java - No suitable driver found when invoking DriverManager from class constructor -


पुस्तकालय में mysql-connector-java-5.1.22-bin.jar जोड़ा गया। एक वर्ग बनाया, सभी java.sql संकुल आयात किया। सार्वजनिक स्थिर शून्य मुख्य और एक कन्स्ट्रक्टर है। मुख्य में, लाइन को जोड़ा गया ... 

  DriverManager.getConnection ("jdbc: mysql: // स्थानीय होस्ट / लुकअप", "रूट", "डमीपीडब्ल्यूड" )   
 यह एक अपवाद नहीं डालता है और मैं डेटाबेस के साथ सामान कर सकता हूँ कंस्ट्रक्टर पर एक ही पंक्ति जोड़ें और मुझे एक त्रुटि मिलती है:  
 
 कोई उपयुक्त ड्राइवर नहीं मिला ...   
 यह  मुख्य में क्यों काम करेगा  विधि लेकिन कक्षा निर्माता के अंदर नहीं?   
 
 
 इस तरह एक DriverShim क्लास का उपयोग करने की कोशिश करें :  
 इसलिए आपको अपने कक्षापथ में जेडीबीसी ड्राइवर डालने की आवश्यकता नहीं है।  
 एक जादू की तरह काम करता है।

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
