Java Programming

This program will allow the user to select one of five geometric solid calculators from a menu. The menu will then call one of five methods to perform the volume calculation, and then the volume will be returned to the main ( ) method for display. A sixth option lets the user quit the app without doing anything. Method main () Create yourmain () method so that it prompts the user with the menu below. Store the menu choice to an appropriate input-capture variable. Then, use an if-else if or switch statement to evaluate the variable and call the appropriate void ( ) method, quit, or display an error message: Type the number to select a geometric solid calculator: Calculate the volume of a sphere Calculate the volume of a cone Calculate the volume of a rectangular solid Calculate the volume of a cylinder Calculate the volume of a pyramid Do nothing (quit) Specifics: Create one input-capture variable for the menu choice. The method calls must occur within the if /else if or switch block. Each shape menu item needs to call a separate void() method that will do four things: prompt the user for the proper inputs; perform the volume calculation; display the result; and return control to the calling method, main () . If the user types 1 through 5, then call the associated method In each of your void () methods, display the output to two decimal places, as below. Follow this verbiage and format for your output: Volume of the rectangular solid is 35.15 cubic inches If the user types 6 to quit, simply display the word goodbye and end the program: Goodbye If the user types in any other number besides 1 to 6, display an error message and end the program Error: Your options are 1 to 6. Individual Methods Each method must calculate the volume of one of the five solids so you will need five separate methods.
