Explanation / Answer

1. Programming language construct, attributes and behaviour

The class is the programming language construct which is used for encapsulating the attributes and the behaviour of the program.

2.Break()

As the OOPs programming language are real life based programming languages the functions and method names are mostly taken from the attributes or behaviour of the classes.

3.) An interface of a class defines what messages an object can respond to.

The reason is that the interface is the only type of method that can define what messages an object can respond or display.

4.) click

The reason behind this is that the button operations happening on the screen are click and hence, this is the perfect match for the data members.

5.) All of the Above

The reason behind this is that the encapsulation,abstraction and data hiding are all one and the same i.e capsulating the data in order to secure the data from falling in wrong hands.

6.) Camel Case

The camel case technique is the most widely used and accepted way of writing the methods name .It is beginning with the capital letter followed by no punctuation marks and in between we can add capital letters ending with small case letters.

7.) 6

Class members consists of variables, constructors, methods and all the initializing blocks and if you count all the things. It adds up to 6.

8.) Only one copy, both objects always share it

There is only one copy of all the attributes and behaviours whereas they share all the things up regardlessly.

9.) UML Diagrams & Serialization.

The UML Diagrams helps us to organize the class and all the class members for big projects and to organize the program it is very important to keep the classes organized.The serialization of the classes is also very important.

10.) private.

By default all the members of the classes are private and it can be changed by using different access modifiers for the members of the classes.
