Why Java important to internet...?

 WThe Internet helped catapult Java to the forefront of programming, and Java, in turn, has had a profound effect on the Internet. The reason is quite simple: Java expands the universe of objects that can move about freely in cyberspace. 

Java can be used to create two types of programs : applications and applets. An application is a program that runs on your computer, under the operating system of that computer. An applet is an application designed to be transmitted over the Internet and executed by a Java-compatible web browser. An applet is actually a tiny Java program, dynamically downloaded across the network, just like an image, sound file, or video clip. The The important difference is that an applet is an intelligent program, not just an animation or media file. In other words, an applet is a program that react to user input and dynamically changes. Many types of computers and operating systems are in use throughout the world-and many are connected to the Internet. For programs to be dynamically downloaded to all the various types of platforms connected to the Internet, some means of generating portable executable code is needed. Indeed, Java's solution to these problems is both elegant and efficient.
