- Design a LandTract class that has two fields (i.e. instance variables): one for the tract’s length(a double), and one for the width (a double). The class should have: a constructor that accepts arguments for the two fields a method that returns the tract’s area(i.e. length * width) an equals method that accepts a LandTract object as an argument. If the argument object holds the same data (i.e. length and width) as the calling object, this method should return true. Otherwise, it should return false. a toString method (that returns a String representation of the tract’s length, width, and area). Demonstrate the class in a program by creating an array of three LandTract objects initialized with user input. Then, print the info of the LandTract objects stored in the array by invoking the toString method (implicitly or explicity). Also, use the equals method to compare at least two LandTract objects and print wether they are of equal size or not. Sample Output:…1. Part 1: A point in the x-y plane is represented by its x-coordinate and y-coordinate. Design the class Point that can store and process a point in the x-y plane. Your class should contains the following methods. Default constructor without parameters that initializes the private data member to the suitable values Constructor with parameters sets the values of the instance variables to the values of the parameter. Accessor methods that return the values of the x-axis and y-axis. setPoint method which set the values of x-axis and y-axis makeCopy method that make a copy of a received object of type Point. getCopy method that returns a copy of the current object toString method that returns the object string isEqual that returns true if the current object is equal to the received object of type point distance, which receives two objects of type Point and returns the distancePlease help with the following: C# .NET change the main class so that the user is the one that as to put the name a driver class that prompts for the person’s data input, instantiates an object of class HealtProfile and displays the patient’s information from that object by calling the DisplayHealthRecord, method.

- Temp Class - Create Temp class whos job is to hold a temp in degrees F and gives methods to get the temp in F, Celsius, and Kelvin. The class should follow the instance variable (field): ftemp (double type that holds F temp)Follow these methods with the class.. Constructor --Will accept Fahrenheit temperature as a double to store it in the ftemp field. setFahrenheit - The setFahrenheit method accepts a Ftemperature as a doubleto stores it in the ftemp field. getFahrenheit - Returns the value of the ftemp field, as a Fahrenheit temperature (no conversion required). getCelsius - Returns the value of the ftemp field converted to Celsius. [C e l s i u s = ( 5.0 / 9.0 ) × ( F a h r e n h e i t − 32 )] getKelvin - Returns the value of the ftemp field converted to Kelvin.
