The following are the principle aspects of the design for versioning of serialized object streams. The default serialization mechanism will use a symbolic model for binding the fields in the stream to the fields in the corresponding class in the virtual machine. ...
The array of fields of the class that are serialized by the default mechanismFor arrays and object fields, the type of the field is included as a string which must be in "field descriptor" format (e.g., "Ljava/lang/Object;") as specified in The Java Virtual Machine Specification. Option...

Java serialization can handle objects with multiple references. When an object is serialized, all of its references are serialized as well. Let’s look at an example where twoPersonobjects share the sameAddressobject: publicclassMain{publicstaticvoidmain(String[]args){Addressaddress=newAddress("123...

对于一般的类型都会实现该Serialized接口,例如:String、Data所以我们可以直接用。 代码案例 直接应用 将对象序列化 代码语言:javascript 代码运行次数:0 运行 AI代码解释 importjava.io.FileOutputStream;importjava.io.IOException;importjava.io.ObjectOutputStream;importjava.util.Date;/** * 序列化对象(Serializable)...
