Lab_02.2B For the following exercises, use return methods with parameters. Create a new.repl doc called APLab_02.2B, and the following files.

Exercise_01: Rectangle

Create a new file called Rectangle.java, and add the following.

maino

Declare 2 variables - length, and width for the length and width of your rectangle, and set their values to user inputs. Print the perimeter, which is returned from

calcPerim calcPerim

Take 2 parameters that accept the local length and width values from main(. Calculate and return the perimeter.

Exercise_02: Average

Create a new file called Average.java, and add the following.

main

Declare 3 variables - numi, num2, and num3, and set their values to user inputs. Print the average, which is returned from

calcAvgo. calcAvg

Take 3 parameters that accept the values from num1, num2, and num3 that are local to main(). Calculate and return the average.

Exercise_03: Cube

Create a new file called Cube.java, and add the following.

main

Declare a variable side for the length of the sides of your cube. Set the value of side to a user input. Print the surface area of a cube, with a length of side. Print the surface area of your cube which is returned from

calcSurf| calcSurfa

Take 1 parameter, which will accept the value of your local variable for side length from main(). Calculate and return the surface area.

Exercise 04: Circle

Create a new file called Circle.java, and add the following.

Main

Declare a variabler for the radius of your circle, and set the value ofr to a user input. Print the area of your circle, which is returned from

calcAreal calcAreal

Take 1 parameter, which will accept the value of your local variable for radius from main. Calculate and return the area of your circle.
