How to use Matcher in multithreaded app?

[Nobody/Anonymous]

I have a trouble when try to use Matcher in multithreaded applications.
I found the following guide from Jregex website:
"the typical tactics in multithreaded applications is to have one Pattern instance per expression(a singleton), and one Matcher object per thread."

Who can show me the Java code ?

I interpret it as Pattern objects can be static (shared between multiple threads), whereas each thread uses its own Matcher object (local variable instead of a static member).
