Explanation / Answer

1. only A,B, and D

2. Constructors
Explaination : Class Constructor name must be same as its class name and Constructor must have no explicit return type

3. Only A & B
Explaination : If a class has multiple methods having same name but different in parameters, it is known as Method Overloading

4. (A) In object-oriented programming we design the program as a set of cooperating methods

5. Volume()

6. C [constructor is automatically created for you if you do not define one]
Explaination : Default constructor is creaed by JVM if no constructor define

7. Implementation
