Java development kit. As you all know, Java programs can run on most machines and do not need to install any additional software. Why should we install JDK? This is because the Java program needs to translate source code into intermediate code form during development, that is, class files. The usual run Java programs do not need to install additional software refers to the compiled Java program code, the general operating system and browser installed JRE (Java Runtime Environment), and our development environment, generally need to install JDK to compile the source code. To put it plainly, the installation of JDK means that you can use JDK to install directories under the bin directory, a series of commands that may be used when using Java for program development: including javac, jar, keytool, native2ascii.exe, javaw, etc.. 2.apache. Apache is a software foundation, and many well-known open source software is run by the foundation. And we usually say Apache Software, refers to its Web server, that is used to parse a static web page of a program. With Apache, you can put a static HTML page on our computer, and other people can access our web pages by entering our computers IP address in the browser. Note that the current Apache installer name is called httpd. 3.jboss. It is also a Web server, or an application server. The difference between Java and Apache is that Apache is very fast, but it can only parse static web pages, while JBoss can parse dynamic web pages such as JSP, and the background can also parse and interact with them. Of course, JBoss has many powerful features, but here as long as the understanding of its main difference with Apache is good, Apache is very fast, but only analyze static pages; JBoss more powerful analytical dynamic pages, but the analysis of static
