java嘅好處同壞處

On the surface, Java and Visual Basic share some common and compelling characteristics. Both are comparatively easy to learn and to begin developing useful, small programs. In addition, both have very comprehensive APIs (Application Programming Interfaces) with the latest in Web and n-tier developments. Indeed if can't find what you need directly in the language, both have a wealth of third-party tools, utilities and components available to complete their effectiveness.

Finally, both languages have the critical advantage of many modes of deployment. Java or Visual Basic code can stand alone, be bolted on as components of a large system, or act as server-side linchpins between legacy systems, data sources, and PC and/or Web browser clients. This is why Java and Visual Basic should emerge as the dominant programming languages over the next five to 10 years.

However, there are three major differences between the two languages. First, as noted previously, Java has been built from the ground up as an OO language, while Visual Basic is gradually acquiring complete OO capabilities. Second, Java has a number of security and reliability features (security model, strong typing, simplified memory model, etc.) built right into its core design.

But the third, and perhaps the critical difference, is that Java is cross-platform - running on just about any combination of hardware and operating system - while Visual Basic is master of Windows. Visual Basic runs on windows 9x, NT, 2000, and CE. However, Visual Basic no longer supports Windows 3.x, while Java does.
