follows:Java.io.NotSerializableException:com.example.test.TeacherIn the case where the serializable interface is implemented, the results are as follows:Student1:student{sno=1, name= ' Rye ', teacher=teacher{tno=2, name= ' Lintong '}}student2:student{sno=1, Name= ' Rye ', teacher=teacher{tno=1, name= ' Lintong 'falseView CodeThrough the way of object flow, the deep copy is successfully completed.Three.

1. Use Randomaccessfile to achieve file compositing.2. Use serialization technology in Java to implement an object graph (100 cat cat collections, but cat owner does not need serialization) for deep replication.3. Describe the serialization of the process, application scenarios, the purpose of serial ID.===========================================================================1. Use Randomaccessfile to ach

A shallow copy (The Clone () method in the object class) refers to a copy of a variable for the base data type when the object is copied, whereas a variable for a reference type simply copies the reference.A deep copy (or Deep clone) is a

LeetCode138 Copy List with Random Pointer (deep replication of linked lists with Random pointers) Java question Question: A linked list is given such that each node contains an additional random pointer which cocould point to any node in the list or null. Return a deep copy

Today, we suddenly used the most basic java value reference and value copy, as well as the object's shortest cloning and deep cloning. Don't go round. Let's look at the example directly.Simple Type value reference, which also belongs to the value struct;Int a = 3Int B =Then, no matter how a changes the value, the value of B will not change because of a, but the f

Recently, you need to compare two object properties, one of which is oldobj, and the other is that Newobj,oldobj is the previous state of newobj, so you need to copy one of the same objects in a state of newobj, because Java does not support deep copy, So specifically wrote a method The implementation of the method is

The implementation of the method is simple and offers two ways:One is to serialize to a stream of data, provided that all objects (objects contained in the object ...) are serialized. You need to inherit the serializable interface, and if you inherit it, it's easy, if you don't inherit it, and you don't want to modify all the classes, you can use the second way.The second is to serialize the object into JSON, using JSON to implement the copy, which re

The following is a deep, shallow copy defined in C + + When you initialize another newly constructed object with a custom class type Object that has already been initialized, the copy constructor is automatically called. In other words, the copy constructor is called when the object of the class needs to be Cop
