Using Java an elevator simulator that uses polymorphism and object-oriented programming tosimulate the movement of elevators in a building with multiple types of passengers and elevators.The system has 8 elevators, each of which can be one of 4 types of elevators, with a certainpercentage of requests for each type. Similarly, each passenger can be one of 4 types, with adifferent percentage of requests for each type. Passenger Types:There are 4 types of passengers in the system:Standard: This is the most common type of passenger and has a request percentage of 70%.Standard passengers have no special requirements.VIP: This type of passenger has a request percentage of 10%. VIP passengers are given priorityand are more likely to be picked up by express elevators.Freight: This type of passenger has a request percentage of 15%. Freight passengers have largeitems that need to be transported and are more likely to be picked up by freight elevators.Glass: This type of passenger has a request…

Write a program in Java to perform the followings, (i) Design one parent and two child classes. Names of parent and child classes along with the names of their variables and methods should be taken from real-life by yourself. Parent class should have at least two variables, one parameterized constructor and one method to perform any meaningful operation/calculation with the variables. Child classes should have at least one additional variable declared within (ii) (iii) them and one parameterized constructor, and a toString method. (iv) Design another class and a main method inside it. Declare at least one object of each of the two child classes using parameterized constructor. Call the method of the parent class with these objects to perform the particular operation/calculation on these objects and show the result. Display values of all the variables of these objects using toString. Write the Java program using Eclipse IDE, copy and paste the code along with the output in a word file.…
