I just have a piece of code as follows
public void methodA()
{
methodB(paramA, new Class() throws AException {
Noname class
}

}
According to common jave exception practice, should I also modify methodA to
throws AException?

yes, if you don't want to catch AException in methodA

Usually you don't extend RuntimException unless you want to
halt the system when the exception is throwed.

Technically, an uncaught exception does not halt the entire jvm (if that's
what you meant by "system"). If I'm not mistaken, it ends up killing the
thread throwing the exception - of course, if that thread happens to be the
main GUI thread in a Swing app, it would indeed appear to have halted the
entire system. 8-)
