This article will try to clarify this concept.

Object | One advantage of the Java language is that it cancels the concept of pointers, but it also causes many programmers to ignore the differences between objects and references in programming, and this article tries to clarify the concept. And since Java cannot solve the problem of object duplication through simple assignment, in the development process, the Clone () method is often used to replicate objects. This article will let you know what is
This is the first of the introduction to clone technology. This article mainly introduces the basic knowledge of object clone technology.

Tips"Effective Java, third Edition" an English version has been published, the second edition of this book presumably many people have read, known as one of the four major Java books, but the second edition of 2009 published, to now nearly 8 years, but with Java 6, 7, 8, and even 9 of the release, the Java language has undergone profound changes.In the first time here translated into Chinese version. For everyone to learn to share.

Creation of objects in JavaClone is copied as its name implies, and in the Java language, the Clone method is called by the object, so the object is copied. The so-called Replication object, the first to allocate a source object and the same size of space, in this space to create a new object. So in the Java language, there are several ways to create objects?

a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by super.clone need to be modified. The method clone for class Object performs a specific cloning operation. First, if the class of this object does not implement the interface Cloneable, then a CloneNotSupportedException is thrown. Note that all arrays are considered to implement the interface Cloneable. Otherw

The Clone method returns a copy of the instance object, typically X.clone ()! = X | | X.clone (). GetClass () = = X.getclass () | | X.clone (). Equals (x) is also true, but is not strictly required, and we can override this method by overriding it.protectednativeclonethrows CloneNotSupportedException;As you can see, clone is a local method that may throw a clonenotsupportedexception exception, and under wha
