Help, I making a elevator simulator, I need help in writing code in the Elevator class and it's polymorphism class. I am not sure what to do next. Any help is appreciated.
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 priority and are more likely to be picked up by express elevators.Freight: This type of passenger has a request percentage of 15%. Freight passengers have large items that need to be transported and are more likely to be picked up by freight elevators.Glass: This type of passenger has a request percentage of 5%. Glass passengers have fragile items that need to be transported and are more likely to be picked up by glass elevators.

Can you implement the Derived Class Parameterized constructor? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first.
Implement the constructor Dell(String name) of the Derived Class Dell which takes a string, name. We have already implemented the Base Class Laptop with the member function getName() and a parameterized constructor.
Input#
Laptop name is being passed through the parameterized constructor.
Output#
getName() method is returing Laptop name.
Sample Input#
Dell dell = new Dell("Dell Inspiron");
Sample Output# "Dell Inspiron"

You must create (in C++) a Checkpoint class with a hidden attributes (Authorized, Guest, Unauthorized), two constructors (a default that sets all access levels to false and an overloaded that sets Authorized and Unauthorized to false and Guest to true for testing purposes) and a method that changes the access level to the next in the sequence (Authorized – Guest – Unauthorized).arrow_forwardUse NetBeans Note for all the above User-Defined Classes: • Provide appropriate validation code so the right values get populated in the instance variables.

Write a Java application (Client) program with a static method called generateEmployees( ) that returns a random list of 10 different types of Employee objects. You would use an ArrayList to store the employee objects that will be returned. Use a for loop to populate randomly different types of employee objects with some random data. You could possibly think of a range of values like 1 – 4. If random value is 1, create a HourlyEmployee object with some randomly generated data, if 2, a SalariedEmployee object with some random data and so on. I would leave it to your ingenuity to generate and populate these different Employee objects with other data like name etc. As these objects are generated, add them to your data structure (array or ArrayList that you are using).

Write a recursive method that returns the number of places where the two passwords have different characters. The passwords can have different lengths. Write another, nonrecursive method returning whether the two passwords are sufficiently different. The method takes an int parameter indicating the minimum number of differences that qualify the passwords as being sufficiently different.

It should be the only function which dynamically allocates a char array to hold the name. setName(char *): this is a public member function which changes the name of the rectangle to a new name. It does not dynamically allocate memory, it only changes name. Demonstrate your class works…arrow_forward
