- A mountain climbing club maintains a record of the climbs that its members have made. Information about a climb includes the name of the mountain peak and the amount of time it took to reach the top. The information is contained in the ClimbInfo class as declared below. The ClimbingClub class maintains a list of the climbs made by members of the club. The declaration of the ClimbingClub class is shown below. You will write implementations of the addClimb method. import java.util.List; import java.util.ArrayList; class ClimbInfo { private String name; private int time; /** Creates a ClimbInfo object with name peakName and time climbTime. * * @param peakName the name of the mountain peak * @param climbTime the number of minutes taken to complete the climb */ public ClimbInfo(String peakName, int climbTime) { name = peakName; time = climbTime; } /** @return the name of the mountain peak */ public String getName() { return name; } /** @return the number of minutes…Write 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.in python. For this project, you will import the json module. Write a class named NobelData that reads a JSON file containing data on Nobel Prizes and allows the user to search that data. Your code does not need to access the internet. Your class should have: an init method that reads the file and stores it in whatever data member(s) you prefer. Any data members of the NobelData class must be private. a method named search_nobel that takes as parameters a year and a category, and returns a sorted list (in normal English dictionary order) of the surnames for the winner(s) in that category for that year (up to three people can share the prize). The year will be a string (e.g. "1975"), not a number. The categories are: "chemistry", "economics", "literature", "peace", "physics", and "medicine". For example, your class could be used like this: nd = NobelData() nd.search_nobel("2001", "economics")
- This C++ assignment is about a grid writer. In this part of the assignment you will not need to write any code. Instead you will download a software project and submit your answers to questions about the code. The project uses a class named GridWriter to display circles and rectangles in a text grid. The GridWriter class is a collection type class similar to an IntCollection. It stores Circle and Rectangle objects that inherit from a base class named Shape. The GridWriter class has a member function named display that accepts a row count and column count as arguments, and prints out a text grid that shows the shapes that it stores. Consider the main function below. It creates a GridWriter, adds some shapes, and then displays a grid: int main() { GridWriter gw; // Add some circles... gw.add(new Circle(10, 10, 9)); gw.add(new Circle(25, 20, 12)); gw.add(new Circle(25, 20, 5)); // Add a rectangle... gw.add(new Rectangle(40, 0, 10, 10)); //…9-10.

Make a Restaurant instance, and call one of Restaurant’s methods to show that the import statement is working properly. 9-13. Dice: Make a class Die with one attribute called sides, which has a default value of 6. Write a method called roll_die() that prints a random number between 1 and the number of sides the die has. Make a 6-sided die and roll it 10 times. Make a 10-sided die and a 20-sided die. Roll each die 10 times. 9-14. Lottery: Using the list called series, write a function called get_winning_ticket_number that randomly select four numbers and four letters from the list. Create a list called winning_ticket_list which contains 10 winning ticket numbers. Print this list. series = ["0","1","2","3","4","5","6","7","8","9","A","B","C","D"]Java Programming: Below is the lexer, shank and token files along with the shank.txt file.

- Introduction 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.…subject:internet fundamentals and scripting Make a Polling game.

- In python 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 racer has finished the race.

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.
