- What is the difference between ArrayLists and arrays?Question: What is the length of the array in MyArrayList after executing the following statements? MyArrayList<Double> list = new MyArrayList<>(); list.add(25.4); list.trimToSize(); list.add(15.4); list.add(35.4); list.add(17.4); list.add(7.4); public class MyArrayList<E> implements MyList<E> { public static final int INITIAL_CAPACITY = 16; private E[] data = (E[])new Object[INITIAL_CAPACITY]; private int size = 0; // Number of elements in the list /** Create an empty list */ public MyArrayList() { } /** Create a list from an array of objects */ public MyArrayList(E[] objects) { for (int i = 0; i < objects.length; i++) add(objects[i]); // Warning: don’t use super(objects)! } @Override /** Add a new element at the specified index */ public void add(int index, E e) { ensureCapacity(); // Move the elements to the right after the specified index for (int…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>
- What is the ArrayList list's starting size?For the following code, indicate the weighted edge values. List<WeightedEdge> list = new ArrayList<>();list.add(new WeightedEdge(1, 2, 3.5));list.add(new WeightedEdge(2, 3, 4.5));WeightedEdge e = java.util.Collections.max(list);e.u = e.v = e.weight =Using Java: Write the following method that returns the maximum value in an ArrayList of integers. The method returns null if the list is null or the list size is 0. public static Integer max(ArrayList list) Write a test program that prompts the user to enter a sequence of numbers ending with 0, and invokes this method to return the largest number in the input.
