Can you create an object of IntegerProperty using new IntegerProperty (3)? If not, what is the correct way to create it? What will be the output if line 8 is replaced by d1.bind (d2.multiply (2)) in Listing 14.6? What will be the output if line 8 is replaced by d1.bind (d2.add (2)) in Listing 14.6?

- 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.

A man approached and said he could not believe that electric cars existed. He intends to prove her wrong. You go to the scene and check out the first car. You discard the first two items when they are not electric, although there may be gas cars going on down the line that proved your point and in this case, they can restore the list of remaining cars.

- Please help with the rest of the subparts of the code! The first three were very good!arrow_forwardc) This question requires you to write the code for a Java servlet called RespondServlet. This servlet will receive a POST request with the URL parameters: name="Oliver Twist"&type="student"&year="3" When accessed, the servlet should reply with an unformatted document (i.e., in plain text): that has the value of the three parameters contained in the document, such that they will be printed in the browser screen; ● that displays the message "Some data is missing!" if the value of either the name or type parameters is missing, to ensure your servlet code is robust (i.e., it can cope with invalid inputs). Note: Your answer must only make use of programming concepts that were covered in the module. ●arrow_forwardHello! I need help in making a basic C# Minesweeper Console game. The requirements would be that: the board is covered at the start of the game (would be great if "■" would be used), Random rand = new Random(); for distributing the mines across the gameboard, the user can flag a possible mine, putting down an 'F', user can uncover squares, using Console.ReadLine, writing the column/row number, there is a Console.WriteLine for losing/winning, Console.ReadLine("Y/N?"); for restarting the game after losing. I would really need to see the full code as I want to learn from it, try to add to it etc.arrow_forward
- I need the source code for this question 4 in Java. Please provide an explanation for the methods provided. Client Class:The client program should read the input data from the user (or the method with hardcoded inputs)and use the Change class to store the data entered. This data should be stored in a Change classobject. You will need a data structure to store the Change class objects according to the number ofpersons entered. Thus, you are to utilize an array of Change objects. Do not use ArrayList for thisassignment It should be noted that it is possible to have the same name entered numerous times, but the coinvalues for such repetitions could be different. When the name is the same, it would mean the sameindividual, and your program should add up the coin amounts to obtain a total amount for thatindividual; this should be performed before computing the change to be given. Note that in thisscenario, the total amount for an individual may end up being over 100, 200, 300, or more cents…arrow_forwardI already have the code for the assignment below, but the code has an error in the driver class.
