> In SampleAsyncFunction having _executorService_ and _random_ as static, but _counter_
as instance-specific will not work when someone creates a second instance of SampleAsyncFunction.
In second SampleAsyncFunction the _counter_ will be 0 and we will re-intialize static _executorService_
and _random_, thus interfering with the first SampleAsyncFunction object.
> To fix this example and make it clearer, make _executorService_ and _random_ instance-specific.
That will make _counter_ redundant; also synchronization on class will no longer be needed.
