- DescriptionIn this assignment, you are required to implement an electronic programming quiz system. User can createquestions and preview the quiz.Your TaskYou are asked to write a Java program for the programming quiz system. There are two types of questions:Multiple Choice Question and Ture/False Question. User can create questions using the system; andpreview the quiz, which display all questions in the system one by one. During the preview, the user canattempt the quiz by entering his/her answers to questions. The system will then immediately check theanswer and calculate. After attempting all questions, the total score will be displayed. A sample run of theprogram is shown as below (Green text refers to user input): Please choose (c)reate a question, (p)review or (e)xit >> cEnter the type of question (MC or TF) >> MCEnter the question text >> Each primitive type in Java has a correspondingclass contained in the java.lang package. These classes are called…Java Programming: Below is the lexer, shank and token files along with the shank.txt file. The shank file is the main method file. The lexer must break up the input text stream into lexemes and return a token object for each one in the shank.txt file. Make sure to fix the errors in the lexer.java file and show the complete code for lexer.java.There must be no error in the code at all. Run the whole code and show the output which the shank.txt must be printed out in the terminal. Attached is the rubric.

The main program will start by calling a method named introduction() which will print out a description of what the program will do at the top of the first output page. This first method is called just once. This method will not be sent any parameters, and it will not return a value. It will print several lines of output explaining what the program does, and it will explain how the program should end (see step 4). 1. The main program will ask the user to type in three integer values, positive, negative, or zero (see step 4). The main program will print the three numbers right after they are read in. 2. The main program will call a method named findsum(), sending it the three integer values. The method will determine the sum of the larger 2 of the three values, sending the answer back to the main program. The main program will…
- UOWD Library is asking you to write a Java program that manages all the items in the Library. The library has books, journals, and media (DVD for example). All items have a name, author(s), and year of publication. A journal also has a volume number, while a media has a type (audio/video/interactive). The user of your program should be able to add an item, delete an item, change information of an item, list all items in a specific category (book, journal, or media), and print all items (from all categories). A menu asks the user which operation s/he wants to perform. Important: make use of collections, inheritance, interfaces, and exception handling wherever appropriate.Java RMI modify “MyClient.java”, “Method.java” and “MethodRemote.java” After your modification, re-compile, and run server and client programs, the client asks the user to enter a string. • If a string “time” is entered, the client will get current date and time from server by remotely invocating the method “action()” in server machine. • If another string other than “time” is entered, then the client will get the capitalized version of the string the user just entered by remotely invocating the method “action()” in server machine. • Your client program should keep asking the user’s input for a string unless an empty string is entered (i.e., just press ENTER key without anything else). When an empty string is entered, this client will quit. while a client is being connected to the server, the server should be able to receive new clients’ connections for current date/time or capitalized strings. In other words, the server should concurrently handle multiple clients’ connections and…1)The program should be written in JAVA. Create a "Car" class that keeps car ids and prices. And create a "Galleries" class that holds the car list for a particular gallery. In this class there should be methods for get / set and print for car name, car number and car list. Adding / Removing Cars to the List in This Class should have methods. And create another method to find and print the IDs of Cars with Car Segment equal to X. (print_id(X)). Car Prices are as follows according to the segments. 0$-19999$ -> Z20000$-29999$ -> Y30000$-44999$ -> T45000$-100000$ -> P Apply the Car list using "Singly Linked List"(Node, newNode, head).
- Basic Java Help Each year, the Social Security Administration provides a list of baby names for boy and girls by state. You will write a program to read a file containing a list of baby names and display the top names. To start, implement the following class: baby names util = printTopNames(File, int): void printTopNames Will be a static method. It will accept two parameters, one is a File containing the list of names. The other is an integer that indicates how many names to display (ie, top 10 names, or top 50 names, etc). The integer argument could be any valid integer. You do not have to worry about an integer value large than 5 for the boy/girl names. This method should open the file and parse the file and print the names as shown below: Your program will use the Scanner class to read the data from the file (see your text for examples). You will also need to use a delimiter with the scanner so that the scanner will break the line apart based on the commas. For this file, set…Write a program namedAveragesthat includes a method that accepts any number ofnumeric parameters, displays them, and displays their average. Demonstrate that theprogram works correctly when passed one, two, or three numbers, or an array ofnumbers.FOR JAVA Write a Java class named Book, which has a name, an author and a pub- lisher. This class must also have a static field (an array with length 100) which holds names of all constructed books, and a static method which returns the number of constructed books. You must also implement its constructors (one constructor with parame- ters, one default constructor), toString method, getters and setters.
- An array of class objects can be created in Java. False or TrueWrite an application TestStudent that prompts for and reads a student name. It then creates a Student object. It then prompts for and reads the number of quizzes n that the student has taken. It then prompts for and reads the scores of the student in n quizzes and adds each to the totalScore of the student using addQuiz() method. Finally, the application prints the student object using the toString() method, and it also prints his quiz average. The main method must handle java.util.InputMismatchException, java.lang.IllegalArgumentException and java.lang.Unsupported OperationException.FOR JAVA Write a Java class named Book, which has a name, an author and a pub- lisher.
