What does java web do?

Java Web is actually the sum of technologies. The Web is regarded as just a container, mainly using JavaEE Technology to achieve. In addition to various middleware (SSH, etc. 4102)

JavaWeb can actually do anything. You can use JavaWeb to create a software, an ERP, a web page, or even an online game. Ya.

There is no specific category. With the portability of Java, it is now widely used in the development of various ERP and large-scale interactive websites. To put it bluntly, it is the same as the GUI in JavaSE, except that JavaSE GUI is displayed in the form of a desktop, just like the ordinary version of QQJavaWeb is displayed in the form of a web page. Just like the web version of QQ

Java code can run on different operating systems without modification, because Java's "write once, run everywhere" philosophy is implemented by Java virtual machine (JVM). As the intermediary between the compiled Java bytecode and the operating system, the JVM translates the bytecode into specific machine instructions to ensure that the program can run independently on any platform with JVM installed.

The compilation and execution of Java programs achieve platform independence through bytecode and JVM. 1) Write Java source code and compile it into bytecode. 2) Use JVM to execute bytecode on any platform to ensure the code runs across platforms.

Java performance is closely related to hardware architecture, and understanding this relationship can significantly improve programming capabilities. 1) The JVM converts Java bytecode into machine instructions through JIT compilation, which is affected by the CPU architecture. 2) Memory management and garbage collection are affected by RAM and memory bus speed. 3) Cache and branch prediction optimize Java code execution. 4) Multi-threading and parallel processing improve performance on multi-core systems.

Using native libraries will destroy Java's platform independence, because these libraries need to be compiled separately for each operating system. 1) The native library interacts with Java through JNI, providing functions that cannot be directly implemented by Java. 2) Using native libraries increases project complexity and requires managing library files for different platforms. 3) Although native libraries can improve performance, they should be used with caution and conducted cross-platform testing.

JVM handles operating system API differences through JavaNativeInterface (JNI) and Java standard library: 1. JNI allows Java code to call local code and directly interact with the operating system API. 2. The Java standard library provides a unified API, which is internally mapped to different operating system APIs to ensure that the code runs across platforms.
