java - Array indexing issues -

-

I'm trying to create 7 classes of a class for a loop. I can go through 7 times the loop, but once I press once I get a ArrayIndexOutOfBound error

My code is as follows: 

  data [] temperature = new data [7]; (Int i = 1; i & lt; = temperature.length + 1; i ++) {System.out.println ("Please enter temperature for day" + i); Temperature [i] = new data (input.nextDouble ()); }    
 
 
  Java array index   
 Array starts with indexes 0. The problem with your code is that you are trying to use the  8th array element that does not exist . For more information, see.  
 Your code should look something like this:  
  data [] temperature = new data [7]; // Start the loop with index 0-6 (make 7 indexes total) // index 0, for it index 6 (= temperature lining) (int i = 0; i & lt; temperature; height; i ++ ) {// Since it may seem strange to enter the temperature for day 0, notice (i + 1) System.out.println ("Please enter the temperature for the day" + (i + 1 )); Temperature [i] = new data (input.nextDouble ()); }

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...
