(More than 1 answer can be chosen)arrow_forwardIn number theory, a value can be categorized as a natural number (a whole number >0, often denoted ℕ), an integer (zero or a positive or negative whole number, including the natural numbers, often denoted ℤ), or a real number (which includes the natural numbers and integers, along with all other positive and negative numbers that are not integers, often denoted ℝ). a) write a definition for a number class that contains: (i) A single field suitable for storing either a natural number, or an integer, or a real number; (ii) Setter and getter methods for manipulating this field; (iii) A constructor that initializes new objects of number to have the value 1 (unity); (iv) a method that determines which kind of number is currently stored (returning 0 if the number is real and an integer and a natural number, 1 if the number is real and integer but not a natural number, and 2 if the number is real but neither an integer nor a natural number) Java code neededarrow_forward
- Explain why accessors to private types are preferable than making the types public for the three reasons listed below.arrow_forwardNovice: How can i access a main class objects from outside the function? / Better Alternative? If i have 4 Student objects how can i print the information for the specific object given one parameter about the class, like the students Idnumber. What i came up with was making a checkId void function that takes the user input and runs an if else chain checking if the Id belongs to student 1-4 then printing the details of that classes object with the void function print. ideally i would want the if-else chain in the checkId function to call the print( student1-4) class object but im not sure how to properly do that. i dont think this is the best way to go about it, if you have any recommendations or alternatives please help me out.arrow_forwardWhat effect does it have on a class's dependencies if it is called "incomplete" or "insufficient," which are two of the most important things about a well-designed class?arrow_forward
- C++ Language Please Write a program that implements four classes: NPC, Flying, Walking, and Generic for a fantasy roleplaying game. Each class should have the following attributes and methods: NPC -a parent class that defines methods and an attribute common to all non-player characters (npc) in the game. a private string variable named name, for storing the name of the npc. a default constructor for setting name to "placeholder". an overloaded constructor that sets name to a string argument passed to it. setName - a mutator for updating the name attribute getName - an accessor for returning the npc name printStats - a pure virtual function that will be overridden by each NPC subclass. Flying - a subclass of NPC that defines a flying npc in the game a private int variable named flightSpeed for tracking the speed of the npc. a default constructor for setting flightSpeed to 0 and name to "Flying" using setName. setFlightSpeed - a mutator that accepts an integer as it's only argument…arrow_forwardIn a class definition, is the body of any method definition ever part of the class interface?arrow_forwardclassarrow_forward
