Instance variables hold values that must be referenced by more than one method, constructor or block, or essential parts of an object's state that must be present throughout the class.

See lessCan java be said to be the complete object-oriented programming language?
No! Java is not a "PURE" Object Oriented Language , because it uses primitive data types such as (int,float,char...etc). The developers of java could have made these primitive data types as objects(like String... etc), but the primitive data types such as int float... are more faster than objects!

A database management system (or DBMS) is essentially nothing more than a computerized data-keeping system. Users of the system are given facilities to perform several kinds of operations on such a system for either manipulation of the data in the database or the management of the database structureRead more

See lessWhat is functional testing?
Functional testing is a quality assurance process and a type of black-box testing that bases its test cases on the specifications of the software component under test. Functions are tested by feeding them input and examining the output, and internal program structure is rarely considered.
