What is the difference between .net and java?

".net" is committed to agile, rapid development and cross-platform, and can be used to develop C/S structured software or B/S structured websites. Difference: Java is an open source cross-platform language, mainly used in website development of large and medium-sized companies; ".net" is a cross-language platform, mainly used in website development of small and medium-sized companies.

The operating environment of this tutorial: windows7 system, java8&&.NET Framework4.6, Dell G3 computer.

What is .net

.NET is a Microsoft technology platform, dedicated to agile, rapid development and cross-platform, you can use It is suitable for developing software with C/S structure (WinForm technology), such as QQ, financial management systems, etc.; it can also be used to develop websites with B/S structure, such as portals, OA systems, etc. A .NET application is an application written using the .NET Framework class library and running on the Common Language Runtime. The .NET Framework component is the core of the .NET application development environment and is responsible for program execution.

The important reasons why Microsoft launched the .NET platform: to retain Windows programmers, compete with the Java platform, and promote servers

The difference between .net and java

1. In essence,

java is an open source cross-platform language; .net is a cross-language platform.

2. In terms of web development,

java is more stable, secure, highly efficient in development, and more powerful than .net and php. java In terms of web applications, there are many java servers (tomcat, jboss, weblogic, websphere), all of which can run java projects; while .net can only run on Microsoft's IIS server, which has great limitations.

3. In terms of stand-alone software development

If you develop windows applications, .net is better, because windows and .net are both Microsoft products, so when developing In terms of window applications, .net is more compatible.

4. In terms of smart device software development,

java is stronger. You should know that the applications of android smartphones are all developed with java.

5. In terms of performance

For small and medium-sized applications, .net is more efficient and has faster browsing and downloading speeds; but it is not as good as Java after one million levels.

6. Application fields

.net: Mainly used in website development and desktop application development of small and medium-sized companies...

java: Mainly used in large and medium-sized enterprise website development, bank website development and mobile phone embedded game development...

7. Encryption method: algorithm

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

8. Security configuration

In the .NET platform, there are There are two ways to modify security configuration parameters: graphical interface and command line. However, the JAVA platform only provides the graphical interface tool policytool.exe.
