Subject: Java Programming Question 2Our textbook describes how to implement an array list using a dynamic array. The following code segment adds an element to an array list that is implemented using a dynamic array.But, the code segment has an error in the code. Which line has an errors? Choose one.1 public void add(int i, E e) throws IndexOutOfBoundsException {2 if (i < 0 || i >= n)throw new IndexOutOfBoundsException("lllegal index: " + i);4 if (n == data.length)resize(2 * data.length); // double the capacity of arrayfor (int j=n-1; j >= i; j--)7datalj+1] = data);8 data[i] = e;n++;10 }In the above code:data [] is the array• i is the index of the location in the array where new element is added• e is the element to be added• n is the number of elements currently in the list• The resize method in line 5 doubles the size of the array dataO a.

Project Description: In this project you implement an ArrayStack ADT and use the stack for implementing the following methods: a) Reverse an array of Words: Accept an array of words as input parameter and return an array of words in reverse order. Use the method signature: public static String[] reverseWords (String[] wordList) Example Input: Bird Cat Dog Elephant Output: Elephant Dog Cat Bird

Subject-Object oriented programing Write a program which:• creates a new Array List• adds 5 decimal numbers to it• prints the list to the screenb) In the same program, insert an element in the above ArrayList at index 2. The resulting Array Listmust be one element larger. Print the resulting list to the screen.c) In the same program, replace the element in the ArrayList at index 2 by null. Print the resulting list tothe screen.d) In the same program, remove the element at the last index of the Array List. Print the resulting list tothe screen.e) In the same program, use a 'for' loop to print each element of the Array List to the screen.f) Create a class named ArrayListManager. Into this class, code a method which prints to the screenevery element of an Array List of strings placed at an odd index. Hint: use a modulus.

Java Programming : A party has been organised on cruise. The party is organised for a limited time (T). The number of guests entering (E[i]) and leaving (L[i]) the party at every hour is represented as elements of the array. The task is to find the maximum number of guests present on the cruise at any given instance within T hours. Example 1: Input : 5 > Value of T [7,0,5,1,3] -> E[], Element of E[0] to E[N-1], where input each element is separated by new line [1,2,1,3,4] -> L[], Element of L[0] to L[N-1], while input each element is separate by new line. Output : 8 -> Maximum number of guests on cruise at an instance. Explanation: 1st hour: Entry 7 Exit: 1 No. of guests on ship : 6 2nd hour : Entry Exit : 2 No. of guests on ship: 6-2=4 Hour 3: Entry: 5 Exit: 1 No. of guests on ship : 4+5-1-8 Hour 4: Entry 1 Exit 3 No. of guests on ship: 8+1-3=6 Hour 5: Entry 3 Exit: 4 No. of guests on ship: 6+3-4-5 Hence, the maximum number of guests within 5 hours is 8.

getListRowIndices Method public static java.util.ArrayList<java.lang.Integer> getListRowIndices(int[][] array, int rowLength) This method returns an ArrayList with the indices of rows of the two-dimensional having a length that corresponds to rowLength. You may only use one auxiliary method. The method should create an ArrayList that is passed to the auxiliary in order to place the indices (if any). If no indices are found, an empty (size of 0) ArrayList will be returned. You can assume the array parameter will not be null and every row of the two-dimensional array has an array with a size of at least 0. Your implementation must be recursive and you may not use any loop construct. Do not use ++ or -- in any recursive call argument. It may lead to an infinite recursion. For example, use index + 1, instead of index++. Parameters: array - rowLength - Returns: ArrayList<Integer>

#Steps: Create a Main class. Declare an ArrayList in the main() method and store the given values in it. Create an array called output of the size of the ArrayList. Iterate through for-loop to get each element from the array List and load it into the array using the get() method of the list. Print the array to see the loaded elements. import java.util.ArrayList; import java.util.List; public class Main { public static void main(String[] args) { List<String> nameList = new ArrayList<String>(); nameList.add("Robert"); nameList.add("Samson"); nameList.add("Alex"); nameList.add("William"); System.out.println("Elements of List: " + nameList); // Create an array of the same size as nameList Hint: use size() method // Fetch the elements from the nameList and insert into newly created array // Hint: Use get() method to fetch the elements from…
Searching and sorting in Java programming: Write a method remove, that takes three parameters: an array of integers, the length of the array, and an integer, say removeItem. The method should find and delete the first occurrence of removeItem in the array. If the value does not exist or the array is empty, output an appropriate message. Note: after deleting the element, the array size is reduced by 1. You may assume that the array is unsorted. Thank you. I took Java in 2012 and 2013, and we didn't go too deep in this cocept..just a little bit in the Arrays chapter. i wanted to try something ne! Thank you!
