Explanation of Solution
Method to add all the elements from one collection to another collection:
Addall(collection C) is the method used to add all the elements from one collection to another. The elements may be added individually.
Sample Program:
//Java program to illustrate addAll(Collection c)
import java.util.ArrayList;
public class Sample
{
public static void main(String args[])
{
// Creating array list1
ArrayList<Integer> collect1 = new ArrayList<Integer>(5);
// Adding elements to the list1
collect1.add(12);
collect1.add(20);
collect1.add(45);
// prints all the elements available in array //list1
System.out.println("Printing list1:");
for (Integer number : collect1)
System...

- Create an ArrayList of strings to store the names of celebrities or athletes. Add five names to the list. Process the list with a for loop and the get() method to display the names, one name per line. Pass the list to a void method. Inside the method, Insert another name at index 2 and remove the name at index 4. Use a foreach loop to display the arraylist again, all names on one line separated by asterisks. After the method call in main, create an iterator for the arraylist and use it to display the list one more time.arrow_forwardThere are two different methods you to add a range to an ArrayList.These methods are AddRange and InsertRange.implement a c# program to demonstrates how these two methods are used:arrow_forwardArrays: create an array of a given type and populate its values. Use of for loop to traverse through an array to do the following : to print the elements one by one, to search the array for a given value. ArrayList: create an ArrayList containing elements of a given type . Use some of the common ArrayList methods to manipulate contents of the ArrayList. Write methods that will take an ArrayList as its parameter/argument ; and/or return an ArrayList reference variable as its return type. Searching for an object in an Array: Loop through the ArrayList to extract each object and to check if this object’s attribute has a given value. Explain how and why interfaces are used in Java Collection Framework. Explain the major differences between a Stack and a Queue. Be able to use stack and queue methods. What is meant by O(N) notation? Express the complexity of a given code using the O(N) notation.arrow_forward
- Do not copy froom outside sources as they have different instructions. In python. please include docstring. The Strawberry Stand methods are:* init method - takes one parameter, the name of the stand; initializes the name to that value, initializes current day to zero, initializes the menu to an empty dictionary, and initializes the sales record to an empty list* a get method for the name: get_name()* add_menu_item - takes as a parameter a MenuItem object and adds it to the menu dictionary. New items can be added to the menu on any day* enter_sales_for_today - takes as a parameter a dictionary where the keys are names of items sold and the corresponding values are how many of the item were sold. If an item in the menu doesn't appear in the dictionary, then there were no sales of that item on that day. If the name of any item sold doesn't match the name of any MenuItem in the dictionary of MenuItem objects, this method should do nothing except raise an **InvalidSalesItemError** (you'll…arrow_forwardHow do you print out all keys currently stored in a map?arrow_forwardcontinue from first question, Client class:The client program will allow entry of these data for several different student into an ArrayList and then perform some analysis and queries.Your client class (program) will provide the user with a menu to perform the following operations. You will also need to load the information of the students from a CSV file (student.csv) before displaying the menu. You only need one ArrayList and one menu for this. For the csv file, your first item can be U or G to differentiate whether the entry is creating a UndergraduateStudent object, or a GraduateStudent object. You can then decide how you want other data to be listed in the csv file. You should specify clearly in your documentation the data format of the CSV files used in this assignment.1. Quit (exit the program)2. Add (to the ArrayList) all the marks information about an undergraduate or graduate student by reading it from another CSV file. Your program will ask for the file name.3.

- How do you determine the number of elements in a set?arrow_forwardThere aren't any set cells that have the same values.arrow_forwardQ.Create an interesting educational information chat box that asks the user to give an input question and then answers the question given by user with a suitable answer. It should match the question of user with a suitable answer avaliable . You can make use of list for different questions and answers. (if possible) Save two to three answers for a single question and then for random selection of elements from those answers use random choice(list) method from random module that returns a random element. Also for a user question that doesn't matches with the questions present in the chat box it should display statement like "oops i can't answer that" "sorry i am not intelligent enough" "could u please ask something else" using random method so that every time one of these statements appear **coding language python ***try using basic programming techniques in python without using arrays and pointers * * * copy paste the program itself and also the screenshot of program and output…arrow_forward

One method should test for equality. The other methods should support the other possible comparisons. In each case, the method returns the result of the comparison of the two students' names. Place several STUDENT objects into a list and shuffle it. Then run the SORT method with this list and display all of the students' information.arrow_forward
