Write Java Code for the following case scenarios:

Consider the following class declaration:

public class Circle

private double radius;

public Circle $($double r$)$

$\{$

radius $=$ r;

$\}$

public double getArea$()$

$\{$

return Math.PI $*$ radius $*$ radius;

$\}$

public double getRadius$()$

$\{$

return radius;

$\}$

$\}$

Write a toString method for this class. The method should return a string containing the radius and area of the circle.

Write an equals method for this class. The method should accept a Circle object as an argument. It should return true if the argument object contains the same data as the calling object, or false otherwise.

Write a greaterThan method for this class. The method should accept a Circle object as an argument. It should return true if the argument object has an area that is greater than the area of the calling object, or false otherwise.

Make a Land Tract class that has two fields: one for the tracts length and one for the width. The class should have a method that returns the tracts area, as well as the equals method and a toString method. Demonstrate the class in a program that asks the user to enter the dimensions for two tracts of land. The program should display the area of each tract of land and indicate whether the tracts are of equal size.

Convert the following UML diagram into the Java code. Write constructor for the given class. Create an instance of the class in a main method using a Display class."
