- Write a JAVA program that converts a number entered in Roman numerals to decimal. Your program should consist of a class named Roman, and an object of type Roman should do the following:a) Store the number as a Roman numeral.b) Convert and store the number into decimal.c) Print the number as a Roman numeral or decimal number as requested by the userThe decimal values of the Roman numerals are:• M 1000• D 500• C 100• L 50• X 10• V 5• I 1d) Your class must contain the method romanToDecimal to convert a Roman numeral into its equivalent decimal number. Use the class name “LastnameClasscodeFinal2”.Please use java only. In this assignment, you will implement a simple game in a class called SimpleGame. This game has 2 options for the user playing. Based on user input, the user can choose to either convert time, from seconds to hours, minutes, and seconds, or calculate the sum of all digits in an integer. At the beginning of the game, the user will be prompted to input either 1 or 2, to indicate which option of the game they want to play. 1 will indicate converting time, and 2 will indicate calculating the sum of digits in an integer. For converting time, the user will be prompted to input a number of seconds (as an int) and the program will call a method that will convert the seconds to time, in the format hours:minutes:seconds, and print the result. For example, if the user enters 6734, the program will print the time, 1:52:14. As another example, if the user enters 10,000, the program should print 2:46:39. For calculating the sum of digits in an integer, the user will be…Write a complete Java program that performs the following tasks: Ask the user to enter the last two digits of his/her student ID. Break the number into two digits using arithmetic operators, then store the first and second digits in integer variables named digit1 and digit2 Find and print the following: The product of digit1 and digit2. The sum of digit1 and digit2 The average of digit1 and digit2 The maximum of the two numbers; digit1 digit2 using a method from the class Math. Note: The class name of your Java program must be your first name. Your answer should have the code as text as well as the screenshot of the program output (using your own student ID) as a part of your answer. Otherwise, zero marks will be awarded.
- I need help with this. Thanks in advance It might not be reasonable to expect users to type long entries such as “oil change” accurately. Implement the CarCareChoice2 class so that as long as the user enters the first three characters of a service, the choice is considered valid.

This program will display a menu with the following options: (1) add, (2) subtract, (3) multiply, (4) divide (5) mod, and (6) do nothing. If the user enters something else, the program should display an error message. Otherwise, it should ask the user for two numbers.) Give the output of the following Java program.class Test{ public static void main (String args[]) { System.out.println(10 + 20 + "Javatpoint"); System.out.println("Javatpoint" + 10 + 20); }}d) There are rules that should be followed by identifiers, better known as namingconventions. Identify FOUR ways of such rules in declaring a class. e) Write a syntax for public class. f) Give the output of the following Java program. class Test{ public static void main (String args[]) { for(int i=0; 0; i++) { System.out.println("Hello Javatpoint"); } }}
- Write a program that converts a number entered in Roman numerals to a positive integer. Your program should consist of a class, say, roman type. An object of type roman type should do the following: a.Store the number as a Roman numeral. b.Convert and store the number as a positive integer. c.Print the number as a Roman numeral or positive integer as requested by the user. The integer values of the Roman numerals are: M 100 D 500 c 100 L 50 x 10 v 5 I 1 d. Test your program using the following Roman numerals: Mcxiv, Ccclix, and Mdclxvi.Write a complete Java program that does the following: Ask the user to enter the last number and the second last number of his / her student ID. Stores the entered numbers in adequate variables. Finds and prints the following using "printf": The sum of the two numbers. The boolean value of comparing the equality of the two numbers using the equality operator. The value of the first number is raised to the power of the second number using a method from the class Math. Note: The class name of your Java program must be your first name. Your answer should have the code as text as well as the screenshot of the program output (using your own student ID) as a part of your answer. Otherwise, zero marks will be awarded.

- In java, create a program that gathers user input and prints a paystub. This assignment requires one class per .java file, total of three classes. The first one is employee.java which gathers the user's id (fixed value), first name, last name, address, city, zip, phone, email, and hourly rate. The second one is payperiod.java, which gathers the user's hours worked (taking overtime into account), start date (fixed), end date (fixed), and paystub id (fixed). The third one is payrollmanager.java, which calculates and displays the data gathered from the first two. This class/file should also use methods such as: doubleCalculateGrossPay(Employee, PayPeriod), double CalculateRegularPay(Employee, PayPeriod), double CalculateOvertimePay(Employee, PayPeriod), and void PrintPaystub(Employee, PayPeriod).Implement the below pseudo-code in a Java program using a while loop and aswitch-case statement. The program should be well structured, and the taskperformed under each option (at least options 'b' to 'e') should be implementedas a separate method.NOTE: The Scanner class does not have a method to input a character. Inorder to read a character from the keyboard, use one of the following methods(after declaring the Scanner object):static Scanner kb = new Scanner(System.in);1. char ch = kb.nextLine().charAt(0); OR2. char ch = kb.nextLine().toLowerCase().charAt(0);where kb is a Scanner class object.The second method above also converts the input to lowercase, which is oftenuseful. Though these methods allow the user to input more than one characteron the input line, the rest of the line (after capturing the first character withcharAt(0)) is discarded.If you also want to ignore the leading spaces before the first character thenuse:1. char ch = kb.nextLine().trim().charAt(0); OR2. char ch =…Write a complete java program for the following narrative: You were hired by PAGCOR as part of the programming team in-charge of automating its BINGO game.
