Explanation / Answer

1)Ans:
B)structured data abstraction
  
Means:simply Abstract Data Type and Data Structure.

Abstract Data Type: is a definition of new type, describes its properties and operations
Data Structure: It is an implementation of Abstract Data Type. Many Abstract Data Type can be implemented as the same Data Structure.

Example: Abstract Data Type:List
   Data Structure:ArrayList, LinkedList, etc...

2)Ans:
A)basic data abstraction

Means: Data abstraction over procedural abstraction is that the data and the associated operations get specified together and hence it is easy to modify the code when data changes.

3)Ans:
A)Declaration
Means: variable is an Identifier,whose values are changing during execution of the program.
   Any variable in our program, such variables must be declared in beffore one line.
4) Ans:
B)Compiler

Means: any source code converts to machine level code internally use compiler only
like, ByteCode Definition: Set of optmized instruction generated by java compiler during compilation phase. so internally compiler is working

5) Ans:
D) object-oriented programming

6) AnS:
B) Encapsulation
Means:
Mechanisms for restricting access to internal details have several names like Information-hiding Functionlaties.

7) Ans:
A) Inline
