Public members of a base class can be accessed by anything from outside the base class. Private members can be accessed only by the base class and derived classes. Protected members can be accessed by the base class and any of its descendants (child class or child of a child class). answer choices True False
Each class member (fields and methods) have an accessibility (for example, public). Select each the accessibility modifiers that a derived class inherits from the base class: abstract final interface private protected public
In-class Assignment Day 8 You should draw the hierarchy for your classes to understand how the coding should be structured. Be sure to notate any classes that are abstract. Write an abstract class for Shape. The intended subclasses are Polygon, Circle, Triangle, and Rectangle. All of these will have a name, an area, and a perimeter. (Consider which methods might be abstract.) Add a toString method that will return the information about the Shape, for example: Triangle, Area: 7.5, Perimeter: 12.0 Write the class Rectangle. A Rectangle is a Shape and should have a width and a height. When a Rectangle is outputted, it should read: Rectangle, Length: #, Width: #, Area: #, Perimeter: # Write the class for Circle. Every circle is a Shape that has a radius. Be sure to provide an accessor method (getter) for the radius. When a circle is outputted, it should read: Circle, Radius: #, Area: #, Circumference: # Write a TestShape class that has the main method, which creates…
QUESTION 5 All methods in an abstract class must also be declared abstract. True False QUESTION 6 All fields declared in an interface are treated as final and static have protected access must be initialized in the class implementing the interface have private access

Create a class Animal and Add a protected data member named id of integer type. Add get/set methods for id data member in Animal class with public access. Also provide default constructor this should initialize id to 0. Also provide parameterized constructor and toString method. Add an abstract method tellAboutSelf method to Animal class with public access Add another abstract method speak method to Animal class. Reptile, Bird, Mammal Next create the three child classes which extends form Animal class. Add a default constructor to each of the above created class. The constructor should initialize the id data member id, Reptile, Bird and Mammal, to 1, 2 and 3 respectively also it display a message “(class Name)’s default constructor”. E.g. for Bird it says “Bird’s default constructor”. Add a parameterized constructor to each of the above created class. The constructor should initialize the id data member, Reptile, Bird and Mammal, to the specified id passed to the constructor also it…
If a member is declared private in a class, can it be accessed from other classes? If a member is declared protected in a class, can it be accessed from other classes? If a member is declared public in a class, can it be accessed from other classes?
