> Hello,
> In this file location, only getTime() is used for Date object, in this case,
> the light method System.currentTimeMillis() is recommended, which can avoid
> creating the temporary Date object. new Date() is a thin wrapper of method
> System.currentTimeMillis(). The performance will be greatly damaged if it is
> invoked too much times.
> According to my local testing at the same environment,
> System.currentTimeMillis() can achieve a speedup to 5 times (435ms vs
> 2073ms), when these two methods are invoked 5,000,000 times.
