How to talk about the advantages of Java website development process, I believe that many inexperienced people do not know what to do about it. Therefore, this paper summarizes the causes and solutions of the problems. Through this article, I hope you can solve this problem.

Java is a widely used network programming language. With the development of Internet, Java language has been more and more widely used because of its strong vitality. Java language is respected because it can be called a new generation programming language, which has many advantages, such as object-oriented, good portability, independent of hardware, strong system security, concurrent mechanism, high performance, and provides tea website distribution, multi-thread, dynamic support.

As an important development tool, Java has seven main features: security, core API, open standards, distributed and dynamic structure, object-oriented, multithreading and memory management.

(1) Security

Security is the most important issue for Internet developers. Users are most afraid of two things: confidential information is stolen or computer systems are compromised by hackers. The built-in security of Java solves these two problems.

The security model of Java has three basic components: class loader, bytecode validator, and security manager. The bytecode validator ensures that the tea website of the Java program is compiled correctly and follows the access restrictions of VM. The next layer of security is provided by the class loader. The class loader separates classes from different servers and distinguishes them from local classes when they get classes from the network. With this separation, the class loader can prevent classes loaded online from pretending to be standard built-in / built-in classes, or from interfering with loading classes from other servers.

The security manager implements the security policy for VM. The security policy determines what activities VM can do and under what conditions. For example, documents in disk files are stored and loaded in the input / output of the file. VM has the ability to read or write human files, but it must first be checked by the tea website source code security manager Imax O. This allows the security manager to determine whether Java programs can access disk files without causing malicious harm to the file system.

Security managers are commonly used to prevent warning errors. For example, in the browser netscape navigator that Java allows, the security policy does not even allow file access. The security manager itself is also written in Java (which is a Java class file), so it can be overridden if necessary. At the same time, Java has measures to prevent hostile Java programs from writing their own security policies. These measures will prevent other security managers from being added to the system when the web browser is running.

In summary, Java's security measures ensure that Java programs operate under VM rules, preventing unauthorized programs from accessing system resources that contain proprietary information or endangering the integrity of clients.

(2) Core API

API, the application programming interface, is a functional library used by application developers to construct software more quickly. The core API of Java provides a set of functions commonly used on system platforms.

API is divided into several software packages. They are classes that perform related functions respectively. One of these packages contains some core language features, such as word processing and error handling, without which it would be almost impossible to write Java programs. Other software packages include utilities, networking, iUnix, graphical user interface tools, and interfaces with web browsers.

(3) Open standards

Java VM has appeared in more than a dozen different hardware and operating system combinations. The advantage of Java's cross-platform capability is that Java class files do not need to be pre-compiled for each platform. Java applications written in the system can run on all system platforms that support Java. Another key to Java as a cross-platform development tool is that there is a dedicated core feature set on each platform. Core Java? API's implementation of all Java is the same, and there is no need to write native code for desktop applications.

(4) distributed and dynamic structure

In the Windows operating system, some programs can be replaced with dynamic link libraries (DLL) for dynamic sharing or loading (that is, while the program is running), and the operating system completes the first phase of linking during execution. Using shared dll can save memory and improve the modularity of the software.

Java further makes use of the dynamic library. VM class loader can fetch class files from disk and obtain them from the network at the same time. Java applications are both dynamic and distributed. This feature enables the viewer of the available Java to automatically adopt the protocols available on the new Web address. In this way, the Java application does not need to retrieve the useless part of the program. Java has the ability to change the distributed model of software used in the industry.
