JAVA PROGRAMMING (TRUE OR FALSE) No further explaination needed. Classes in the java·lang package may be used directly if they are imported first using an import statement(True/False) The fields and methods of a child/sub class are only those inherited from the parent/super class.(True/False) A reference/object of super class type can hold/assume any object of its sub class type.(True/False) An import statement is necessary to use/access a classin the same package.(True/False) A private data field is accessible only by other classes via the exposed methods of its class.(True/False)

oop using c++ please give me full answer thanks Write a Program that implements Base class calculator and a Derived class scientific calculator, The Derived class should take the basic operations i.e. add, divide, subtract from calculator. However it should have its own methods such as square root.

5. State whether the following statements are TRUE or FALSE (PS: No explanation is needed and very optional)(a) One of the striking features of object-oriented programming is the division of programs into objects that represent real-world entities.(b) Inheritance means ability to reuse the data values of one object by other objects.(c) Wrapping up of different types into a single unit is known as encapsulation.(d) One problem with OOP is that once a class is created, it can never be changed.(e) Object-oriented programs are executed much faster than conventional programs.

Explain how composition contributes to reusability. Distinguish between IS-A and Has-A rules.

(Java) The Abstract Art Class Write an abstract class as follows: The class is named Art It inherits from the Comparable interface It has a private String member variable named name It has a private String member variable named artist It has a private int member variable called year It has a default constructor that assigns the values "No name" to name, "No artist" to artist and -1 to the year. This default constructor calls the three argument constructor. It has a three-argument constructor to assign values to the name, artist and year variables. It has a copy constructor that makes a copy of another non-null Art object It has getters and setters for the name, artist and year variables It has a toString() method that creates a string of artist, with name and year tabbed once on subsequent lines (see sample output) It has an equals method that compares this Art to another Object It has a compareTo method that compares in this order: 1) artist, 2) name, 3) year This class contains no…

C#   How to call a base class constructor from a derived class constructor, also how to call another constructor from one constructor in the same class? Give example.
