Multiple choice in java Given the following code snippet: ArrayList shapes = new ArrayList<>(); Scanner scan1=new Scanner(new File("D:\\AAUJ\\AAA\\radiusInfo.txt")); //This statement is equivalent to Scanner scan1=new Scanner(new FileInputStream("D:\\AAUJ\\AAA\\radiusInfo.txt")); while(scan.hasNext()) { double radius; scan.next(); radius=Double.parseDouble(scan.next()); shapes.add(new Circle(radius)); } Select one: a. The compiler will report an error if Shape class does not extend Circle class b. The compiler will report an error

JAVA PPROGRAM Write a program that prompts the user to enter a file name, then opens the file in text mode and reads names. The file contains one name on each line. The program then compares each name with the name that is at the end of the file in a symmetrical position. For example if the file contains 10 names, the name #1 is compared with name #10, name #2 is compared with name #9, and so on. If you find matches you should print the name and the line numbers where the match was found. While entering the file name, the program should allow the user to type quit to exit the program. If the file with a given name does not exist, then display a message and allow the user to re-enter the file name. The file may contain up to 100 names. You can use an array or ArrayList object of your choosing, however you can only have one array or ArrayList. Input validation: a) If the file does not exist, then you should display a message "File 'somefile.txt' is not found." and allow the…
This question comes from the textbook:Starting out with Visual C# 5th Edition - Chapter 14 Programming Problem 2 Create an application that reads the contents of two text files and uses LINQ extension methods to perform the following: • It should display a list of all the unique words contained in both files.• It should display a list of the words that appear in both files.• It should display a list of the words that appear in the first file but not the second.• It should display a list of the words that appear in the second file but not the first.• It should display a list of the words that appear in either the first or second file but not both. Hint: Use set operations to perform these analyses. Also, see Chapter 8 for a discussion of string tokenizing.

java program that Creates an INDEXCEPTION value of the unique vowels and unique consonants that the name that was given to you can create.Input: A string of the name that was GIVEN TO YOU. CASE SENSITIVE.Process1: For every unique vowel of a name, you need to get the first index of that vowel from the original string. 2: For each vowel index you get from step 1, you will get the unique consonant from that position. if the index is out of scope of the consonant array, ignore that vowel index. 3: For each unique consonant that you get from step 2, you need to get the first index of that consonant from the original string. 4: Get the value of indexception by adding all index you get from step 3.OutputTO BE DISPLAYED- 2 lists that consists of unique vowels and unique consonants- The vowel, the vowel index, the consonant, the consonant indexFINAL OUTPUT- The total indexception value of the name that was given to you.
IN C++ Write a program that represents a playlist on a video streaming service. Each video has a title and total minutes. The user should be able to do the following with the playlist: Add video to list Remove video from list Display list in alphabetical order by title Exit playlist Your driver file will need a storage object that can handle any amount of videos. You will also need to provide a menu that shows and performs the various options above. The menu should continue to display until the user selects the "Exit playlist" option. A description of each menu option is listed below: Add video to list Prompts the user for a video title and total minutes Then your code stores the video onto the storage object of your choice Remove video from list Prompts the user for a video title Then your code removes that video from your storage object Display list in alphabetical order Displays the video's title and total minutes for each video in your storage object.

PHONE DIRECTORYDescription: Create a phonebook directory that will store the contact numbers of N persons. Your program should allow the user to add, view, delete, and update the contacts in the phonebook. Note that one person can have multiple contact numbers. The program will stop when the user command is ‘X’. Program command and entry should not be case-sensitive. That means commands ‘I’ or ‘i’ and the name “Jacky” or “JACKY” are the same. Each contact number can be 7 digits or 11 digits only. The user should input a string containing the command, name, and contact number(s) (Limit the contact number of each person to three). This string should be broken down into fields in order to separate the different values and store them in their appropriate variables. Use linked list in the implementation. Your node must declare at least four instance variables. Program flow: Command> I Jacky 09211234567 Remarks: New contact has been added. Command> V Jacky Contact…
createDatabaseOfProfiles(String filename) This method creates and populates the database array with the profiles from the input file (profile.txt) filename parameter. Each profile includes a persons' name and two DNA sequences. 1. Reads the number of profiles from the input file AND create the database array to hold that number profiles. 2. Reads the profiles from the input file. 3. For each person in the file 1. creates a Profile object with the information from file (see input file format below). 2. insert the newly created profile into the next position in the database array (instance variable).
When it loads, the list of car objects should be created by reading from the above file. When Add Car button is clicked the following screen should appear: a Add a New Car Model: Year: Çolor. Mleage: Cancel Add When the user fills out new car information and clicks "Add", the new car object is created, the form is closed, so that the main form is shown again, and the newly created car object is added to the list of cars. When "View cars" button is clicked, the following form shows, displaying all car objects currently in the list (use Getlotel) function here. You will also have to send the list of cars from the main form to tis form. To do this in the view form have a public variable for list of cars, and assign to it the list of cars from the main form). ag View Cars Model: Accord, Year.20166 Year. 20166, Color: Blue, Mieage: 0 Model: Passat, Year:2014 Year: 2014, Color: White, Mileage: 20000 Close
