No, Java and JavaScript are nothing to do with each other, JavaScript is a form of EMCAScript, not Java. Every modern browser comes with a JavaScript engine that is used to understand JavaScript. so there is no need for it, no.
Javascript is basically a client side scripting language which is mostly used for more interactive websites, client side validation etc. Ajax is basically asynchronous javascript and XML. So it used javascript but there is a lot more to it. XMLHttpRequest object is used to interact with the server to get the real time data without refreshing the page. There are other alternatives to XMLHttpRequest object like iframe, XMLDocument object but they are not as robust as this one. So XMLHttpRequest object is activated through regular javascript actions and the request is sent to the server. Once the response is recieved, it is thrown back to the browser and diplayed in some previously unfilled variables.
Not comparable. JavaScript is a programming language. Dreamweaver is an application (which you can use to create pages with javascript, html, etc.)
There is no systemout object in JavaScript. Do you mean Java?
