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 trying..”).

- Python help please! Thank you! Add the following methods to your Boat Race class: Write a method called add_racer which takes in a Boat object and adds it to the end of the racers list. The function does not return anything. Write a method called print_racers which loops through racers and prints the Boat objects. This function takes in no parameters (other than self) and returns nothing. Write a method called count that returns the number of racers. Write a method called race. The race function calls the move function for all of the racers in the BoatRace. Once all the racers have moved, call the print_racers method to display information about the progress of each boat. Then, check if any of the racer’s current_progress is greater than or equal to the race’s distance. If so, then return a list of all of the racers whose current_progress is greater than or equal to distance. If no racer has finished the race then repeat the calls to move and check until at least one…arrow_forwardAdd the following methods to your Boat Race class: Write a method called add_racer which takes in a Boat object and adds it to the end of the racers list.

- mau Open Leathing inta... - The class has data members that can hold the name of your cube, length of one of the sides and the color of your cube. - The class has a constructor that accepts the name, length of one of the sides, and color as arguments and sets the data members to those values. - The class has the following methods to set the corresponding data member. setName(string newName) setSide(double newSide) setColor(string newColor) - The class has a method called getVolume() that returns the volume of the cube, calculated by cubing the length of the side. - The class has a method called volumelncrease(double newVolume) that receive the percent the volume should increase, and then the side to the corresponding value. i - For example, 2.5 indicates 2.5% increasing of the volume. So you take the current volume, increase it by 2.5%, and then find the cube root to calculate the new side length. You can use the built in function called cbrt, part of the math library, to find the cube…arrow_forwardCreate a class called StatSet that can be used to do simple statisticalcalculations. The methods for the class are:__ init __ ( self ) Creates a StatSet with no data in it.415addNumber ( self , x) x is a number. Adds the value x to the statSet.mean(self ) Returns the mean of the numbers in this statSet.median( self ) Returns the median of the numbers in this statSet.stdDev( self ) Returns the standard deviation of the numbers in this statSet.count ( self ) Returns the count of numbers in this statSet.min(self) Returns the smallest value in this statSet.max (self ) Returns the largest value in this statSet.arrow_forwardIntroduction In this project, you will complete a C++ class by writing a copy constructor, destructor, and assignment operator. Furthermore, you will write a tester class and a test program and use Valgrind to check that your program is free of memory leaks. Finally, you will submit your project files on GL. If you have submitted programs on GL using shared directories (instead of the submit command), then the submission steps should be familiar. In this project we develop an application which holds the information about a digital art piece. There are two classes in this project. • The Random class generates data. The implementation of this class is provided. It generates random int numbers for colors. To create an object of this class we need to specify min and max values for the constructor. The colors fall between 30 and 37 inclusively. The Art class generates random colors and stores the color values. You implement the Art class. An object of the Art class is a digital masterpiece.…arrow_forward

You can test this by checking that the difference between R and S is empty.arrow_forwardJAVA Write a class that calculates add, subtraction, and multiplication. The class should include the following methods: Constructor : initialize all values to 0 getAsk() : Ask users to input two integer numbers. This method calls Distribute() method. Distribute() : Ask users to choose which calculation he/she wants. This method calls a method that can add, subtract, or multiply based on the user's option. CalAdd() : add two numbers CalSub() : subtract two numbers CalProduct() : multiply two numbers toString() : toString method that display result of operation. The program should be designed to test the class developed. Your program might look like the following: public class CalculateNumTesting{ public static void main(String[] args){ CalculateNum calculation = new CalculateNum(); calculation.getAsk(); System.out.println(calculation); } }arrow_forwardUsing oop in java Create a class for Subject containing the Name of the subject and score of the subject. There should be following methods: set: it will take two arguments name and score, and set the values of the attributes. If score is less than 0 or greater than 100.0 then a message should be displayed “Incorrect score” and score should be set to Zero. set: it will take one double value as argument and set the value of score only. If score is less than 0 or greater than 100.0 then a message should be displayed “Incorrect score” and score should be set to Zero. display: it will display the name and score of the subject. Like “Name : Math, Score: 99.9” getScore: it will return the value of score. greaterThan: it will take subject’s object as argument, compare the calling object’s score with argument object’s score and return true if the calling object has greater score.arrow_forward
