You will write a method that will take a file name (String) as a parameter that is a file of numbers and will return the sum of the numbers in the file. You will then create a GUI with the following: 1. Some way for the user to specify a file name. 2. A mechanism for the user to begin processing the file. 3. Some place to display the sum of the numbers. You can keep everything in one class and just include the method that processes the file as a static method.

- Open the Palace Solution.sln file contained in the VB2017\Chap10\Palace Solution folder. Use Windows to copy the Rectangle.vb file from the VB2017\Chap10 folder to the Palace Project folder. Then, use the Add Existing Item option on the Project menu to add the file to the project. Modify the Rectangle class to use Double variables rather than Integer variables. Change the name of the GetArea method to GetAreaSqFt. Add another method to the class. Use Get AreaSqYds as the method’s name. The method should calculate and return the area of a rectangle in square yards. The application’s Calculate button should calculate and display the number of square yards of carpeting needed to carpet a rectangular floor. Code the btnCalc_Click procedure. Display the number of yards with one decimal place. Save the solution and then start and test the application.Design a class named CustomerRecord that holds a customer number, name, and address. Include separate methods to 'set' the value for each data field using the parameter being passed. Include separate methods to 'get' the value for each data field, i.e. "return" the field's value. Pseudocode:Create a file with the name car.py to store information about a single Car Class. The Car object needs to include the following information: Car name Car vin number Car make Import the Car class into the main.py. Inside the main portion of the code, create a Car object, car1, that has the name "Car", vin "111", and the make "Honda". Print the car information to the commandline and make sure that your code is working correctly. Create a file with the name linkedlist.py. This file will contain the linked list class and the node class as well. The linkedlist.py file needs to import the Car class Create a class Node to represent a single node in the linked list. The class will be inside the linkedlist.py file. The Node class will include the following: A next pointer to hold the address of the next node. You need to set this variable to None A car variable to hold the car objects. Test your Node class in the main. Create a Car object car1. Set the name of the car, vin, and model Create a…
- 9-10. Imported Restaurant: Using your latest Restaurant class, store it in a module. Make a separate file that imports Restaurant. 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"]In this lab, you will create a programmer-defined class and then use it in a Java program. The program should create two Rectangle objects and find their area and perimeter. Instructions Make sure the class file named Rectangle.java is open. In the Rectangle class, create two private attributes named length and width. Both length and width should be data type double. Write public set methods to set the values for length and width. Write public get methods to retrieve the values for length and width. Write a public calculateArea()method and a public calculatePerimeter() method to calculate and return the area of the rectangle and the perimeter of the rectangle. Open the file named MyRectangleClassProgram.java. In the MyRectangleClassProgramclass, create two Rectangle objects named rectangle1 and rectangle2. Set the length of rectangle1 to 10.0 and the width to 5.0. Set the length of rectangle2 to 7.0 and the width to 3.0. Print the value of rectangle1’s perimeter and area, and then…Create a new Java Application project called lab_07 Part 1: 1. Copy the source file Square class you crated in Lab 03 and paste the source file in the default package (you may need to fix any problems related to package declaration). 2. Open Square class using NetBeans editor. 3. Modify the class implementation to throw IllegalArgumentException if the side’s length is negative. You should modify the implementation of the arguments constructor and setSide method to throw the IllegalArgumentException. Use the following constructor header as a start: /** * Construct a Square object with the specified side’s length * @param side the side’s length of a square * @throws IllegalArgumentException if the side’s length is negative */ public Square (double side) throws IllegalArgumentException { // implement it } Part 2: 1. Write a program that prompts the user to read two integers and displays their sum. Your program should prompt the user to enter the number again if the input is…
- Description is " A MathVector object will be passed to your method. Return its contents as a String. If you look in the file MathVector.java you'll see there is a way to output the contents of a MathVector object as a String. This makes it useful for displaying to the user. You might have noticed that there's an @override term there. That's because many objects already have a "toString()" method associated with them... because Java was designed to include them by default. Here, the override tells Java "I know, I know. You already have a toString() that you'd assign here. But it's not good enough. Here's a better one for this particular kind of object." It's a little bit like saying "Most humans have two legs. So, by default, I'll give everyone two legs. But sometimes we override that and give no legs, or just one leg to a person. And sometimes we give them four so that they can be a centaur!" To use this in a println() method, just name your object. The toString()…A group or collection of objects with common properties is called: a. Class b. Interface c. Method d. AttributesRead the instructions below and write your code using Microsoft Visual Studio (Community version). Build your own console application with C#. Write a Rectangle class, the private data members are the length (len) and width (wid) of the rectangle, the parameterless constructor sets len and wid to 0, and the parameterized constructor sets the value of length (len) and width (wid). In addition, the class also includes common methods such as calculating the perimeter of the rectangle, calculating the area of the rectangle, obtaining the length value of the rectangle, obtaining the width value of the rectangle, and modifying the length and width values of the rectangle to the corresponding formal parameter values. Please upload your executable C# file as attachment in the system.
