1 protected native Object clone () throws Clonenotsupportedexception; 1. The method is modified by native keyword The native keyword in Java indicates that this method is a local method, "Java native description." Moreover, the native modified method performs more efficiently than native . 2. The method is modified by protected When a class overrides the Clone () method, it needs to be modified to the p

Undoubtedly, the launch of PHP5 has a profound significance for the development of network applications. This is not just because it is highly backward compatible with PHP4. Of course, PHP5 data packets have powerful object models and a set of new functions and libraries, not to mention its portable exception mechanism, which gives it the ability to effectively handle errors and abnormal events. Write files to the server using PHP Of course, when we use the word "function, we are talking about n

Now clone is no longer a new word. With the advent of "Dolly", it is indeed a "fire" for a while. This concept also exists in Java, it allows us to easily create a copy of an object. Let's take a look at how the clone mechanism works in Java? 1. Clone copy assume that there is currently an employee object, which is employee Toby = new employee ("cmtober", 5000)

One of the advantages 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, especially programmers who learn Java before C and C + +. 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. For example, when a function

With the development of computer technology and the popularization of computers, there are large and small "hacker" website and more and more simple tools, so that the current attacks become increasingly frequent, the computer or server embedded Trojans are more and more, at the same time the security awareness of the system administrator is also improving, plus anti-virus software development, The life cycle of the Trojan Horse is also getting shorter, so the attacker, after acquiring the contr

Deep copy of clone () in Java Show the shortest copy: for non-basic data types, after the clone, the two pointers point to the same memory space, so it is only a shortest copy, so if you operate on an object, the other content also changes, which is obviously unreasonable. Each object should save its own data. So we need to make a deep copy! Example of shortest copy and deep copy: Import java. util. vecto

When you learn to use Spring Cloud Config on your website, you can't copy or check out a warehouse error.

You need to implement the Cloneable interface when overriding clone, Cloneable does not define any methods.What is the meaning of that cloneable?If a class implements the Clonable,object clone method, it can return a domain-wise copy of the object, otherwise it will throw clonenotsupportedexception.Typically, an interface is implemented to indicate the behavior of a class.The Cloneable interface changes the

ClonecopySuppose there is now an employee object, employee Tobby =new employee ("Cmtobby", 5000), passOften we will have this assignment Employee Cindyelf=tobby, this time simply copy a bit reference, cindyelf and Tobby all point to the same object in memory

Section 5-clone the object model in PHP5 to call the object through reference, but sometimes you may want to create a copy of the object and expect that the change of the original object will not affect the copy. for this purpose, PHP defines a special method called _ clone. like _ construct and _ destruct, the front has two underscores. by default, use the _ clone
