This article mainly explains "what are the misunderstandings about the Java language". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "what are the misunderstandings about the Java language"?

1.JAVA is an extension of HTML

JAVA is a programming language and HTML is a page description language. Apart from the fact that the new version of HTML can insert JA-VA applets into WEB pages, they have nothing in common.

2.JAVA is a programming language that is easy to learn.

No language as powerful as JAVA is simple. When it writes a demo Mini Program, it's very easy, but when it really does some important work, it takes a lot of effort. The JAVA library has more than 150 categories and interfaces, and although the entire class library is not required for many program users, classes are required for each project.

3.JAVA is a simple programming environment

Some people like to write programs using only vi editors and dbx debuggers. But PC and MAC programmers have become accustomed to using VB-style drag-and-drop table design tools or integrated development environments, which is a hassle for them. However, once similar Cafe tools from Syman-tec or Latte tools from Borland are available, the development time of JAVA will be greatly reduced.

4.JAVA will become the unified programming language for all platforms

In theory, this is possible. But this is not to say that users have been given the most convenient way to develop applications. The development of JAVA applications is not (and may never be) as good as Windows applications developed in MFC or VB, and the graphical development tools provided by JAVA are too simple. We hope that the JAVA class library will become rich soon.

5.JAVA is interpretive, which is too slow for important applications on special platforms.

Many programmers spend too much time on things like user interfaces. All programs, no matter what language they are written in, will have enough time to detect the mouse. Of course, we haven't used the current version of JAVA to do CPU-intensive tasks yet. However, it is very easy to develop a compiler that converts JAVA intermediate code to cost code.

6. All JAVA programs run in the WEB page

All JAVA Mini Program (applet) runs in the WEB page. The JAVA program that runs in the browser, which is the definition of applet. But it is possible and useful to write JAVA programs that do not depend on WEB browsers to run. These programs are completely portable, and because JAVA is more convenient and has fewer errors than C++, it is a good choice for programming and the preferred starting language for learning programming. Once it is combined with interface tools and database access tools, it will be more competitive.

7.JAVA eliminates the need for CGI programming

Absolutely not. In today's technology, CGI is still the most convenient means of communication between ap-plet and the server. The server will still need the CGI language to process the information sent by applet. Of course, users can write CGI in Java, which is as simple as Perl or C.

8.JAVA will revolutionize client / server computing

It's possible. SUN has announced plans for various database class libraries, which will make it as easy to develop client / server applications with JAVA as to develop network programs with JAVA's network class libraries.

9. With JAVA, users can replace their current computers with a $500 In ┐ ternet device

It is totally unreasonable to think that people will give up rich and easy-to-use desktops to pursue machines with no external memory and limited functions. But Internet devices can be used as portable assistants for desktops. If the price is reasonable, users are certainly willing to use an Internet browser to freely choose to read the news during the meal. That's the charm of JAVA.

10.JAVA will allow the abandonment of component-based computing models

When people talk about parts, they have many different meanings. For visual controls (VisualControl), such as OCX parts that can be plugged into GUI programs, JAVA has not yet set a standard. The ability to use the CORBA interface and OpenDoc to collaborate with the distributed computing model will begin soon. At present, there is a beta version of the CORBA interface on the Internet.

Thank you for your reading, the above is the content of "what are the misunderstandings about Java language". After the study of this article, I believe you have a deeper understanding of the misunderstanding of Java language, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
