- In JavaScript, a constructor needs to link an object to other functions so that methods are performed only on the object that calls them. (a) True (b)FalseWrite code in java object oriented programming. You are required to create a simple command line application that allows users to do two basic things, (1) create an email comprising of properties, to, from, subject and message and (2) to create a book chapter that has the properties of chapter title, chapter number and chapter contents. When the program begins its execution, your program should first ask the user for the sender and receiver for the email, its subject and lastly its message; it should then display the entire email in a well-structured format. Second, the program should ask the user for the book chapter name, its number and finally the contents that go in the chapter. At the end, display the book chapter along with all the properties.object oriented programming using c++ class decleration: class MyPhoneBook{ string* names; string* phones; int phoneBookSize; public: MyPhoneBook(int); //Takes size MyPhoneBook(const MyPhoneBook&); //Copy Constructor bool addEntry(string ,string); bool displayEntryAtIndex(int); void displayEntryAtIndices(int*); void displayAll(); int* findByName(string); int* findByPhone(string); bool updateNameAt(string, int); bool updatePhoneAt(string, int); ~MyPhoneBook();};

Furthermore, each flight has a unique flight ID and the information whether the flight is direct or not.Create a C++ class to model a flight. (Note: Make separate classes for Date and Time and use composition).add two integer data members to the Flight class, one to store the total number of seats in the flight and the other to store the number of seats that have been reserved. Provide all standard functions in each of the Date, Time and Flight classes (Constructors, set/get methods and display methods etc.).Add a member function delayFlight(int) in the Flight class to delay the flight by the number of minutes pass as input to this function.

- In Java Create a Cat object passing in the gender and name to the constructor: uses overload Cat constructorObject Oriented Programming in JAVA You are part of a team writing classes for the different game objects in a video game. You need to write classes for the two human objects warrior and politician. A warrior has the attributes name (of type String) and speed (of type int). Speed is a measure of how fast the warrior can run and fight. A politician has the attributes name (of type String) and diplomacy (of type int). Diplomacy is the ability to outwit an adversary without using force. From this description identify a superclass as well as two subclasses. Each of these three classes need to have a default constructor, a constructor with parameters for all the instance variables in that class (as well as any instance variables inherited from a superclass) accessor (get) and mutator (set) methods for all instance variables and a toString method. The toString method needs to return a string representation of the object. Also write a main method for each class in which that class is…Write the following program in C++.
