Write a java program that uses an ArrayList object to store the following set of names in memory:
[Steve, Tim, Lucy, Pat, Angela, Tom]
Now write some more code so that the same ArrayList object is augmented with the name 'Steve' after the name 'Lucy'
After the ArrayList object has been augmented with the new name, display the original and new lists on the console (as shown below), to verify that the new name is positioned correctly in the list.
Provide a different implementation of ChoiceQuestion. Instead of storing the choices in an array list, the addChoice method should add the choice to the question text. For this purpose, an addLine method has been added to the Question class.
Use the following files:
Question.java
/** A question with a text and an answer.*/public class Question{ private String text; private String answer;
/** Constructs a question with empty text and empty answer. */ public Question() { text = ""; answer = ""; }
/** Sets the answer for this question. @param correctResponse the answer */ public void setAnswer(String correctResponse) { answer = correctResponse; }
/** Checks a given response for correctness. @param response the response to check @return true if the response was correct, false otherwise */ public boolean checkAnswer(String response) { return response.equals(answer); }
/** Add a line of text to…
We know that the first file name is stored at index zero in the ArrayList, and the list stores the file names as strings, so could we write the body of listAllFiles along the following lines? System.out.println(files.get(0)); System.out.println(files.get(1)); System.out.println(files.get(2)); etc. How many println statements would be required to complete the method?

- Write a Program in Java programming: Support you have an ArrayList containing random integers. These integers can be any number, and each integer can appear more than once. For example, [2, 19, 21, 19, 21, 1, 3, 3, 6, 21, .....] Your job is to write a method called findEvenFrequentNumbers(ArrayList<Integer> list) that returns an ArrayList which has all the numbers appears in even frequency and in increasing order. e.g. list = [2, 19, 21, 19, 21, 1, 3, 3, 6, 21], should return [3, 19] list = [3, 3, 3, 1, 2, 2, 2, 2, 2], should return [] list = [1, 1, 1, 1, 1], should return [1] Note that you need to provide a class with the main function and also the imports.arrow_forwardUsing the picture, ultilize Java to design a container class and implement the class PascalTriangle that will generate a Pascal Triangle from a given number of rows. Please represent each row in a triangle as a list and the entire triangle as a list of these lists, implement the class ArrayList for these lists. Inside this Java container class, develop a method called getChoice that takes in two parameters n and k (where n is the number for row and k is the position) and returns the integer value of C(n, k). For example, getChoices (5, 2) will return 7.arrow_forwardWrite a program in which you create an object of type ArrayList named BZ and then add 3 elements in this object and then copy the elements of the object in another object QZ and then cancel the elements of the object BZ and then write the necessary print statements to show it? in javaarrow_forward
- Implement the Plates class buildMap function so that it populates the HashMap with the state abbreviations as keys and the counts of how many each appear in the file as values. Sometimes, the parking attendant will add special notation to help her remember something about a specific entry. There are just non alphabetic characters that she adds to the state - your program should ignore these characters so that an entry like NY* still counts toward the NY plate count. She is also very inconsistent with how she enters the plates. Sometimes she uses upper case, sometimes lowercase, and sometimes she even uses a mix. Be sure to account for this in your program. Only add information for plates in New England (Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, and Connecticut).

Given classes: Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. (Hint: toString() returns a String representation of the Student object.) Ex: If the following students and their GPA values are added to a course: Henry Cabot with 3.5 GPABrenda Stern with 2.0 GPAJane Flynn with 3.9 GPALynda Robison with 3.2 GPA then the program output is: Henry Cabot (GPA: 3.5) Brenda Stern (GPA: 2.0) Jane Flynn (GPA: 3.9) Lynda Robison (GPA: 3.2) Students: 4 course.java import java.util.ArrayList; // Class representing a studentpublic class Course { private ArrayList<Student> roster; // Collection of Student objects public Course() {…arrow_forward
- write a program that reads the students.txt file and stores the name of the student and the grade information as a student object in an arraylist sorts the students names based on their first grade in decreasing order using the selection sort algorithm writes the sorted list as the students last name , middle name (if theres one), first name , and grade information into a text file output example: Robison, Lee 95 80 Green, Alex R 85 60 Waston, Zoe G 100 80 use javaarrow_forwardYou are given an ArrayList of ArrayLists, Each inner ArrayList Contains Integers.

Include getters and setters for these fields. Implement the Comparable interface for Vehicle class and override the compareTo() method to compare vehicles based on their milesPerGallon. Create a main class (for example, VehicleDriver.java) to handle user input and perform the necessary operations. Inside the main method, create a BufferedReader object for user input. Prompt the user to enter the number of vehicle data they want to enter and store it in a variable (for example, nVehicles). Use a loop to iterate nVehicles times and prompt the user to enter make, model, and miles per gallon for each vehicle. Create Vehicle objects using the input data…arrow_forward
- Write a Java program that would resemble banking transactions of deposits, withdrawals, bank to bank transfers, and interest computations. A transaction input window is to be used in entering the account number, transaction code, and amount. Search a 2d-arraylist containing account number and the current balance, and then do the appropriate update on the 2d-arraylist depending on the transaction code. If the transaction code is “D”, update the current balance by adding the amount; if “W”, update the current balance by subtracting the amount from the current balance provided that withdrawal transaction is allowed (current balance must be greater than the amount to be withdrawn, and the resulting balance must not be less than 500). Display the updated 2d-arraylist before exiting the program. Design your own input/output windows.

And What was the advantage of using the iterator ? import java.util.Iterator String[ ] originalData = { "one", "two", "three", "four", "five" }; List<String> strings = new ArrayList<>(Arrays.asList(originalData)); for ( int i=0; i<strings.size(); i++) { // process strings.get(i): here, just printSystem.out.println(strings.get(i));}arrow_forwardWe want to write a Java program to encode a name by creating an array of integers. Write Java method called encodeName that takes a name as a string (without spacing and all lower case) and returns an array of integers of the same size as name whose elements are the number in the alphabet of the corresponding character in name (starting from zero). For example, calling this method with name = “aabed” it should return [0, 0, 1, 4, 3]. Write a printArray method that prints all the elements of an array of integers in one line. Write a main method that calls encodeName and printArray methods to print the array corresponding to your name. * i need this program to work on natebeansarrow_forward
