《Java核心技术卷Ⅱ　高级特性（原书第10版）》一2.4.6　为克隆使用序列化

2.4.6　为克隆使用序列化序列化机制有一种很有趣的用法：即提供了一种克隆对象的简便途径，只要对应的类是可序列化的即可。其做法很简单：直接将对象序列化到输出流中，然后将其读回。这样产生的新对象是对现有对象的一个深拷贝（deep copy）。在此过程中，我们不必将对象写出到文件中，因为可以用Byte...

《Java核心技术卷Ⅱ　高级特性（原书第10版）》一2.4.4　序列化单例和类型安全的枚举

2.4.4　序列化单例和类型安全的枚举在序列化和反序列化时，如果目标对象是唯一的，那么你必须加倍当心，这通常会在实现单例和类型安全的枚举时发生。如果你使用Java语言的enum结构，那么你就不必担心序列化，它能够正常工作。但是，假设你在维护遗留代码，其中包含下面这样的枚举类型：这种风格在枚举被添...

《Java核心技术卷Ⅱ　高级特性（原书第10版）》一2.4.3　修改默认的序列化机制

2.4.3　修改默认的序列化机制某些数据域是不可以序列化的，例如，只对本地方法有意义的存储文件句柄或窗口句柄的整数值，这种信息在稍后重新加载对象或将其传送到其他机器上时都是没有用处的。事实上，这种域的值如果不恰当，还会引起本地方法崩溃。Java拥有一种很简单的机制来防止这种域被序列化，那就是将它们...

《Java核心技术卷Ⅱ　高级特性（原书第10版）》一2.4　对象输入/输出流与序列化

2.4　对象输入/输出流与序列化当你需要存储相同类型的数据时，使用固定长度的记录格式是一个不错的选择。但是，在面向对象程序中创建的对象很少全部都具有相同的类型。例如，你可能有一个称为staff的数组，它名义上是一个Employee记录数组，但是实际上却包含诸如Manager这样的子类实例。我们当然...
