java - "if" statement block doesn't work correctly -


इस सवाल का पहले से ही एक उत्तर है: < / P>

  • 23 उत्तर

मुझे वास्तव में पता नहीं है यहाँ क्या हो रहा है, लेकिन मैं सर्वर-क्लाइंट अनुप्रयोग लिख रहा हूं और क्लाइंट सर्वर पर एक स्ट्रिंग भेजता है। मुझे सर्वर पर "x" स्ट्रिंग भेजने की आवश्यकता है, इसलिए यह कोड 1 चलने लगती है, लेकिन जब मैं यह करता हूं, सर्वर को कोड 3 चलाता है। सबसे मजेदार बात यह है कि System.out.println (x); कंसोल में "a" प्रिंट करता है।

यहां सर्वर कोड का एक टुकड़ा है (win7, javac compiler पर चलता है) :

<पूर्व> sInput = नया ऑब्जेक्ट इनटस्टस्ट्रीम (सॉकेट.जेट इन्पुटस्ट्रीम ()); SOutput = नया ऑब्जेक्टऑटपुटस्ट्रीम (socket.getOutputStream ()); स्ट्रिंग x = (स्ट्रिंग) sInput.readObject (); Println (x); यदि (x == "ए") {/ * * code1 * /} और यदि (x == "b") {/ * * code2 * /} और {/ * * code3 * /}

और यह वही है जो क्लाइंट करता है (ओएसएक्स, जावाक कंपाइलर चलाता है): 

  sInput = नया ऑब्जेक्ट इनटस्टस्ट्रीम (सॉकेट.जेट इन्पुटस्ट्रीम ()); SOutput = नया ऑब्जेक्टऑटपुटस्ट्रीम (socket.getOutputStream ()); स्ट्रिंग x = "a"; sOutput.writeObject (x);

मुझे इसे कैसे हल करना चाहिए?

पीएस मुझे अपवाद घोषणापत्र के बारे में पता है, उन्हें कोड कम करने के लिए निकाल दिया जाता है।

उपयोग की तुलना करने के लिए समान विधि का उपयोग करें दो तारों के मूल्य अधिक जानकारी के लिए देखें।

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 ....

c++ - Why does Visual Studio Release build break on non-executing code line -

When I created my C ++ program with the default release configuration in Visual Studio 10, I put a breakpoint on one line Who should never be reached. What confunded me was that when the program is running then it stopped at the breaking point. Adding a volatile statement and transferring this line to the break point does not break the execution of the code where the brake appears (though does not produce the same behavior as creating a minimum project with this function). Why is the "Release Debugger" (?) Step on this line and when executing breakpoints are executed? If I keep going after the break then false statement continues to return code execution. bool bounding box :: Cutting (int32_t xpos, int32_t ypos, int32_t dx, int32_t dy) const {int32_t intersectionX; Int32_t intersections; If ((dx> 0 & amp; amp; and & amp; xpos> rights) || (dx gt; Top) || (D & LT; 0 & amp; AOPO & Lt; BOT)) Return; If (DX! = 0) {intersection Y = ypos + (left...

Firefox reacting to JQuery setTimeout that doesn't apply -

& lt; - Only note the first image. I think some jquery is not working in Firefox, where there seems to be a problem ... but there is IE (I know, I know) var hover = $ ('# par1'), box = $ ('.sq1'); Hover.hover (function () {box.toggleClass ('index2');}); and var linkloc = $ ('# par1'), link = $ ('# frnt1'); Linkloc.on ('mouseenter', function () {function linkadd () {link.html ("& lt; a target = _blank href = http: //www.google.co.uk> & lt; img src = small1 .JPG / & gt; & lt; / a & gt; ");} Set Timeout (linkAD, 1500)}); Linkloc.on ('mouseleave', function () {link.html ("& lt; img src = small1.JPG />");}); I appreciate that the code can be a bit messy, but I'm still learning as I go. The problem now is that the top slice of the code is reacting down to the setout. (It revolves around time with setTimeout repeatedly) even though the name of the function is c...
