Question

This is an intro to java question. Please post with pseudocode and java code.

Problem should be completed using repetition statements like while and selection statements.

Geometry (10 points) Make API (API design) Java is an extensible language, which means you can expand the programming language with new functionality by adding new classes. You are tasked to implement a Geometry class for Java that includes the following API (Application Programming Interface): Geometry Method API: Modifier and Type Method and Description static double getAreaRectangle(double width, double length) Returns the area of a rectangle, area = length * width static double getAreaCircle(double radius) Returns the area of a circle, area = ?(radius 2 ) static double getAreaTriangle(double base, double height) Returns the area of a triangle, area = ½(base * height) static double getPerimeterRectangle(double width, double length) Returns the perimeter of a Rectangle, perimeter = 2(length + width) static double getPerimeterCircle(double radius) Returns the perimeter of a Circle, perimeter = 2?(radius) static double getPerimeterTriangle(double side1, double side2, double side3) Returns the perimeter of a triangle, perimeter = s1 + s2 + s3 Facts ● Java Math class contains an approximation for PI, i.e. Math.PI ● Your Geometry class implementation should not have a main method. ● NO Scanner for input & NO System.out for output! Input The Geometry class will be accessed by an external Java Application within Autolab. This Java app will send data in as arguments into each of the methods parameters. Output The Geometry class should return the correct data calculations back to the invoking client code

Answer 1

CODE

class Geometry {

static double getAreaRectangle(double width, double length) {

return width * length;

}

static double getAreaCircle(double radius) {

return Math.PI * radius * radius;

}

static double getAreaTriangle(double base, double height) {

return 0.5 * base * height;

}

static double getPerimeterRectangle(double width, double length) {

return 2 * (width + length);

}

static double getPerimeterCircle(double radius) {

return 2 * Math.PI * radius;

}

static double getPerimeterTriangle(double side1, double side2, double side3) {

return (side1 + side2 + side3);

}

}

public class Main {

public static void main(String[] args) {

System.out.println(Geometry.getAreaRectangle(1,1));

System.out.println(Geometry.getAreaCircle(1));

System.out.println(Geometry.getAreaTriangle(1,1));

System.out.println(Geometry.getPerimeterRectangle(1,1));

System.out.println(Geometry.getPerimeterCircle(1));

System.out.println(Geometry.getPerimeterTriangle(1,1,1));

}

}
