- Question 8 mee bookRoom(Room) takes a Room as an argument and searches the rooms list for a room with a matching number. If a match is found, the hotel room concerned has its guest field set to a dummy value "Guest". If no match is found the method does nothing. (Assume that room numbers are unique.) Full explain this question and text typing work only thanksRules: Corner cases. By convention, the row and column indices are integers between 0 and n − 1, where (0, 0) is the upper-left site. Throw an IllegalArgumentException if any argument to open(), isOpen(), or isFull() is outside its prescribed range. Throw an IllegalArgumentException in the constructor if n ≤ 0. Unit testing. Your main() method must call each public constructor and method directly and help verify that they work as prescribed (e.g., by printing results to standard output). Performance requirements. The constructor must take Θ(n^2) time; all instance methods must take Θ(1)Θ(1) time plus Θ(1)Θ(1) calls to union() and find().True or False? Arrays cannot be passed as parameters, but must be used only in the main method.
- void Date: addDays (int n); void Date: subtractDays(in n); The addDays method will add n number of days to the current date that's stored in Object's data. For example, object hold 4/21/2022 as the date and if user of this object calls addDays (10) method, it will add 10 days to 4/21/2022 giving a new date of 5/1/2022. There can be more complicated scenarios if you add a lot of days (for example hundreds of days) due to possible rollover of year and months. You can limit number of days to be added to 100. Just like addDays, subtractDays method will subtract number of days from the current date. Provide implementation of both functions in the class. Also modify your main function as follows:Eclipise Exercise 1: Write a Java application that simulates a test. The test contains at least five questions about first three lectures of this course. Each question should be a multiple-choice question with 4 options. Design a Test class. Use programmer-defined methods to implement your solution. For example: create a method to simulate the questions – simulateQuestion create a method to check the answer – checkAnswer create a method to display a random message for the user – generateMessage create a method to interact with the user - inputAnswer Display the questions using methods of JOptionPane class. Use a loop to show all the questions. For each question: If the user finds the right answer, display a random congratulatory message (“Excellent!”,”Good!”,”Keep up the good work!”, or “Nice work!”). If the user responds incorrectly, display an appropriate message and the correct answer (“No. Please try again”, “Wrong. Try once more”, “Don't give up!”, “No. Keep…All methods in this class are public. -int ID -name -status (int ID, String name, String status) setiD (int ID) setName (String name) setStatus (String status) getName) string getStatuso toString0 Pick one: True/False
- Create an automobile class that will be used by a dealership as a vehicle inventory program. The following attributes should be present in your automobile class: private string make private string model private string color private int year private int mileage Your program should have appropriate methods such as: default constructor parameterized constructor add a new vehicle method list vehicle information (return string array) remove a vehicle method update vehicle attributes method. All methods should include try..catch constructs. Except as noted all methods should return a success or failure message (failure message defined in "catch"). Create an additional class to call your automobile class (e.g., Main or AutomobileInventory). Include a try..catch construct and print it to the console. Call automobile class with parameterized constructor (e.g., "make, model, color, year, mileage"). Then call the method to list the values. Loop through the array and print to the screen.…Part 2. fill Method Define a method in simpy named fill. Its purpose is to fill a simpy's values with a specific number of repeating values. The fill method will have two parameters following self: 1. The float value you are filling the values list in with. 2. The int number of values to fill in. The fill method is procedure-like in that it returns None and mutates the object the method is called on. After calling fill, the length of the Simpy object's values should be equal to the second argument given to fill. For example, consider the following usage and expected printed output, given inline, below: twos = Simpy([]) twos.fill(2.0, 3) print("Actual: ", twos, Expected: Simpy([2.0, 2.0, 2.0])") twos.fill(2.0, 5) print("Actual: ", twos, " - Expected: Simpy([2.0, 2.0, 2.0, 2.0, 2.0])") mixed = Simpy([]) mixed.fill(3.0, 3) - Expected: Simpy([3.0, 3.0, 3.0])") print("Actual: ", mixed, mixed.fill(2.0, 2) print("Actual: ", mixed, Expected: Simpy ([2.0, 2.0])") PythonValue-returning methods must pass parameters. -True or -False
- Ag 1- Random Prime Generator Add a new method to the Primes class called genRandPrime. It should take as input two int values: 1owerBound and upperBound. It should return a random prime number in between TowerBound (inclusive) and upperBound (exclusive) values. Test the functionality inside the main method. Implementation steps: a) Start by adding the method header. Remember to start with public static keywords, then the return type, method name, formal parameter list in parenthesis, and open brace. The return type will be int. We will have two formal parameters, so separate those by a comma. b) Now, add the method body code that generates a random prime number in the specified range. The simplest way to do this is to just keep trying different random numbers in the range, until we get one that is a prime. So, generate a random int using: int randNum = lowerBound + gen.nextInt(upperBound); Then enter put a while loop that will keep going while randNum is not a prime number - you can…Please help me with this , I am stuck ! thanks 1) bagUnion: The union of two bags is a new bag containing the combined contents of the original two bags. Design and specify a method union for the ArrayBag that returns as a new bag the union of the bag receiving the call to the method and the bag that is the method's parameter. The method signature (which should appear in the .h file and be implemented in the .cpp file is: ArrayBag<T> bagUnion(const ArrayBag<T> &otherBag) const; This method would be called in main() with: ArrayBag<int> bag1u2 = bag1.bagUnion(bag2); Note that the union of two bags might contain duplicate items. For example, if object x occurs five times in one bag and twice in another, the union of these bags contains x seven times. The union does not affect the contents of the original bags. Here is the all of the file: ArrayBag.cpp: #include <string>#include "ArrayBag.h" template <class T>ArrayBag<T>::ArrayBag() :…Complete the following method, whose purpose is to subtract the value of its parameter from a field named price. /** * Reduce price by the given amount. */ public void discount(int amount) { ... }
