I am a freshman and new to Java. I am making an Elevator Simulation as my project but don't know how it works. I tried to upload the code I had but I was having format problem. So on the bottom, I wrote some classes and wrote what I am planning to write inside. It would be helpful if any of you can tell me what I need to improve or add.
Instructions: The goal is to create an elevator simulation using object-oriented programming and polymorphism. The simulation involves 8 elevators, each of which can be one of 4 types with different percentages of requests, and 4 types of passengers with different percentages of requests. The elevator types include Standard, Express, Freight, and Glass elevators, while the passenger types include Standard, VIP, Freight, and Glass passengers. The simulation starts with a specified number of passengers added to different floors of the building, and during the simulation, the elevators will move up and down the building, picking up and dropping off…
The sections that immediately follow include the definitions of the classes MonthCalender and DateTimerPicker, respectively.
What is meant by Regular Expression? Why we used it? What is the difference between a regular expression and a descriptive method? Kindly give some examples

- The Main class, ITrip interface, and SimpleTrip class have been provided for you. The remaining classes you will have to complete on your own. The Builder is responsible for building your trip by creating several ComplexTrip and SimpleTrip objects and connecting them. Your trip should start at Home and then visit North Adams and Pittsfield. While in North Adams you will visit MASSMoCA, with a stop at the Lewitt Exhibit and the Cafe, and then you will check out MCLA. While in Pittsfield you will visit the Science Museum and then catch a Baseball Game. When your program is working correctly, your program should produce the following output: Visiting Home Visiting North Adams Visiting MASSMoCA Visiting Lewitt Exhibit Visiting Cafe Visiting MCLA Visiting Pittsfield Visiting Science Museum Visiting Baseball Game import java.util.*;import java.io.*; public class Main{ public static void main (String[] args) throws Exception { ITrip e = (Builder.getInstance()).createTrip();…arrow_forwardFind examples of javadoc key symbols in the source code of the TechSupport project.
