java - How to sort bidimensional ArrayList? -

-

मेरे पास एक ArrayList & lt; ArrayList & lt; स्ट्रिंग & gt; & gt; यह दो मानों की एक सूची है : 

  जॉन, 12.3 मार्कस, 35.0 मुकदमा, 11.4   
 राशि के अनुसार सूची को कैसे सॉर्ट करना है? यदि इस मामले में एक ArrayList के ArrayList का उपयोग करने से बेहतर तरीका है, तो कृपया मुझे बताएं और मुझे बताएं कि इसे कैसे सॉर्ट करना है। धन्यवाद।   
 
 
 इसके बजाय मैं आपको एक क्लास का उपयोग करने के लिए सलाह देगी और वर्ग की तरह प्रयोग करेगी जैसे सॉर्ट करने के लिए तुलनीय या तुलनित्र । इस तरह से कुछ:  <पूर्व>  वर्ग व्यक्ति लागू करता है तुलनात्मक & lt; व्यक्ति & gt; {स्ट्रिंग का नाम; दोहरी राशि; व्यक्ति (स्ट्रिंग एन, डबल डी) {name = n; राशि = डी; } सार्वजनिक अंतर की तुलना करने के लिए (अन्य व्यक्ति) {यदि (राशि! = अन्य। राशि) Double.compare (राशि, अन्य। संख्या) लौटाता है; Return name.compareTo (अन्य। नाम); }}   
 और लागू करना और समझना आसान 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...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
