Need help with this please Q.1Description (same for next three questions)Your job is to write an instantiable class that represents a parcel of raw land that can be sold by a realestate company. This class should be named Land. It will contain two fields: width and length, measuredIn feet, each of which can accept numbers with decimal points. You may assume that every parcel ofland is rectangular and that width' describes the size of the property along the road and length' is howfar back it goes from the road.The class needs one constructor that sets the values of the two fields.The class needs the following public methods:Getters and setters for all fields.A method called getArea that calculates and returns the area of the parcel of land in squarefeet.Standard methods: tostring, equals, and hashCode where equals and hashCode define anequivalent parcel of land as one with exact same the same dimensions.• Implementation of the Comparable interface.For this question, write a complete UML class diagram for this class. Use a line of minus signs toseparate sections. Don't worry about drawing a box or centering any text. Do include all proper UMLnotation.Q.2Using the same information as in the previous question, create a NetBeans project named Exam2 andcreate the Land class with all the fields, constructors, and methods listed. Copy and paste the code forthat class here. To retain your formatting, change the Canvas editor from Paragraph to Preformatted,switch to HTML mode, and then paste your code between the and tags.Q.3Write a JUnit class that tests the instantiable class. It is your job to determine what makes sense to testand what values to use in order to thoroughly test the class's methods. Copy and paste the entire codehere. To retain your formatting, change the Canvas editor from Paragraph to Preformatted, switch toHTML mode, and then paste your code between the and tags.

Answer: our guidelines is answer first three question from the first question. So I have given…

Description (same for next three questions) Your job is to write an instantiable class that represents a parcel of raw land that can be sold by a real estate company. This class should be named Land. It will contain two fields: width and length, measured In feet, each of which can accept numbers with decimal points. You may assume that every parcel of land is rectangular and that 'width' describes the size of the property along the road and Tength' is how far back it goes from the road. The class needs one constructor that sets the values of the two fields. The class needs the following public methods: Getters and setters for all fields. A method called getArea that calculates and returns the area of the parcel of land in square feet. Standard methods: toString, equals, and hashCode where equals and hashCode define an equivalent parcel of land as one with exact same the same dimensions

C++ 2. Define a new "Degree" class that contains a year (integer), a subject (string), and a person’s name (string). For example, a degree can have "John Smith", 2020, and "Computer Science" It should have at least the following methods:- toString method must return all the degree information: year, subject, and person’s name.Here is an example of the formatted degree string:NAME(John Smith) SUBJECT(Computer Science) YEAR(2020) - hasTheSameDegree method compares 2 degrees and returns true if both have the same year and the same subject. Otherwise, it returns false. - isLater method that compares 2 degrees and returns true if the current degree has the year later than the 2nd degree and false otherwise. Important notes: - You can add as many other methods as you need. But this class should not provide the default constructor. - Show how this class and its methods are being used, called, and produce the correct results.

7.21 LAB: Random values use Java. In the file RandomNumbers.java, write a class called RandomNumbers that has three integer instance variables: var1, var2, and var3. Write getter method for each variable: getVar1(), getVar2() and getVar3(). Then write the following 2 instance methods: setRandomValues( ) - accepts a low and high integer values as parameters, and sets var1, var2, and var3 to random numbers (generated using the Random class) within the range of the low and high input values (inclusive). getRandomValues( ) - prints out the 3 random numbers in the format: "Random values: var1 var2 var3" Ex: If the input is: 15 20 the output may be: Random values: 17 15 19 where 17, 15, 19 can be any random numbers within 15 and 20 (inclusive). Note: When submitted, your program will be tested against different input range to verify if the three randomly generated values are within range. import java.util.Scanner; public class LabProgram {// main method used to test your codepublic…
