原创《Thinking in Java》学习笔记——第七章：多形性

第七章：多形性“对于面向对象的程序设计语言，多型性是第三种最基本的特征（前两种是数据抽象和继承。”“多形性”（Polymorphism）从另一个角度将接口从具体的实施细节中分离出来，亦即实现了“是什么”与“怎样做”两个模块的分离。利用多形性的概念，代码的组织以及可读性均能获得改善。7.1 上塑造型取得一个对象句柄，并将其作为基础类型句柄使用的行为就叫作“上溯造型”——因为继承树的画

原创《Thinking in Java》学习笔记——第六章：类再生

第六章：类再生“Java 引人注目的一项特性是代码的重复使用或者再生。但最具革命意义的是，除代码的复制和修改以外，我们还能做多得多的其他事情。”但这样做必须保证不会干扰原有的代码。我们将介绍两个达到这一目标的方法。第一个最简单：在新类里简单地创建原有类的对象。我们把这种方法叫作“合成”，因为新类由现有类的对象合并而成。我们只是简单地重复利用代码的功能，而不是采用它的形式。第二种方法

原创《Thinking in Java》学习笔记——第五章：隐藏实施过程

第五章：隐藏实施过程“进行面向对象的设计时，一项基本的考虑是：如何将发生变化的东西与保持不变的东西分隔开。”为解决这个问题，Java 推出了“访问指示符”的概念，允许库创建者声明哪些东西是客户程序员可以使用的，哪些是不可使用的。这种访问控制的级别在“最大访问”和“最小访问”的范围之间，分别包括：public，“友好的”（无关键字），protected 以及private。这是通过Java

原创《Thinking in Java》学习笔记——第四章：初始化和清除

第四章：初始化和清除4.1 用构建器自动初始化对于方法的创建，可将其想象成为自己写的每个类都调用一次initialize()。这个名字提醒我们在使用对象之前，应首先进行这样的调用。在Java 中，提供了名为“构建器”的一种特殊方法，所以类的设计者可担保每个对象都会得到正确的初始化。构建器的名字与类名相同。请注意所有方法首字母小写的编码规则并不适用于构建器。这是由于构建器的名字必须与类名

原创《Thinking in Java》学习笔记——第三章：控制程序流程

第三章：控制程序流程“就象任何有感知的生物一样，程序必须能操纵自己的世界，在执行过程中作出判断与选择。”在Java 里，我们利用运算符操纵对象和数据，并用执行控制语句作出选择。3.1 使用Java运算符运算符以一个或多个自变量为基础，可生成一个新值。自变量采用与原始方法调用不同的一种形式，但效果是相同的。加号（+）、减号和负号（-）、乘号（*）、除号（/）以及等号（=）的用法与

原创《Thinking in Java》学习笔记——第二章：一切都是对象

第二章：一切都是对象“尽管以C++为基础，但Java 是一种更纯粹的面向对象程序设计语言”。2.1 用句柄操纵对象每种编程语言都有自己的数据处理方式。有些时候，程序员必须时刻留意准备处理的是什么类型。您曾利用一些特殊语法直接操作过对象，或处理过一些间接表示的对象吗（C 或C++里的指针）？所有这些在Java 里都得到了简化，任何东西都可看作对象。因此，我们可采用一种统一的语法，任何地方

原创《Thinking in Java》学习笔记——第一章：对象入门

第一章：对象入门思考对象的时候，需要采用形象思维，而不是程序化的思维。1.1 抽象的进步所有编程语言的最终目的都是提供一种“抽象”方法。一种较有争议的说法是：解决问题的复杂程度直接取决于抽象的种类及质量。这儿的“种类”是指准备对什么进行“抽象”？OOP 允许我们根据问题来描述问题，而不是根据方案。然而，仍有一个联系途径回到计算机。每个对象都类似一台小计算机；它们有自己的状态，而且可要求

The Linux System Administrator's Guide

This is the third book in the main LDP series, and assumes knowledge of everything in the Installation and Users' Guides. It will cover all of the aspects of keeping the system running, handling user accounts, backups, configuration of the system, installing and upgrading software, and more. Whereas some of this information is in the Installation Guide (just to get the system off the ground) this book should be much more complete.

Pocket Linux Guide

The Pocket Linux Guide is for anyone interested in learning the techniques of building a GNU/Linux system from source code. The guide is structured as a project that builds a small diskette-based GNU/Linux system called Pocket Linux. Each chapter explores a small piece of the overall system explaining how it works, why it is needed and how to build it. After completing the Pocket Linux project, readers should possess an enhanced knowledge of what makes GNU/Linux systems work as well as the confidence to explore larger, more complex source-code-only projects.

Linux Network Administrators Guide

This document is designed to be a resource for those Linux users wishing to seek clarification on Linux/UNIX/POSIX related terms and jargon. At approximately 24000 definitions and two thousand pages it is one of the largest Linux related dictionaries currently available. Due to the rapid rate at which new terms are being created it has been decided that this will be an active project. We welcome input into the content of this document. At this moment in time half yearly updates are being envisaged.

Linux on the Road

Though there are laptop, notebook, PDA and mobile phone related HOWTOs available already, this guide contains a concise survey of documents related to mobile computer devices. Also Linux features, such as installation methods for laptops, notebooks and PDAs as well as configurations for different (network) environments are described. Although there are some caveats, Linux is a better choice for mobile computer devices than most other operating systems. Because it supports numerous installation methods, works in many heterogenoues environments and needs smaller resources.

Introduction to Linux - A Hands on Guide

This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter. For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. We hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Advanced Bash-Scripting Guide.mobi

This document is both a tutorial and a reference on shell scripting with Bash. It assumes no previous knowledge of scripting or programming, but progresses rapidly toward an intermediate/advanced level of instruction. The exercises and heavily-commented examples invite active reader participation. Still, it is a work in progress. The intention is to add much supplementary material in future updates to this document, as it evolves into a comprehensive book that matches or surpasses any of the shell scripting manuals in print.mobi format
