java - Using set() in ArrayList doesn't get it updated -


मेरे पास एक क्लास MathMatrix से यह सदस्य कार्य है, जो ArrayList और lt; अर्रेलिस्ट & lt; डबल>>। 

  सार्वजनिक शून्य LUFactPivoting (MathMatrix l, MathMatrix u) LUException फेंकता है, CloneNotSupportedException {double [] Parray = {1,2,3,4}; पी = नया मथविक्टर (पैरा); MathMatrix temp = नया मैथमैट्रिक्स (यह); Int n = ncols; डबल बहु; के लिए (int k = 0; k & lt; n; k ++) {System.out.println ("ताम:" + u.toString ()); यह। द्वितीयक प्रश्नोत्तर चरण (एल, अस्थायी, कश्मीर); के लिए (int i = k + 1; i & lt; n; i ++) {if (temp.getElem (कश्मीर) == 0) System.out.println ("ZERO"); Mult = temp.getElem (i, k) / temp.getElem (k, k); एल.से.एलेम (आई, कश्मीर, बहु); के लिए (इंट जे = कश्मीर; जे एंड एलटी; एन; जे ++) {डबल न्यूवल = टेम्पी.गेट एलेम (आई, जे) - मल्टी * टेम्पी.एस्टएलेम (कश्मीर, जे); Temp.setElem (i, जे, न्यूवल); }}} के लिए (int i = 0; i & lt; n; i ++) {l.setElem (i, i, 1.0); } के लिए (int i = 0; i & lt; n; i ++) {for (int j = i; j & lt; n; j ++) {u.setElem (i, जे, temp.getElem (i, j)); }}}

मैं ArrayList.set () का उपयोग कर रहा / रही हूं, लेकिन जब मैं this.partialPivotingStep (l, temp) को कॉल करता हूं तो ऑब्जेक्ट अपडेट नहीं होता है , कश्मीर) , इसलिए ऑब्जेक्ट अस्थायी एक ही रूप में आरक्षित रहता है जब मैं इसे एक तर्क के रूप में पास करता हूं (लेकिन जब मैं इसे LUFactPivoting में उपयोग करता हूं) समस्या क्या है?

scala - Play Framework - how to bind form to a session field -

Is there any way, I can get some parameters from the header, cookies (log in userId in my case) , And then apply it in a form which I know who will deposit the ticket? SupportForm supportForm: form [supportTicket] = form (mapping ("question" -> text, "priority" -> text) (apply support ticket. (HelpText.update) What are the good practices here? What is the call to apply the request, when I can use it (and also a good practice?) Edit An issue, absolutely deceiving anyone if I were to create a hidden area with this value. It could Ript, but the issue may be re-used in any way to verify and return the form, it can not be sure how it ....

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. .. [...

I ran into this problem while trying to reactor one of my modules in the object-oriented code. I compressed it down to the bottom. Here is the list of 3 files I am using: _mypkg.pm: Usage _debug; Use _debug dprint; Package mypkg; Sub New {my ($ class,% args) = @_; My $ self = blessing {}, $ square; DPPrint "PKG \ n"; Return $ self; } 1; _debug.pm: # package mydebug; # Getting this line gets an error 500 $ my bprint = ""; Sub print_now {print "print:". $ Bprint; $ Bprint = "";} Subprint {$ bprint. = "@_"; } Subdeprint {bprint @_; } 1; testfile.cgi: #! / Usr / bin / perl is required '_mypkg.pm'; #require '_debug.pm'; #use_debug; Use _debug dprint; Print "content-type: text / html \ n \ n"; DePrint "First & lt; br & gt; \ n"; & Amp; Print_now; My $ somepkg = mypkg- & gt; new (); DePrint "Second & lt; br & gt; \ n"; & Amp; Print_now; As they a...
