Java 2. Every circle has a center and a radius.- Given the radius, we can determine the circle's area and circumference.- Given the center, we can determine its position ini the x-y plane. Thecenter of a circle is a póint in the x-y plane.- Design the class Circle that can store the radius and center of thecircle. Since the center is a point in the x-y plane , we can use the Pointclass that we already designed in #1, we must derive the class Circle fromthe class Point. We should be able to perform the usual operations on acircle, such as setting the radius, printing the radius, calculating and printingthe area and circumference, and carrying out the usual operations on thecenter.The class Circle should contain the folowing methods and data member:12. protected member radius13. default constructor14. constructor with parameters15. setCircle(x)16. getRadius(')17. setRadius(x )18. toString( )19. equals(x)20. makeCopy(x)21. getCopy(')22. printCircle( )23. area( ) -x • r224. circumference( ) - 2 • z • radius The output should show the following:Initialize myCircle to (5.00, 4.00, 7.23)Initialize yourCircle to (Õ.00, 0.00,0.00)Set yourCircle to (5.00, 45.00, 82.20)Determine the area of yourCircle: ???Determine the circumference of yourCircle: ???- Determine if the 2 circles are equal or not- Enter the center as (6.50, 8.75)Enter the radius as 13.0Set myCircle with (6.50, 8.75, 13.00)Copy myCircle into yourCircle and then print yourCircle.

Create a Right Triangle class that has two sides. Name your class rightTraingle. Code getter and setters for the base and the height. (Remember class variables are private.) The class should include a two-argument constructor that allows the program to set the base and height. The constructor should verify that all the dimensions are greater than 0. before assigning the values to the private data members. If a side is not greater than zero, set the value to -1. The class also should include two value-returning methods. One value-returning method should calculate the area of a triangle, and the other should calculate the perimeter of a triangle. If either side is -1, these functions return a -1. The formula for calculating the area of a triangle is 1/2 * b*h, where b is the base and h is the height. The formula for calculating the perimeter of a triangle is b+h+sqrt (b*b+h*h). Be sure to include a default constructor that initializes the variables of the base, height to -1. To test…

Answer the following and code in Java Thank you
Fibonacci A fibonacci sequence is a series of numbers in which each number is the sum of the two preceding numbers. For example: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and so on… For this, you will implement a class that takes a positive integer (n) and returns the number in the nth position in the sequence. Examples When n is 1, the returned value will be 0. When n is 4, the returned value will be 2. When n is 9, the returned value will be 21. come up with the formula and base cases Implementation Create a class Fibonacci with a public static method getValue. Create a Main class to test and run your Fibonacci class.

Implement the above system using inheritance in the best possible way. Keep every object size as small as possible. Implement all methods (setter/getter/constructors and destructors) Note that the region area is 0 while the city is len*width and the country is the sum of their cities. Create array of countries called Arab of 22 countries. Write a function fill that fills the array Arab Write a method that finds the city that has the max area in a country Write a method that sorts the cities in a country from the largest to the smallest area Write a function that returns array of countries of the same area of Arab Write a function that compares between two countries. It returns true if country1 area greater than country2 area. Write a function to move a city from one country to another.

Ro-Sham-Bo. Believe it or not, the classic game of Rock-PaperScissors has many other names. One of them is Ro-Sham-Bo. For this assignment, “Ro” will represent “Rock”, “Sham” will represent Paper, and “Bo” will represent Scissors. You will create a RoshamboPlayer class. It will have three attributes: PlayerName: String RoLimit: int ShamBoLimit: int It will also have an overloaded constructor that sets those three values. It will have two functions: playRound that takes in a string and returns a boolean value, and getName that takes in nothing and returns the PlayerName string. In your driver class for this assignment, you will create two RoshamboPlayer objects with the following values: p1: RoLimit == 30, ShamBoLimit == 60 p2: RoLimit = 40, ShamBoLimit = 85 You may name them whatever you like. You will prompt the user to choose one of these two to play against. Then you will create a loop that prompt the user to either play a round of Roshambo, or quit the game. If the user chooses…
