Exercise 11:0 (20)Write a Java class that implements a set of three overloaded static methods. The methods shouldhave different set of parameters and perform similar functionalities. Call the methods within mainmethod and display the results.Lab #2Java ProgrammingExercisDesign a Lo class with one array instance variable to hold three random integer values (from 1to 8). Include a constructor that randomly populates the array for a lotto object. Also, include amethod in the class to return the array.Exercise 3 (F...!Page 1 of 3Use this class to simulate a simple lotto game in which computer randomly chooses a numberbetween 3 and 24. The user runs the lotto up to 7 times and each time the sum of lotto numbersentered by the user is calculated. If the sum of the numbers chosen by the user matches the numberselected by computer, the user wins and the game ends. If the sum of the entered numbers does notmatch the sum within 7 rolls, the computer wins. Use methods of JOptionPane class to interactwith the user.COMP-228Write a Java application that simulates a test. The test contains at least 3 questions about first threelectures of this Java course. The 3 questions should be randomly selected from a bank of at least6 questions without repetition. 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 - generateQuestioncreate a method check the answer - checkAnswercreate a method to display a random message for the user-generate Messagecreate a method to interact with the user - inputAnswerDisplay 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 trying..").Use random-number generation to choose a number from 1 to 4 that will be used to selectan appropriate message.Use a switch statement to issue the responses, as in the following code:switch (randomObject.nextInt( 4 )){case 0:return("Very good!");At the end of the test display the number of correct and incorrect answers, and the percentage ofthe correct answers.Your main class will simply create a Test object and start the test by calling inputAnswer method.

C++ Programming. General setting. The program must contain: • base class X, which includes two elements x1, x2 of type int, • constructor with parameters for creating objects in dynamic memory area, • destructor, • virtual methods for viewing the current state and reinstalling base class objects to a new state. • derived class Y, including one element y of type int , • a constructor with parameters and an initializer list, passing data to the base class constructor, • overridden methods for viewing the current state of objects and reinstalling them to a new state. Create a Run method in the derived class that defines: Value (x1-x2)^2/y

Question 5 (6 marks) Given the following interface class interface Bigoperation { public Biglnteger operation (Biglnteger x, Biglnteger y); Write Lambda expressions to implement BigOperation to simulate three arithmetic operations *, / and % on Biglnteger. You can call them op1, op2 and op3 respectively. Note that the three operations in Biglnteger are called multiply, divide and remainder respectively. Using these three operations, we wish to multiply all the digits in a Biglnteger. For example, if the Biginteger is 234, the product is 2* 3*4 = 24. The method has the following method heading: static BigInteger product (Biglnteger n, BigOperation op1, BigOperation op2, BigOperation op3) Compare the implementation of this method using two approaches: Iterative and Recursive. Put the Lambda expressions in a main method. Construct a few Biglnteger objects, invoke the methods to test our design. The following shows some of the sample outputs:
[JAVA] Question 4: Write the source code of the classes ReportCurrentRevenue and ReportPastIncome. The ReportCurrentRevenue class is responsible from calculating the current amount of money to be gained if all the guests would leave from the hotel. The ReportPastIncome class is responsible from calculating the money gained so far from the previous visits of guests. Class Hotel will create one instance of this class and execute it in multithreaded fashion in its report method. You will code Hotel.report in the next question. Question 5: Write the source code of only the following methods of the class Hotel. The explanations of the methods you need to code are given below. Don’t forget to address the multithreading issues when coding. report: The details of this method are given in Question 4. restore: This method loads the Hashtable members and LinkedList visits from the path given by the fileName parameter. However, if there are ongoing multithreaded operations, it must first wait…
