In java language Class Design – Date V0.0 & V1.0 Create a new project for this lab and create a new class inside called Date. If you created a Date class last week, you may use it as a base. What does it mean to be a Date? What data items (called “state”) do you need to keep track of? Alternatively, what does a date have? (“has a” == composition) What can a Date do? What are the actions and verbs that can be applied to a date? Come up with one or two. These become the class’s methods. Try adding 3 data items to your Date to manage the month, day and year. Should these be local variables? Class-level (or instance) variables? Now let’s build a method to set the date This function should take 3 integers as input and assign these to your instance variables declared in the previous step. public void setDate(int m, int d, int y) { And, let’s build a method to report the date This function takes no input and uses the console to output the Date in the format…

Create a Python project fly_drone. Add a Python file drone.py to this project. Define a class Drone in this file. This class has the following five methods: __init__ : Create two instance variables to store the speed and the height of the drone. Initialize them to 0.0. This method has no parameters other than self and no return value. accelerate : Increase the speed of the drone by 10. This method has no parameters other than selfand no return value. decelerate : Decrease the speed of the drone by 10. The new speed cannot be negative. This method has no parameters other than self and no return value. ascend : Increase the height of the drone by 10. This method has no parameters other than self and no return value. descend : Decrease the height of the drone by 10. The new height cannot be negative. This method has no parameters other than self and no return value. The following class diagram shows the design of this class: Drone +speed: Float +height: Float…

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.

I've posted this question several times. T-T) huhu... i just need the source code in java language. thank you. don't answer #6 i already got it from my previous post. 1: Create a new class with attributes name and address. Both data type will be String. Create a constructor and assign the parameters to the attributes. Now override the toString() method. Is this possible? 2: Create a class with the main method and create an instance of the class that you created in Test Stem 1. What method can you call to get the hashCode of your class? 3: What is the return type of the hash code ? 4: Create an instance of the string in your test class and assign a value. Which of the following operators can be used in conjunction with a string object? + - & . += 5: Supposed that we have a string with a value “This is my string.”. Which method can be used to extract a specific word from the given string? 6: Supposed that we have a string with a value “This is my string.”. Which…
Description what the JAVA should execute: Create a new project called Family. Add a person class with name, birthDate, and sex private instance variables. Create the public getter and setter methods for each. Create an overloaded constructor that initializes all of the instance variables. Create the default constructor. Override the toString() method to show the Person's info. Create the Person in the main method, and display that person's info. Now add a new instance variable to the Person class of type Person with the identifier spouse. Spouse should be private with setter and getter methods. If you try to instantiate spouse in the contructor, you will get a stack overflow error. Each Person, creates a Person, creates a Person, and so on forever. Try that to see the error and then remove the code from the constructor. Error melt: One or more project compiled with errors JAVA 1: package Family; public class Family { private static String steveStudent;private static Person…
Objective: Write a class that will test dates and times inputted by the user and determine whether or not it is valid. This will focus on the usages of methods to organize code. First download the driver and put it in your project DO NOT ALTER THE DRIVER! Use this to run your project The driver : public class DateAndTimeDriver { public static void main(String[] args) { // TODO Auto-generated method stub DateAndTimeTester dtTester = new DateAndTimeTester(); dtTester.run(); } } Write a class file called DateAndTimeTester This DOES NOT have a main method Create the following methods run: This method returns nothing and takes no parameters. This is called by the driver and should handle all of the input from the Scanner and dialog for the user. isValid: returns true or false if a given String has the correct date and time. The String parameter should be formatted “MM/DD hh:mm” This method should call the methods isValidDate and isValidTime to determine this. isValidDate: returns…
