J
Java: Java is a
network-oriented programming language invented by Sun Microsystems
that is specifically designed for writing programs that can be
safely downloaded to your computer through the Internet and
immediately run without fear of viruses or other harm to your
computer or files. Using small Java programs (called
"Applets"), Web pages can include functions such as
animations, calculators, and other fancy tricks.
We can expect to see a huge variety of features added to the Web
using Java, since you can write a Java program to do almost
anything a regular computer program can do, and then include that
Java program in a Web page.
