Object Serialization supports the encoding of objects and the objects reachable from them, into a stream of bytes. Serialization also supports the complementary reconstruction of the object graph from a stream. Serialization is used for lightweight persistence and for communication via sockets or Java ...
对象序列化机制(object serialization)是java语言内建的一种对象持久化方式,通过对象序列化,可以将对象的状态信息保存未字节数组,并且可以在有需要的时候将这个字节数组通过反序列化的方式转换成对象,对象的序列化可以很容易的在JVM中的活动对象和字节数组(流)之间进行转换。
Java 1.1增添了一种有趣的特性,名为“对象序列化”(Object Serialization)。它面向那些实现了Serializable接口的对象,可将它们转换成一系列字节,并可在以后完全恢复回原来的样子。这一过程亦可通过网络进行。这意味着序列化机制能自动补偿操作系统间的差异。换句话说,可以先在Windows机器上创建一个对象,对其序列化,然后...

数据流(DataInputStream和DataOutputStream)允许我们读取和写入原始数据(如int,double)和String,而不是单个字节。 对象流(ObjectInputStream和ObjectOutputStream)进一步让我们读取和写入整个对象(如Date,ArrayList或任何自定义对象...
The typecode preceding the String in the serialization stream indicates which format was used to write the String. Arrays are represented by the following:Their ObjectStreamClass object. The number of elements. The sequence of values. The type of the values is implicit in the type of the ...
