Java programming Idea: The 1th Chapter Object Introduction

1.1 Abstract Process

All languages are abstract, but the type and quality of abstraction determines the complexity of solving problems.

Abstract quality characteristics of language abstract types

Modeling for machine Models

--------------------------------------------------------------------------------------------------------------- ---------------------------------

Lowest-level assembler bottom machine slightly abstract based on the underlying machine

Imperative FORTRAN/BASIC/C assembly is still based on the basic elements of the underlying machine structure is based on the machine model [solution space], so must establish a problem model

The Association of [problem Space], which is laborious and difficult to maintain

Modeling for the problem you want to solve

--------------------------------------------------------------------------------------------------------------- ---------------------------------

Early object-oriented LISP/APL specific types of problem element abstraction is only good for specific problems, beyond scope.

To address early object-oriented issues, object-oriented provides programmers with a tool that can be used to represent elements in a problem space,

Enables programmers to apply new types of objects to a new specific problem
