今天在网上闲逛，发现了一本好书，关于JAVA和TDD的，内容介绍如下�Q?br />

Master Java 5.0 and TDD Together: Build More Robust, Professional Software

Master Java 5.0, object-oriented design, and Test-Driven Development (TDD) by learning them together. Agile Java weaves all three into a single coherent approach to building professional, robust software systems. Jeff Langr shows exactly how Java and TDD integrate throughout the entire development lifecycle, helping you leverage today's fastest, most efficient development techniques from the very outset.

Langr writes for every programmer, even those with little or no experience with Java, object-oriented development, or agile methods. He shows how to translate oral requirements into practical tests, and then how to use those tests to create reliable, high-performance Java code that solves real problems. Agile Java doesn't just teach the core features of the Java language: it presents coded test examples for each of them. This TDD-centered approach doesn't just lead to better code: it provides powerful feedback that will help you learn Java far more rapidly. The use of TDD as a learning mechanism is a landmark departure from conventional teaching techniques.

Presents an expert overview of TDD and agile programming techniques from the Java developer's perspective
Brings together practical best practices for Java, TDD, and OO design
Walks through setting up Java 5.0 and writing your first program
Covers all the basics, including strings, packages, and more
Simplifies object-oriented concepts, including classes, interfaces, polymorphism, and inheritance
Contains detailed chapters on exceptions and logging, math, I/O, reflection, multithreading, and Swing
Offers seamlessly-integrated explanations of Java 5.0's key innovations, from generics to annotations
Shows how TDD impacts system design, and vice versa
Complements any agile or traditional methodology, including Extreme Programming (XP)

E文不��太难，一般都应该可以看懂�Q��ؓ(f��)什么好书都是老外写的呢？
我想把书传上来，但是.Text�Ҏ(gu��)��件的大小好象是有限制�Q�书的名字叫

本文是�?/span> JAVA �~�程思想》第四章的读书笔�?/span>

一�?/span> 用构造函数初始化

1�Q?�?span style="FONT: 7pt 'Times New Roman'"> 函数的签名和�q�回�?/span>

构造函数可以通过不同的函数签名来�q�行重蝲。构造函数没有返回��|��q�和�q�回��gؓ(f��) void 的是不同�?/span>

1�Q?�?span style="FONT: 7pt 'Times New Roman'"> 构造函数的重蝲

如何区分构造函数的不同呢，用不同的函数�{�֐�。函数签名的��序不同都可以，但是�q�样的编�E�风格是不好的�?/span>

函数的签名会(x��)上升转型�Q�当没有合适的函数�{�֐�出现的时候）�Q�但是不�?x��)窄化�{型，你必��要昄��的进行强制类型�{换�?/span>

不能�?/span> return value 的不同作为重载的标准�?/span>

当程序提供了构造函��C��后，�pȝ��׃��在提供默认的构造函��C��?/span>

This 关键字指的是当前对象�Q�有�?/span> this 后，可以在构造函��C��以如下的方式调用

Class A {
    A () {…}
    A( int a, char b) {… }
    A( int a, char b, float c) {
        This(a,b); // 注意�Q�只能调用一��?/span>
    }
}

你无法在 static 函数中调�?/span> non-static 函数�Q�但是你可以�?/span> non-static 中调�?/span> static 函数�?/span>

二�?/span> �cȝ��清理

JAVA 的垃圑֛�收机制只能回�?/span> new 出来的对象，但是你的对象不是 new 出来的而获得的“特�D�”内存，那么 JAVA 的垃圑֛�收就不能处理�Q�这样就必须�?/span> finalize() 函数来释放你的“特�D�”内存�?/span>

JAVA 的清理方式是先调用你�?/span> finalize() �Q�然后在下次垃圾回收的时候来清理你的“特�D�”内存�?/span>

关键的三句话�Q?/span>

垃圾回收不等于析构；

你的对象可能不被回收�Q?/span>

垃圾回收动作只回收内存�?/span>

�?/span> System.gc() 可以用来��l�结动作的发�?/span>
