Java code  8. Given an existing ArrayList named friendList, find the first index of a friend named Sasha and store it in a new variable named index.

Vectors are synchronized while ArrayLists are not. Group of answer choices True False

The program first reads integer cityCount from input, representing the number of pairs of inputs to be read. Each pair has a string and a character. One City object is created for each pair and added to vector cityList. Write the PrintSelectedCities() function in the SmallTowns class using Print() to output all the City objects with tour status equal to 'N'. Ex: If the input is: 4 Sundance N Adomstown N Hum Y Hanna Y then the output is: City: Sundance, Tour: N City: Adomstown, Tour: N Note: The vector has at least one element. #include <iostream>#include <vector>using namespace std; class City {public:void SetNameAndTour(string newName, char newTour);       char GetTour() const;       void Print() const;private:string name;char tour;}; void City::SetNameAndTour(string newName, char newTour) {name = newName;tour = newTour;} char City::GetTour() const {   return tour;} void City::Print() const {   cout << "City: " << name << ", Tour: " << tour <<…

in java programming answer the following: Given an array called myArr (created as ArrayList<T>) and contains the {1,2,3,4,5,6,7}. (a) what would be the contents of this array after myArr.add(10). b) write the content of myArr after myArr.add(4, 11);

Java code  12. Given an existing ArrayList named contactList, find the number of contacts in the ArrayList and store it in the existing variable named numContacts.

java Create a static method that: is called appendPosSum returns an ArrayList of Integers takes one parameter: an ArrayList of Integers This method should: Create a new ArrayList of Integers Add only the positive Integers to the new ArrayList Sum the positive Integers in the new ArrayList and add the Sum as the last element For example, if the incoming ArrayList contains the Integers (4,-6,3,-8,0,4,3), the ArrayList that gets returned should be (4,3,4,3,14), with 14 being the sum of (4,3,4,3). The original ArrayList should remain unchanged.  public static void main(String[] args) {    Scanner in = new Scanner(System.in);    int size = in.nextInt();    ArrayList<Integer> list = new ArrayList<>();    for(int i=0; i < size; i++) {      list.add(in.nextInt());    }     System.out.println(appendPosSum(list));
