What is Java?
Java is a programming language introduced by Sun. It is an interpreted language with syntax rules similar to C++. Java is also a cross-platform programming language. The program written in Java language is called "Applet" (small application program). After compiling it into class files by the compiler, it is stored in the WWW page and marked on the HTML file accordingly. As long as the client software of Java is installed, the client can run the "Applet" directly on the network. Java is well suited to enterprise networks and Internet environments and is now one of the most popular and influential programming languages on the Internet. Java has many remarkable advantages, such as simplicity, object-oriented, distributed, interpretability, reliability, security, structural neutrality, portability, high performance, multithreading, and dynamism. Java dispenses with C++ features that do more harm than good and many that are rarely used. Java can run on any microprocessor, and programs developed in Java can be transmitted over the network and run on any client.
