how to get the current date and time of the system in java -

-

मुझे सिस्टम की वर्तमान दिनांक और समय प्राप्त करने की आवश्यकता है I जावा में और एक शर्त डाल दी है कि अगर इसकी 12 PM तो कुछ लोगों को मेल भेजें।

असल में एक टाइमर । तो मैं इसे कैसे प्राप्त कर सकता हूं? मैं क्वार्टज टाइमर या crontab अभिव्यक्ति का उपयोग नहीं करना चाहता, लेकिन इसे केवल जावा में करना है।

कृपया एक उदाहरण की सहायता से समझाएं।

आप समय के साथ तिथि प्राप्त कर सकते हैं 

  आयात करें java.text.SimpleDateFormat; Import java.util.Calendar;

और कोड 

  कैलेंडर चालूडेटा = कैलेंडर.जस्ट इन्स्टेंस (); SimpleDateFormat formatter = नया सरलडेटफ़ॉर्मेट ("डीडी-एमएम-वाई वाई वाई वाई-एचएच: मिमी: एसएस"); स्ट्रिंग दिनांकनौ = formatter.format (currentDate.getTime ()); Println (dateNow);

c# - How to know the number of Threads created and limit the Tasks accordingly -

-
It is very clear that with task as async / await Instead of calling the asynchronous call threads , my question is: Is there a way to monitor threads while completing these tasks? This is because I can decide an optimal number of times for the thread that the thread does not eat too many CPU cycles at the same time (the CPU is intensive to handle the work). We take an example below (output is also mentioned) Although the program is completed in 5 seconds, but it has two threads (id = 1,4 ) if I increase the number of 6 instead of 2, then it creates 4 threads I know that this is the CLR thread OS thread (which is 4 in my machine Are), but I would like to know how they are mapped O (with actions) and use the same CPU. Is there any way to get it? Test code Fixed zero main (string [] args) {RunTasksWithDelays (). ); } Static async Task Run Task with Dislay () {Stopwatch S = Stopwatch. Startup (); Console.light line ("thread id =" + thread.content.trade.manag...
