What is the difference between .net and java

The differences between .net and Java are: .net is easier to get started with than Java, .net allows mixed language development but Java does not, Java provides more encryption algorithms than .net, .net has both graphical interface and command line methods to modify security configuration parameters, while Java only has the former, etc.

For beginners who are preparing to learn programming languages. Net and Java are the two technologies that beginners first consider, but many people are Confused whether I should learn java or .net. Everyone has their own opinions on these two technologies. Today I will introduce to you the differences between the two. Through this article, I hope to help you understand the advantages and disadvantages of .net and java

.NET

.NET is a new software operating platform launched by Microsoft, which includes a complete range of applications With a wide range of technologies, .NET has brought many new technologies to website management system development, especially its "mixed language" development method, which has brought great convenience. And it is the first software running platform to support mixed development of multiple languages.

##Java

The Java language is an object-oriented language born in the 1990s. It absorbs many advantages of C. Its biggest feature is "cross-platform". Because it well meets the requirements of high-level languages ​​for information systems in the Internet era, it has been widely used in practice. With the development of time, Java has occupied a mainstream position in the field of enterprise information system development, forming a complete set of technical systems and achieving great success

The difference between .NET and Java

(1) How easy it is to get started

.Net is quick to get started, and you don’t need to learn a lot of open source like Java developers do Framework and then learn to build technical architecture, development environment and other knowledge, and it has many Chinese materials for reference. Can meet the needs of beginners. The entry barrier for Java is relatively high, it takes a high-end route, and most of the materials are in English, which is difficult to learn.

(2) Platform architecture

The .NET framework includes a series of languages ​​such as C, VB.NET and C#; and a set of operations similar to the JAVA virtual machine environment; and a set of API interfaces that tend to be compatible with the WINDOWS system. Its runtime environment may exist in a browser, a WEB SERVER, or in the operating system.

The JAVA platform includes language, virtual machine, and API library. Due to the use of a virtual machine mechanism, the JAVA language has only one version on all platforms, so it uses the RMI protocol for remote communication; Microsoft uses DCOM in the .NET framework, which is now gradually evolving into SOAP.

(3) Encryption method: algorithm

.NET mainly provides the following categories of encryption algorithms for the website management system: asymmetric algorithm, HASH algorithm, symmetric algorithm , Random number generation method. JAVA provides more encryption algorithms, but fewer third-party vendors can provide their own algorithms in JAVA

(4) Security configuration

In the .NET platform, There are two ways to modify security configuration parameters: graphical interface and command line. Mscorcfg.msc is a graphical interface mode, and Caspol.exe provides a command line mode, suitable for batch processing or text configuration. The JAVA platform only provides the graphical interface tool policytool.exe. Unlike .NET, the name and location of its target object (configuration file) are not fixed. .NET defines security profiles in different scopes: system scope, local machine scope, and this user scope. When there is a configuration conflict, in principle, a small range of parameters has priority. The core configuration files of JAVA and J2EE are saved in fixed locations, but the extended configuration files vary from manufacturer to manufacturer.

(5) Secure communication: Platform

.NET only uses SSL to protect HTTP transmission in IIS-based applications. For non-IIS applications, .NET cannot protect Data in transit. In JAVA, JSSE provides platform-level services to ensure communication security based on TCP/IP. Except for IIS, .NET does not provide any other standard solution for platform-level communication protection, but JAVA provides a complete solution in this regard.
