ArrayList list = new ArrayList(); What is the initial quantity of the ArrayList list? a. 5 b. 10 c. 0 d. 100
Are they equivalent? 1) ArrayList list = new ArrayList(); 2) ArrayList<Object> list = new ArrayList<>();
Examine the following code: ArrayList<String> list = new ArrayList<String>(10) ; list.add("A"); list.add("B"); list.add("C"); list.add(0, "E" ); What element will be at index 2 of the list? What list will be printed after executing the method list.remove(2);
public static int[] goodResize(int[] list, int newSize) { assert list != null && newSize >= 0 : "failed precondition"; int[] result = new int[newSize]; int limit = Math.min(list.length, newSize); for(int i = 0; i < limit; i++) { result[i] = list[i]; } return result; } **Note: Software testing & quality assurance Question: Create a control flow graph based on the coding above and find all these paths: Statement coverage Branch coverage Predicate coverage

The ArrayList is created using the following syntax: String[] array = {"red", "green", "blue"}; ArrayList list Display all the elements of this list using: a) foreach loop b) foreach method with lambda := new ArrayList(java.util.Arrays.asList(array));
KWLinkedList<Integer> list = new KWLinkedList<Integer> (); for(int i = 1; i <= 4; i++) list.add( i ); ListIterator <Integer> iter = list.listIterator(); while(iter.hasNext()) { int x = iter.next(); int y = iter.next(); iter.set(x + y); } while(iter.hasPrevious()) System.out.print(iter.previous() + " ");
What is the ArrayList list's starting size?
Assume that the following method is added to the class KWLinkedList. What is the functionality of the following method? public E function() Node temp = tail; tail.prev.next = null; tail = temp.prev; size-: return temp.data; A Return the element at the tail of the list but do not remove it. B Return the element at the tail of the list and remove it from the list. C Return the second last element of the list and remove it from the list. D Return the second last element of the list but do not remove it.
Assume the following method is in class TestSLList (a method outside the SingleLinked List class). public static void test5Question(SingleLinkedList<Integer> list, int item) { while( list.contains(item) ) list.remove((Integer) item); } The method removes the element at location item from “list”. The method removes the first occurrence of item from “list”. The method removes all occurrences of item from “list”. The method removes the last occurrence of item from “list”.
Assume that the following method is added to the class KWLinkedList. What is the functionality of the following method? public E function() { tail.prev.next = null; Node temp = tail; tail = temp.prev; size--; return temp.data; } O A. Return the element at the tail of the list and remove it from the list. B. Return the element at the tail of the list but do not remove it. O C. Return the second last element of the list and remove it from the list. O D. Return the second last element of the list but do not remove it.
Assume the following method is in class TestArrayList (outside the KWArrayList class). What does it do? public static KWArrayList test6Question(KWArrayList list, String item ) { if (list.isEmpty()) return; KWArrayList list1 = new KWArrayList(); for (int i = 0; i 0) list1.add(list.get(i)); } return list1; } O a. The method checks the elements up the half of the "list"; elements that are greater than item, will be added in reverse order in "list1". The method returns "list1". O b. The method checks the elements up the half of "this" list; elements that are greater than item, will be added to the first half of the "list", otherwise, it will add it to the end of "listl“. The method returns "listl". O. The method checks the elements up the half of "this" list; elements that are greater than item, will be added to the end of "listl". The method returns "list1". Od. The method checks the elements up to the half of the "list"; elements that are greater than item, will be added to the end of…
