HELP! INTRO. JAVA METHODS

CODE:

import java.util.Scanner; /** This program demonstrates static methods */ public class Geometry { public static void main(String[] args) { int choice; // The user's choice double value = 0; // The method's return value char letter; // The user's Y or N decision double radius; // The radius of the circle double height; // The height of the triangle double base; // The base of the triangle double side1; // The first side of the triangle double side2; // The second side of the triangle double side3; // The third side of the triangle // Create a scanner object to read from the keyboard Scanner keyboard = new Scanner(System.in); // The do loop allows the menu to be displayed first do { // TASK #1 Call the printMenu method choice = keyboard.nextInt(); switch(choice) { case 1: System.out.print("Enter the radius of " + "the circle: "); radius = keyboard.nextDouble(); // TASK #3 Call the circleArea method and // store the result in the value variable System.out.println("The area of the " + "circle is " + value); break; case 2: System.out.print("Enter the height of " + "the triangle: "); height = keyboard.nextDouble(); System.out.print("Enter the base of " + "the triangle: "); base = keyboard.nextDouble(); // TASK #3 Call the triangleArea method and // store the result in the value variable System.out.println("The area of the " + "triangle is " + value); break; case 3: System.out.print("Enter the radius of " + "the circle: "); radius = keyboard.nextDouble(); // TASK #3 Call the circumference method and // store the result in the value variable System.out.println("The circumference " + "of the circle is " + value); break; case 4: System.out.print("Enter the length of " + "side 1 of the " + "triangle: "); side1 = keyboard.nextDouble(); System.out.print("Enter the length of " + "side 2 of the " + "triangle: "); side2 = keyboard.nextDouble(); System.out.print("Enter the length of " + "side 3 of the " + "triangle: "); side3 = keyboard.nextDouble(); // TASK #3 Call the perimeter method and // store the result in the value variable System.out.println("The perimeter of " + "the triangle is " + value); break; default: System.out.println("You did not enter " + "a valid choice."); } keyboard.nextLine(); // Consume the new line System.out.println("Do you want to exit " + "the program (Y/N)?: "); String answer = keyboard.nextLine(); letter = answer.charAt(0); } while(letter != 'Y' && letter != 'y'); } // TASK #1 Create the printMenu method here // TASK #2 Create the value-returning methods here // TASK #4 Write javadoc comments for each method } 

Introduction Methods are commonly used to break a problem down into small manageable pieces. A large task can be broken down into smaller tasks (methods) that contain the details of how to complete that small task. The larger problem is then solved by implementing the smaller tasks (calling the methods) in the correct order. This also allows for efficiencies, since the method can be called as many times as needed without rewriting the code each time. Finally, we will use documentation comments for each method, and generate HTML documents similar to the Java APIs that we have seen. Task #1 void Methods 1. Copy Geometry.java from Blackboard. This program will compile, but when you run it, it doesn't appear to do anything except wait. That is because it is waiting for user input, but the user doesn't have the menu to choose from yet. We will need to create this. 2. Below the main method, but in the Geometry class, create a static method called printMenu that has no parameter list and does not return a value. It will simply print out instructions for
