awt - How can i get the width and height of an image in java using intelij idea? -


मैं निम्नलिखित जावा वर्ग 

  सार्वजनिक वर्ग मुख्य {निजी स्थिर BufferedImage छवि लिखा है; निजी स्थिर स्ट्रिंग srcImageName = "HeatMap.png"; सार्वजनिक स्थिर शून्य मुख्य (स्ट्रिंग [] आर्ग्स) {initializeImage (); Println (image.getWidth ()); } निजी स्थिर शून्य प्रारंभिक इमेज () {image = null; कोशिश {image = imageIO.read (नई फ़ाइल (srcImageName)); } पकड़ (IOException ई) {System.out.println ("छवि नहीं पढ़ा जा सकता है" + srcImageName); //e.printStackTrace (); }}}   
 अब मेरी फ़ाइल संरचना है, ताकि जैसे:  
     
  •  main.java फ़ाइल  
  •  HeatMap.png फ़ाइल < / Li>  
     ये दोनों एक ही फ़ोल्डर में हैं  
     छवि HeatMap.png पढ़ा नहीं जा सकता  
     यह मुझसे कहता है कि वह छवि है जो मैं समझ नहीं नहीं देखता: समस्या यह है कि जब मैं कार्यक्रम चलाने मैं निम्नलिखित प्रतिक्रिया मिल है क्यों  
     कृपया मदद करें।   
     
     
     ये दोनों एक ही फ़ोल्डर में हैं कोशिश करें  <पूर्व>  BufferedImage image = ImageIOreadread (getClass ()। GetResourceAsStream ("HeatMap.png")); Int w = image.getWidth (); Int h = image.getHeight ();   
     
     आप अन्य विकल्पों को भी आज़मा सकते हैं। टिप्पणियां पढ़ें।  
      // एक ही पैकेज से पढ़ें imageIO.read (getClass ()। GetResourceAsStream ("c.png")); // पूर्ण पथ से पढ़ें imageIO.read (नई फ़ाइल ("ई: \\ सॉफ़्टवेयर \\ ट्रेनपिस \ \ res \\ ड्रॉएबल \\ c.png")); // अपनी परियोजना imageIO.read (नया फ़ाइल ("छवियों \\ c.jpg")) में स्रोत के चित्र फ़ोल्डर से समानांतर पढ़ें;)

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...
