Design a class named MyPoint to represent a point. The class contains: ➤ Two double private data fields named x and y that specify the coordinates of a point. ➤ A pubic no-arg constructor that creates a default point (0, 0). ➤ A pubic constructor that creates a point with specified x and y coordinates. Two sets of pubic get and set methods for the two private data fields. Write a test class named Lab8 with a main method to create a 2 by 3 array filled with points¹ as follows: (0.5, 1.2) (0.0, 3.14) (6.6, 7.7) (1.2, 2.1) (15.0, 27.5) (12.0, 127.0) In your main method, use a pair of nested for-loops to print the contents of the array. Your output should appear as below:

Create the StockTask1 Java project Create a Stock object class that contains the following information: The symbol of the stock is stored in a private string data field called symbol. The stock's name is stored in a private string data field called name. previousClosingPrice is a private double data area that stores the stock price for the previous day. currentPrice is a private double data area that stores the stock price at the current time. A constructor for creating a stock with the given symbol and name. For the data fields, there are accessor methods (get-methods). For the data fields, there is a mutator method (set-methods). A method named getChangePercent()that returns the percentage changed from previousClosingPrice to currentPrice. Formula:perc_change = (current price - previous closing price) / previous closing price x 100 Create a test class named testStockthat creates a Stockobject with the stock symbol SUNW, the name Sun Microsystems Inc., and the previous closing…
Create a BowlingTeam class The class has 2 fields: a field for the team name and an array that holds the team members’ names. Create get and set methods for the teamName field. Add a setMember method that sets a team member’s name. The method requires a position and a name, and it uses the position as a subscript to the members array. Add a getMember method that returns a team member’s name. The method requires a value used as a subscript that determines which member’s name to return. Create a BowlingTeamDemo class. In the main method include the following: Declare 2 variables: name and a constant NUM_TEAMS that holds 4 Bowling Team objects. Declare and instantiate an array teams of BowlingTeam objects. Using nested for loops, prompt the user to enter the 4 team names and enter the team members’ names. Using another nested for loop, output each team’s name and their team members’. Output should look like: Members of team The Lucky Strikes Carlos Diego Rose Lynn Members of team I…

Rectangle Object Monitoring Create a Rectangle class that can compute the total area of all the created rectangle objects using static fields (variables). Remember that a Rectangle has two attributes: Length and Width. Implement the class by creating a computer program that will ask the user about three rectangle dimensions. The program should be able to display the total area of the three rectangle objects. For this exercise, you are required to apply all OOP concepts that you learned in class. Sample output: Enter Length R1: 1 Enter Width R1: 1 Enter Length R2: 2 Enter Width R2: 2 Enter Length R3: 3 Enter Width R3: 3 The total area of the rectangles is 14.00 Note: All characters in boldface are user inputs.
StockReader Class • This class will contain the method necessary to read and parse the .csv file of stock information. • This class shall contain a default constructor with no parameters. The constructor should be made private. . This is to prevent the class from being instantiated since the class will only contain static methods. • This class shall contain no data fields. • This class shall have a method called readStockData: . This method shall be a public, static, method. . This method shall return a StockList object once all data has been processed. . This method will take a File object as a parameter. This File object should link to the stock market data in your files folder created previously. . This method must validate that the given File object is a .csv file. If it is not, then this method shall throw an IllegalArgumentException. . This method shall read the File object and process all of the stock data into TeslaStock objects and store each object in a StockList. NOTE: The…
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.…
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…
