add java programming syntax in html

I am working in tutorial site where i want to show Java examples in html page.It will show Java code in html like string in blue,variable in green etc. I tried by watching other sites, but its really hard to implement that manually.

Is that any pre-build css available to simply my work. where i can write code in java and they convert that in html sytax?.

Several such JavaScript libraries are available; check out this one: http://alexgorbatchev.com/SyntaxHighlighter/
