1 of 3 Lab 04_SPRING_2021-Revised.pdf 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 the file Geometry.java (Code Listing 5.1) from the Student Files or as directed by your instructor. 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, 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 the user with a menu of options for the user to choose from. The menu should appear to the user as: 8:51 PM Sun 14 Feb @ 24% Lab 04_SPRING_2021-Revised.pdf *** University of Jeddah 2 of 3 2. This is a geometry calculator Choose what you would like to calculate 1. Find the area of a circle Find the area of a rectangle 3. Find the area of a triangle Find the circumference of a circle 5. Find the perimeter of a rectangle. Find the perimeter of a triangle Enter the number of your choice: 3. Add a line in the main method that calls the printMenu method as indicated by the comments. 4. Compile, debug, and run. You should be able to choose any option, but you will always get O for the answer. We will fix this in the next task. Task #2 Value-Returning Methods 1. Write a static method called circleArea that takes in the radius of the circle and returns the area using the formula Arar? 2. Write a static method called rectangleArea that takes in the length and width of the rectangle and returns the area using the formula Alw
