- Java - Access Specifiers Create a class named Circle that has attributes radius, area, and circumference and make the attributes private. Make a public method that sets the radius and a method that prints all attributes. Ask the user input for radius. Note: Use the PI from the math functions Inputs A line containing an integer 10 Sample Output Radius: 20 Area: 1256.64 Circumference: 125.66Kingdom of Trolls is celebrating their Kingdom Day and one of the activities that is taking place is a game where a player rolls a magic ball down the hill on a path with spikes. As the ball rolls down, it strikes a spike and bursts open to release a number of smaller balls (in our simulated game, the number of smaller balls is a randomly generated integer between 2 and 6, inclusive). As the smaller balls further roll down, when one strikes a spike, that ball and all its sibling balls burst and each generates another set of smaller balls (using the same random number already generated for the first roll). The balls keep rolling downhill and striking spikes and bursting into smaller balls until a golden ball is released by one of the bursts. At this time, the game is over and the player is told how many balls were generated during the last burst (including the golden ball). The game is played by two players at a time and the player who had the lowest number of balls generated on the…Implement the following classes: Polygon numSide: int /* constructor */ /* accessor-mutator */ + area (): double + perimeter (): double Triangle sideA: double sideB: double sidec: double /* constructor */ /* accessor-mutator */ + area () : double + perimeter (): double Create an object for Triangle class and invoke area and perimeter method.

- 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.A constructor that creates a regular polygon with the specified number of sides, length of side, and x-and y-coordinates. • The method getPerimeter() that returns the perimeter of the polygon. The formula for computing the perimeter of a regular polygon is: p=s.n • The method getArea() that returns the area of the polygon. The formula for computing the area of a regular polygon is n x s? Area = 4 X tan n Write a test program that creates three RegularPolygon objects, using the no-arg constructor, using RegularPolygon(6, 4), and using RegularPolygon(10, 4, 5.6, 7.8).
