<पूर्व> पैकेज penny_pinch_v2; सार्वजनिक वर्ग पुरस्कार {सार्वजनिक स्थिर स्ट्रिंग [] पुरस्कार = {"पहेली", "पोस्टर", "गेंद", "गेम", "गुड़िया"}; } =========== अलग क्लास फाइल ============ पैकेज पेनी_पिनच_ v2; सार्वजनिक वर्ग RunPennyPinch {सार्वजनिक स्थिर शून्य मुख्य (स्ट्रिंग [] आर्ग्स) {System.out.print (पुरस्कार [1]); }}

मैं एक अलग कक्षा में सरणी 'पुरस्कार' तक पहुंचने की कोशिश कर रहा हूं, लेकिन यह कहता रहता है कि 'पुरस्कार' का समाधान नहीं किया जा सकता। यदि आप मुझे बता सकते हैं कि इसे कैसे ठीक किया जाए तो यह अच्छा होगा।

आपको चर के साथ प्रीफ़िक्स करना होगा चर के रूप में वर्ग का नाम RunPennyPinch वर्ग के भीतर नहीं है। 

  System.out.print (Prizes.prizes [1]);   
 आपको अपने सेट-अप के आधार पर  पुरस्कार  वर्ग भी आयात करना पड़ सकता है।

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

c++ - Qt::make_shared for creating QSharedPtr as std::make_shared for creating std::shared_ptr -

-
As stated in the Barjini Stroustrup's "A Tour of C ++", and a known C ++ 14 practice As such, someone should avoid the naked code in the new and delete . Provides std :: make_shared and std :: make_unique to create smart pointers to store allocated items in the standard library. However, it is not possible to use these routines for non-standard smart pointers, such as QT's own memory management model (with parent), but also smart pointer class like Provides QSharedPointer and QPointer (although later it is not actually a brochure indicator). My question is: Is not it convenient to create Qt analog of std :: make_shared ? To like it, QSharedPtr : Namespace Qt {template & lt; Class T, squares ... Args & gt; QSharedPointer & LT; T & gt; Make_shared (erg & amp; ... args) {return QSharedPointer & lt; T & gt; (New t (std :: forward & lt; ergos & gt; (args) ...)); }} or to create this, QPointer : named place ...
