Living on Nano Time: Using System.nanoTime

Moore's law is the name of a well-known observation that the number of transistors in a computer and its processing speed increase exponentially over time. Gordon Moore, as director of research and development at Fairchild Semiconductor, made the observation way back in 1965. So far, it still holds true.

With much faster computers now than we had when Java first arrived, millisecond timing is no longer good enough for many applications. Perhaps you have used the java.lang.System class to obtain timing information for a method call or a section of code, using the currentTimeMillis method . We'd often ...
