Abstraction

Abstraction means ignoring irrelevant features, properties, or functions and emphasizing the relevant ones...relevant to the given project (with an eye to future reuse in similar projects).

The Class Concept

A class is a collection of objects (or values) and a corresponding set of methods.  A class encapsulates the data representation and makes data access possible at a higher level of abstraction. Example 1: A set of vehicles with operations for starting, stopping, driving, get km/liter, etc. Example 2: A time interval, start time, end time, duration, overlapping intervals, etc. Example 3: A string, upper case, compare, lower case, etc.  str.equals(otherStr) – class/Java style   strcmp(str, otherStr) – C style
