2. Class as the Basis of all Computation
Objects and Classes
Objects encapsulate state and behaviour
numerous examples; member variables; attributes
or features. Variables define state; member
methods; Operations/methods/messages/methods
define behaviour.
Classes as abstractions for sets of objects; class
as an object factory; primitive data types,
composite data types. Variable declarations for
both types; difference between the two types.
Objects as instances of a class.
Consider real life examples for explaining the
