Java is a programming language invented by Sun Microsystems. It is expressly designed for use in the distributed environment of the Internet. It was designed to have the “look and feel” of the C++ language, but it is simpler to use than C++ and enforces a completely object-oriented view of programming. Java can be used to create complete applications that may run on a single computer or be distributed among servers and clients in a network. It can also be used to build small application modules or applets for use as part of a Web page.
Java class files
These are files that contain the code required by a Java applet on your web page
Java Servlets are small programs coded in the Java programming laguage that are executed on a web server. They perform certain task and are able to produce dynamic web content – i.e generate web pages on the fly. See also JSP

Java Virtual Machine (JVM) is a Java interpreter and runtime environment. Java source code is compiled into a format called bytecode (files with a .class extension), which can then be executed by a Java interpreter. Web browsers are often equipped with Java virtual machines.
JDBC allows Java programmers to access relational databases and other tabular data sources. It is a set of methods to connect Java code to databases
Java Server Pages. Extension to the Java servlet technology. JSP pages are text documents that have a jsp extension and contain a combination of static HTML and XML like tags and scriptlets.
