Simplistically put: It is a technology that has the programming language as well as the platform. You can use it for creating and running software applications.

The java runtime provides a platform to run java applications and javascripts. While there are some standalone java apps, the vast majority of them are web related. Your browser looks to see if you have the runtime before it launches the web based java app.

A good example is my ISP's webmail client - its all in java, and if I didn't have a java runtime, I would get an error directing me to go get a copy and install it.

Does that help?

I thought Java runtime is not needed for JavaScript - JavaScript being totally different from Java.

Now the big question is what does Java and JavaScript do for you.

Well, it opens opportunities for web site builders to plonk trojans, spyware, malware and all sorts of other garbage onto your system without you knowing it. It also increases the amount of download for a site, in most cases.

Yahoo use it extensively to run their Yahoo games and their spyware.

What does Java do for a web designer, it allows them to get lazy and make web sites without having to really know what they're doing. But it does allow them to run applications through the web site, most commonly used for games, loading spyware, trojans etc. Some people do use it for running more complex web sites where they have interaction with databases - for that, I hear, it's very good. But so are many other programs that aren't so risky - they just require the programmer to learn about what he's doing.

I've seen some very good web sites made up on java and JavaScript - sadly they make up less than .0001% of web sites made up with Java and JavaScript. The bulk are boated garbage.

it's included with the browser.
the two are not related.
except for being computer languages
not in JRE far as I know

I'm using Windows XP, Internet Explorer and on Comcast Services with Norton Security. I don't porogram, and not a gammer. I just got a note on my Desktop that a Java update is required/ I don't want to bog down my system with stuff I don't need. nor play games. It says it for security and media does that mean I need it for Windows movie player or others?
Can I delete the old Java releases as well?

by nicknielsen

If you don't go to any sites that require it or use Java web applications.

And yes, even if you update the Java, you can delete all those old releases. If you want to update the Java and delete the old releases the easy way, there's a neat freeware app called Java Ra.

See java comes in two parts the JDK and the jre . JDK is installed by people who want to do development and run programs . Jre is used for just running ur apps .

If u already have apps then u just need jre point ur path variable to the java in the jre bin and run the apps

but if u wanna compile programs and run them
then u need jdk only

hope this helps
