Java is perhaps one of the most
talked about advances in Internet technology
since the World Wide Web. People in many areas
of computing are discussing Java and how it will
change the face of computing. No doubt, Java
will change the way people use the Internet and
networked applications. Java has introduced many
ideas to the World Wide Web arena, and those
ideas represent some exciting changes to the
Internet and computing.
At the heart of all the Java
talk is the Java programming language. Java is
an object-oriented programming (OOP) language
that uses many common elements from other OOP
languages, such as C++, but it adds some
enhancements to make programming Java easier.
Like any other language, Java has a particular
syntax, a structure for programs, and many
supporting applications.
The Java Developer's Kit(JDK)
contains all of the tools necessary to create
applications (or Web applets) using the Java
programming language, including the following:
| |
javac |
The Java compiler |
| |
|
|
| |
jdb |
The Java debugger |
| |
|
|
| |
javadoc |
The Java documentation
program |
| |
|
|
| |
java |
The Java Virtual Machine |
| |
|
|
| |
appletviewer |
The Java applet viewer |
Some of these Java components
might not seem so obvious, such as the Java
Virtual Machine. In using Java to program, you
do not directly access the Java Virtual Machine.
However, other commercial Web browsers that can
run Java applets use it, as does appletviewer. |
