When I rest my pointer over a link, it diplays information about that link
Is that Java at work?
Why are there different Jav versions?
Is Java compiled like C or interpeted like Basic?
Is this contained in Internet Explorer?

Thank You very much

Java is used for server side programming that is operating system independent. The information displayed when hovering over a hyperlink is a function of the browser, not JAVA. I believe JAVA is compiled, though Javascript is interpreted. JAVA is run through a browser which contains a plugin called a JVM (Virtual Machine).

Is that Java at work? No, that's nothing to do with Java.

Why are there different Java versions? Because the developers behind Java are constantly imrpving the language, adding new features etc.

Is Java compiled like C or interpeted like Basic? Compiled

Is this contained in Internet Explorer? No, Java is machine & operating system dependent so it's not tied into different software. You download a bit of software called the Java Virtual Machine (JVM). This interprets your compiled Java code and turns it into machine code that you computer can understand. Internet Explorer just knows to look for and use a JVM that's present on the system.
