Welcome to Java

Java is not JavaScript

Javascript was originally developed by Netscape under a different name as a lightweight scripting language embedded in the browser. Unfortunately it was decided to rename this technology as JavaScript which has caused huge amounts of confusion. JavaScript is embedded within web pages as plain text and is generally visible to anyone who knows how to look at the page source code. When used with web pages Java is used in the form of applets, and the source code is not visible to people browsing a web page.
