- Java Code Write a Windspeed class that stores the total winsoeed for each of 12 months into an array of double windspeedmeasures. The windspeed shoukd be collected from the user. The program should have methods that return the following: - total windspeed fir the year - the average monthly windspeed (Include single line comments and populating the array with a Scanner)1. Square Roots Create a class with a method that, given an integer, returns an array of double-precision floating point numbers (known in Java as double), each of which is a square root of a number between 2 and the parameter to the method. For example, if the parameter is 5, the method should return an array of 4 doubles, with approximate values 1.4142135623, 1.7320508075, 2.0, and 2.2360679774. Your method should check the validity of the parameter, and take appropriate action if the parameter is invalid. 2. Reading Files Create a class with a method that, given a string representing a file name, returns an integer with the number of characters in the file. For example, if the file has 10 characters, your method must return the number 10. 3. Main Class Create a class HW1.java with a main method that does both of the following: calls the method from part 1 with a random integer between 0 and 10, and prints each of the numbers in the result. The numbers should all be printed on the…Java - Access Specifiers Create a class named Circle that has attributes radius, area, and circumference and make the attributes private. Make a public method that sets the radius and a method that prints all attributes. Ask the user input for radius. Note: Use the PI from the math functions Inputs A line containing an integer 10 Sample Output Radius: 20 Area: 1256.64 Circumference: 125.66
- In previous chapters, you have created programs for the Greenville Idol competition. Now create a Contestant class with the following characteristics: The Contestant class contains public static arrays that hold talent codes and descriptions. Recall that the talent categories are Singing Dancing, Musical instrument, and Other. The class contains an auto-implemented property that holds a contestants name. The class contains fields for a talent code and description. The set accessor for the code assigns a code only if it is valid. Otherwise, it assigns I for Invalid. The talent description is a read-only property that is assigned a value when the code is set. Modify the GreenvilleRevenue program so that it uses the Contestant class and performs the following tasks: The program prompts the user for the number of contestants in this years competition; the number must be between 0 and 30. The program continues to prompt the user until a valid value is entered. The expected revenue is calculated and displayed. The revenue is $25 per contestant. The program prompts the user for names and talent codes for each contestant entered. Along with the prompt for a talent code, display a list of the valid categories. After data entry is complete, the program displays the valid talent categories and then continuously prompts the user for talent codes and displays the names of all contestants in the category. Appropriate messages are displayed if the entered code is not a character or a valid code.You are given a Restaurant class below, which represents restaurant information scraped from online reviews website. public class Restaurant { private String name; //name of the restaurant private String address; //restaurant's address private int rating; //average rating of all reviews (1-5) ... // constructors, getters, setters, toString() are already defined Assume 100 Restaurant objects are stored inside the array. Using the array: Calculate and print the average rating of all restaurants.java
- Rainfall Type Create a RainFall class that keeps the total rainfall in an array of doubles for each of the 12 months. Methods in the programme should return the following values: • the total annual rainfall; • the average monthly rainfall • the wettest month of the year • the month with the least amount of rain Demonstrate the class in its entirety. Validation of Input: Accepting negative amounts for monthly rainfall data is not permitted.Python In this assignment, a game called treasure hunt will be written object oriented.There are 3 types of treasures in the game. Diamond, Emerald and Gold. Diamond is 100 points, Emerald 70 points and Gold is 50 points.There are thieves in the game that will prevent you from hunting for treasure. Encountering a thief they steal some of your treasure. You will randomly generate which thief will steal from which treasure and how much.At the beginning of the game, the player has no treasure. X, Y, Z and H will be randomly identified at the start of the game. Define X Diamonds, a random number between X -> 100-200.Let a random number be defined between Y Emerald Y -> 100-200.Define a random number between Z Gold Z -> 100-200.You will define H thieves. Let it be defined between H -> 5-20. It will collect these randomly selected treasures to the player.For example:1- Diamond2-Emerald3-Diamond4-Gold5-Thief (k = treasure to steal, n = how many pieces he can steal)6-Gold.... In…JavaDriver Program Write a driver program that contains a main method and two other methods. Create an Array of Objects In the main method, create an array of Food that holds at least two foods and at least two vegetables. You can decide what data to use. Method: Print Write a method that prints the text representation of the foods in the array in reverse order (meaning from the end of the array to the beginning). Invoke this method from main. Method: Highest Sugar Food Write a method that takes an array of Food objects and finds the Food that has the most sugar. Note that the method is finding the Food, not the grams of sugar. Hint: in looping to find the food, keep track of both the current highest index and value. Invoke this method from main.
- Shape Classes Design classes Square, RightTriangle , and Triangle that encapsulate three geometric shapes. Each class should implement a method void draw (int x, int y) that “draws" a square, a right triangle, or an equilateral triangle (a triangle with three equal sides), respectively. See Figure 2. The parameters x and y specify the relative position of the figure: y lines down and x spaces acro from the current position of the screen cursor. The instance variables of each class are: int rows , the number of rows that comprise the figure, and char character , the keyboard character used for drawing the figure. Each shape of Figure 2 consists of five rows. The drawing characters are *** for the square, %' for the right triangle, and #' for the equilateral triangle. Shape (abstract) int rows char character Shape() Shape(int x, char c) int get rows() char getCharacter() void setRows(int x) void setCharacter(int x) void draw(int x, int y) (abstract) Square() Square(int x, char ch) void…Cs101: Lab #12 Writing Classes II In this lab you will write three classes: Die, PairofDice, and Player. The Die class mimics the rolling of a die. Specifically, this class will implement the following methods: A default constructor initializing the number of sides of a die to 6. An overloaded constructor that takes an integer number of sides (assume greater than 1). roll which generates and returns a random number between 1 and the number of sides (inclusive). An accessor method to read the value of the face on the die. A tostring method returning the string representation of the face value. The maximum number of sides should be stored as a private constant in the Die class. Also use the Random class for the random number generator. The PairofDice class mimics the rolling of two dice. Specifically, this class will implement the following methods: A default constructor that creates and initializes the number of sides of each die to 6. An overloaded constructor that creates and takes…CLASS AND OBJECT Write a program which calculates:| a. An area of a rectangle (length x width), perimeter of a rectangle 2 x (length + width)
