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 swap(ArrayList 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 list = new ArrayList<>();     for(int i=0; i < size; i++) {       list.add(in.next());     }     System.out.println(swap(list, pos1, pos2));   }  }

In Java list all the values of the array after the function is called A. static void Fun(int[][]list){ int temp=list[1][2]; list[1][2]=list[0][2]; list[0][2]=temp; } public static void main(String[] args) {   int [][]arr={{10,20,30},{100,200,300}}; Fun(arr); } 10,20,30,300 B. static void Fun(int[]list) { list[3]=5;} public static void main(String[] args) { int []arr={5,6,7,9}; Fun(arr); } C. static void Fun(int[][]list){ list[1][0]=0;} public static void main(String[] args) { int [][]arr={{-2,-3,-4},{5,6,7,9}}; Fun(arr); }

java Create a static method that: is called repeatAll returns ArrayList of Booleans takes in a single parameter - an ArrayList of Booleans This method should modify its ArrayList parameter by repeating its ArrayList values. For example, if the parameter is   (true, false, false) The modified ArrayList should be   (true, false, false, true, false, false)    public static void main(String[] args) {    Scanner in = new Scanner(System.in);    int size = in.nextInt();    ArrayList<Boolean> list = new ArrayList<>();    for(int i=0; i < size; i++) {      list.add(in.nextBoolean());    }     System.out.println(repeatAll(list));   }  }

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));

This is using Data Structures in Java

Are they equivalent? 1) ArrayList<?> list = new ArrayList(); 2) ArrayList<? extends Object> list = new ArrayList<>();

Given an ArrayList called myAL that contains the following: ["blue", "red", "yellow"] write code to insert the elements "purple" and "orange" that keeps the list in alphabetical order.

Given the following class declaration: class List { public: List(); List(const List&); List& operator=(const List&); -List(); // Inserts element in the specified position, returns true if // it was able to insert. // Example, if the list is [4, 2, 1], and the user // calls list.Insert(6, 1) the list would become [4, 6, 2, 1] bool Insert(double element, size_t position) ; // Returns the position of element if found, if not found returns -1 int Index0f(double element)const ; // Removes the element in the given position double Remove(size_t position) ; // Gets the number in the given position double Get(size_t position)const ; // Returns a string representation of the list, elements // separated by commas and the list between brackets string ToString()const ; // Returns the number of elements in the list size_t Size)const; // Returns true if the list is empty, false otherwise bool IsEmpty)const; // Clears the whole list void Clear(); private: struct Node{ double number; Node* next; };…

To declare an array of String called myStrings, we would code: ArrayList<Blank 1> myStrings = Blank 2 ArrayList<String>();
