Java Assignment: Experiment with naming rules in Java Does the language use static or dynamic scoping? Can scopes nest? Are they open or closed?

Please help me design a Passsenger class in C++. THANK YOU! Develop a high-quality, object-oriented C++ program that performs a simulation using a heap implementation of a priority queue. A simulation creates a model of a real-world situation, allowing us to introduce a variety of conditions and observe their effects. For instance, a flight simulator challenges a pilot to respond to varying conditions and measures how well the pilot responds. Simulation is frequently used to measure current business practices, such as the number of checkout lines in a grocery store or the number of tellers in a bank, so that management can determine the fewest number of employees required to meet customer needs. Airlines have been experimenting with different boarding procedures to shorten the entire boarding time, keep the flights on-time, reduce aisle congestion, and make the experience more pleasant for passengers and crew. A late-departing flight can cause a domino effect: the departure gate is…

QUESTION 18 Java uses a hybrid typing system: One system for primitives but everything else is an object. True False

QUESTION 5 Competition synchronization constructs in Java are provided by the Object class. True False

Question 7 Which of the following statements are TRUE? (Check all that apply) There are exactly two distinct semantics models for formal parameters: in and inout There are two conceptual models of how data transfers take place in parameter transmission: Either an actual value is copied (to the caller, to the called, or both ways) or an access path is transmitted. Some languages such as Python allow subprograms to return more than one value. Contemporary software-engineering principles dictate that access by subprogram code to data outside the subprogram should be maximized In most contemporary languages, parameter communication takes place through the heap

4 Object Oriented Programming Assignment - 11 Write a Java program for the following Class Diagram. Document authors: String date: Date getAuthors: String addAuthoriname):void getDate()date Book -titleString getitiet): String EMail Subject: String -to: Stringl) getSubject) String getToString Instructions: 1. This java program is for an application that stores the author (Writer) data of some books and emails 2. getAuthors() method get the list of authors and store it in a String array. 3. addAuthors() method is used to add an author anytime for book or email. 4. getDate() method get the date of the book or email 5. getTitle() method can be used to get the title of the book 6. getSubject() method is used to get the Subject of the email. 7. getTo() method is used to get the information about the mail to whom it is sent. 8. All get methods need to return the values in the corresponding instance variables. 9. Scanner class can be used to set the data for the variables. The programmer can…

In the class diagram below we have a parking charge class for an object-oriented parking system that is to be designed using java. Briefly explain any implementation decisions and the reasoning behind those without writing the complete code. N.B explain how the implementation will proceed instead of writing code
