Character> toCharacterArray(String s)For example, toCharacterArray("abc") returns an array list that containscharacters 'a', 'b', and 'c'.
this is the template to be user. Add the code here according to the question in image. in java language. public class MergeSort { ArrayList getInput(ArrayList<Integer> al) { // } void getOutput(ArrayList<Integer> al) { // } void merge(ArrayList<Integer> al, int beg, int mid, int end) { // } void sort(ArrayList<Integer> al, int beg, int end) { // } public static void main(String[] args) { // TODO Auto-generated method stub } }
You are given an int variable k, an int array zipcodeList that has been declared and initialized, an int variable nZips that contains the number of elements in zipcodeList, and a bool variable duplicates. Write some code that assigns true to duplicates if there are two adjacent elements in the array that have the same value, and that assigns false to duplicates otherwise. Use only k, zipcodeList, nZips, and duplicates. duplicates = false; for (k=0; !duplicates && k<nZips-1; k++)if (zipcodeList[k] == zipcodeList[k+1]) duplicates = true;
Write a java program that uses an ArrayList object to store the following set of names in memory: [Steve, Tim, Lucy, Pat, Angela, Tom] Now write some more code so that the same ArrayList object is augmented with the name 'Steve' after the name 'Lucy' After the ArrayList object has been augmented with the new name, display the original and new lists on the console (as shown below), to verify that the new name is positioned correctly in the list.
Support you have an ArrayList containing random integers. These integers can be any number, and each integer can appear more than once. For example, [2, 19, 21, 19, 21, 1, 3, 3, 6, 21, .....] Your job is to write a method called findEvenFrequentNumbers(ArrayList<Integer> list) that returns an ArrayList which has all the numbers appears in even frequency and in increasing order. e.g. list = [2, 19, 21, 19, 21, 1, 3, 3, 6, 21], should return [3, 19] list = [3, 3, 3, 1, 2, 2, 2, 2, 2], should return [] list = [1, 1, 1, 1, 1], should return [1] Note that you need to provide a class with the main function and also the imports.
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)); } }
Write a Java method named average. The method should take an ArrayList of Integers as a parameter, compute the average of the elements in the ArrayList and return the average to the calling method.
JAVA, PLEASE THE PROGRAM SHOULD USE THE INITIAL ARRAYLIST AND TO EDIT IT NOT TO CREATE A NEW ONE Create a class called OurArrayList and implement the following methods. Do NOT createany auxiliary memory.Include a main method and test all your methods with appropriate examples.a. Write a method called scaleByK() that takes an ArrayList of integers as aparameter and replaces every integer of value K with K copies of itself. Forexample, if the list stores the values (4, 1 , 2, 0 ,3) before the method is called, itshould store the values (4, 4, 4, 4, 1, 2, 2, 3, 3, 3) after the method finishesexecuting. Zeroes and negative numbers should be removed from the list by thismethod
What is printed as a result of executing the following code segment? List list1 = new ArrayList(); list1.add(new Integer(1)); list1.add(new Integer(2)); list1.add(new Integer(3)); list1.set(2, new Integer(4)); list1.add(2, new Integer(5)); list1.add(new Integer(6)); System.out.println(list1); [1, 5, 2, 4, 6] [1, 2, 4, 5, 6] [1, 2, 3, 4, 5] [1, 2, 5, 4, 6]
