a.

Program Plan Intro

Explanation of “ElevatorSimulation2.java”:

Refer the “ElevatorSimulation2.java” in textbook that describes about the elevator simulation program. In this program,

• Read the floor value from the user.
• Check whether the given input is integer value.
  • If the floor value entered by the user is equal to 13 then it will raise the error that “there is no thirteenth floor”.
  • If the floor value entered by the user is less than 0 or greater than 20 then it will throw the error that “the floor value must be between 1 and 20”.
  • If the floor value is greater than 13 then it subtracts the value of “1” from the given floor value and it displays the message to the user.
• If not an integer value, then it throws an error
