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);

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
