java - how to make sure a String input is not a number? -


मैं एक do..while लूप का उपयोग कर रहा हूँ और मेरे समय में 

  (IntOne! = IntTwo & amp; रंगऑन! = 0 & amp; रंग दो! = 0);

समस्या यह है कि मुझे निम्न त्रुटि मिल रही है "असंगत ऑपरेंड प्रकार स्ट्रिंग और इंट"

मुझे पता है कि मेरा रंग एक और रंग दो तार हैं और मैं यह कहने का प्रयास कर रहा हूं कि वे एक पूर्णांक के बराबर नहीं हैं।

मुझे लगता है कि यह है कास्टिंग और सामान के साथ कुछ करना है लेकिन मैं इसके लिए नया हूँ और कृपया मदद की ज़रूरत है!

आपको पार्स करना चाहिए आपके स्ट्रिंग से इंट: 

  पूर्णांक.परसेआईंट (रंगऑन)

तो आपका कोड ऐसा दिखेगा: 

  जबकि (intone! = IntTwo & amp; Integer.parseInt (colorOne)! = 0 & amp; amp; Integer.parseInt (colorTwo)! = 0);

Django Celery - running scheduled tasks -

After several hours on this without the result, I really need help I'm able to run Django-Celery with my Django app and I scheduled tasks on it: dragon manage.py celeryd -E -B -l INFO Now it is time to produce and here it is that my pain begins. I have configured the cellarid as the daemon, it works, but scheduled tasks will not work. So I added -b to CELERYD_OPTS . My tasks are now run as scheduled, but these are the boring lines on my logs: [2014-02-17 22: 37: 30,738: debuts / main process] Beat: 5.00 Waking in seconds I just want to delete that line from my logs! I did not even understand what it meant. So I had configured the Selerbeat daemon, thinking it would be a cleaner and suggest a solution to the production environment. Unfortunately, when I stop the celerybeat daemon, it creates a log and a PID file but scheduled tasks do not work. Info / main process] green: ... [2014-02-17 19: 15: 41,921: information / main process] write entries. .. [...
