Java provides a mechanism, called object serialization where an object can be represented as a sequence of bytes that includes the object’s data as well as information about the object’s type and the types of data stored in the object. After a serialized object has been written into a f...
The serialization in Java is an example of a basic operation that needs to be reviewed to make distributed Java fully predictable and suitable for hard-real time systems. However, the most recent works in the application of Java in distributed real-time systems do not specify how a ...
For example, in the code below, the deserialized object contains null as the registration number. class Student implements Serializable { String name; Double gpa; transient String regNo; Student(String name, Double gpa, String regNo) { this.name = name; this.gpa = gpa; this.regNo = regNo; ...
In this example,person1andperson2share the sameAddressobject. Whenperson1andperson2are serialized, theAddressobject is serialized only once. During deserialization, theAddressobject is restored only once and shared byperson1andperson2. This is because Java serialization maintains the object graph, pres...
; nested exception is java.lang.ClassCastException: cannot assign instance of java.lang.String to field com.example.User.name of type java.lang.Integer in instance of com.example.User 1. 从异常信息中可以看出,出现了反序列化失败的情况。在这个例子中,尝试将一个字符串反序列化为User对象,但是发现...
Add support for java.util.ArrayList$SubList is easy. Registering a customized serializer will sovle this issue. But it comes with new porblem. Take following example: List<String> list = new ArrayList<>(); list.add("str1"); list.add("str2"); list.add("str3"); list.add("str4");...
The so-called serialization is to convert an object into a certain form, and then transmit it in a data stream. For example, an object is directly converted into a binary data stream for transmission. Of course, this object can be transformed into other forms and then transformed into a da...
It requires a class namedPerson, which is shown in the following example. C# namespaceExampleApplication{publicclassPerson{publicintPersonID {get;set; }publicstringName {get;set; }publicboolRegistered {get;set; } } } Remarks When theJavaScriptSerializerinstance is serializing a type for which a ...

If you remove a field from the middle of an object, you need to ignore the whole object during deserialization by using the skipObject method in SerializationUtils. This way you don't need to keep the serializer if you are removing the object all together. Say in the above example you als...
