- Create a class with a method. The method has to decide whether a given year is a leap year or not. Note- A year is a leap year if: • It has an extra day i.e. 366 instead of 365. It occurs in every 4 year e.g. 2008, 2012 are leap years. For every 100 years a special rule applies-1900 is not a leap year but 2000 is a leap year. In those cases, we need to check whether it is divisible by 400 or not. > > ClassAssignmentEx2 ©LeapYearDecider javaclassnotes.assignments javaclassnotes.assignments ClassAssignmentEx2() LeapYearDecider() main(String):void A isLeapYear(int):booleanHere is _The output of first method should be that they are not equal. And the output of the second method should be that they are equal. Partial code is given below to help you complete this question. You can ignore this entirely and write your...canMove(int x, int y, int destX, int destY, Side s): This method returns true if the player of color s can move the piece at coordinates (x,y) can move to coordinates (destX, destY) on the board in its current state. This means that here you do need to consider this piece’s interaction with other pieces on the board. Conditions for this method to return false are given in the code. public boolean canMove(int x, int y, int destX, int destY, Side s){ /* TODO write a method that checks if a piece at coordinates x,y can move to coordinates destX,destY Conditions for false: - Origin or destination coordinates are outside the board - Piece at origin is null - If source and destination coordinates are the same - Piece at origin is not of the same side as s - You can check this using piece.getSide() - Piece cannot move to the destination by piece movement rules - You should check this using Piece.canMove(destX,…
- Add the following accessor methods to your Rectangle class:public boolean contains(int x, int y)public boolean contains(Point p)Returns whether the given Point or coordinates lie inside the bounds of this Rectangle .Design an application that does the following: A Solid can be a FlatSurfaceSolid or a CurvedSurfaceSolid. Every solid will have a volume. The method volume will be polymorphic. A solid has faces, vertices and edges. A flat-surface solid also has a variable called side which represents the length of the side. A curved-surface solid also has a radius. A Cube is a FlatSurfaceSolid. A cube has 6 faces, 8 vertices and 12 edges. It will have a side. A Sphere is a CurvedSurfaceSolid. It has 1 face, 0 vertices and 0 edges. It will have a radius. Create an ArrayList of solids (driver file named YourLastNameCISC231Q1.java). The arraylist will have 4 elements – 2 cubes (one with side length 3 and another will side length 4) and 2 spheres (one with radius 3 and another with radius 4). Create a driver class to instantiate an array of solids and display the details of each solid along with the volume of each solid.Complete the Team class implementation. For the instance method get_win_percentage(), the formula is:team_wins / (team_wins + team_losses) Note: Use floating-point division. Ex: If the input is: Ravens 13 3 where Ravens is the team's name, 13 is the number of team wins, and 3 is the number of team losses, the output is: Congratulations, Team Ravens has a winning average! If the input is Angels 80 82, the output is: Team Angels has a losing average. coede used: class Team: def __init__(self): self.team_name = 'none' self.team_wins = 0 self.team_losses = 0 # TODO: Define get_win_percentage() if __name__ == "__main__": team = Team() team_name = input() team_wins = int(input()) team_losses = int(input()) team.team_name = team_name team.team_wins = team_wins team.team_losses = team_losses if team.get_win_percentage() >= 0.5: print('Congratulations, Team', team.team_name,'has a winning average!') else:…

A method in the Piece class returns if the piece may travel to position (x, y). Describe how you would put this method to the test.You are given an interface AdvancedArithmetic which contains a method int divisor_sum(int n). You need to write a class called MyCalculator which implements the given interface. The divisor_sum method takes an integer as input and return the sum of all its divisors. For example divisors of 6 are 1, 2, 3 and 6, so divisor_sum should return 12
- There are several techniques for implementingthe sqrt method in the Math class. One such technique is known as theBabylonian method. It approximates the square root of a number, n, by repeatedlyperforming the calculation using the following formula:nextGuess = (lastGuess + n / lastGuess) / 2When nextGuess and lastGuess are almost identical, nextGuess is theapproximated square root. The initial guess can be any positive value (e.g., 1).This value will be the starting value for lastGuess. If the difference betweennextGuess and lastGuess is less than a very small number, such as 0.0001,you can claim that nextGuess is the approximated square root of n. If not, nextGuessbecomes lastGuess and the approximation process continues. Implementthe following method that returns the square root of n:public static double sqrt(long n)Using Java Programing, write a RainFall class that stores the total rainfall for each of 12 months into an array of doubles. The program should have methods that return the following: the total rainfall for the year the average monthly rainfall the month with the most rain, and the month with the least rain. Demonstrate the class in a complete program. Input Validation: Do not accept negative numbers for monthly rainfall figures.java program Write the equals method for Circle2 which returns true when the radius and the color are the same as the parameter’s radius and color. The TestCircle2, Circle2 and GeometricObject2 classes are given as follows. public class TestCircle2 { public static void main(String[] args) { Circle2 c1 = new Circle2(2.3, "red"); Circle2 c2 = new Circle2(5.6, "white"); Circle2 c3 = new Circle2(2.3, "red"); System.out.println("c1 equals c2: " + c1.equals(c2)); System.out.println("c1 equals c3: " + c1.equals(c3)); System.out.println("c2 equals c3: " + c2.equals(c3)); } } class Circle2 extends GeometricObject2 { private double radius; public Circle2() { } public Circle2(double radius) { this.radius = radius; } public Circle2(double radius, String color) { this.radius = radius; setColor(color); } /** * Return radius */ public double getRadius()…
