java - Missing return statement error in method -

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

      आयात करें java util.Scanner; सार्वजनिक कक्षा मुख्य {सार्वजनिक स्थैतिक स्ट्रिंग डस्टफ़ास्ट (इंट संख्या) {// आपका कोड यहाँ (इंट आई = 1; आई & lt; 5; i ++) {if (i == संख्या) {स्ट्रिंग str = String.valueOf (i) ; वापसी str; } और अगर (i & gt; 4) {वापसी "बहुत बड़ा"; } और अगर (i & lt; 1) {वापसी "बहुत छोटा"; }}} सार्वजनिक स्थिर शून्य मुख्य (स्ट्रिंग [] आर्ग्स) {स्कैनर = नए स्कैनर (System.in); int n = in.nextInt (); के लिए (इंट आई = 0; आई & lt; n; i ++) {int a = in.nextInt (); System.out.println (डस्टफ (ए)); }}   
    }  
     जब मैं इस कोड को चलाता हूं, तो मुझे निम्न त्रुटि मिलती है:  
      मेन.जावाआडर: त्रुटि  
     इस समस्या को हल करने के लिए मुझे क्या करना चाहिए?  
     निम्न शर्त देखें: 1 से 4 (समावेशी) की संख्या को देखते हुए , संख्या के एक शब्द प्रतिनिधित्व को वापस। उदाहरण के लिए, 2 दिया, दो वापसी करें यदि संख्या 4 से अधिक है, तो वाक्यांश बहुत बड़ी लौटें। यदि संख्या 1 से कम है, तो वाक्यांश बहुत छोटा लौटें।   
     
     
      डस्टफ ()  पद्धति सशर्त रिटर्न स्टेटमेंट हैं (वर्तमान में  if-else  या  for  loop)। विधि के अंत में आपको एक डिफ़ॉल्ट  return  की आवश्यकता है, जिससे कि विधि को कुछ कंडीशनिंग ब्लॉक निष्पादित होने पर कुछ देता है।  
      सार्वजनिक स्थिर स्ट्रिंग DoStuff (int num) {// आपका कोड यहाँ (इंट I = 1; i & lt; 5; i ++) {if (i == num) {स्ट्रिंग str = String.valueOf (i); वापसी str; } और अगर (i & gt; 4) {वापसी "बहुत बड़ा"; } और अगर (i & lt; 1) {वापसी "बहुत छोटा"; }} वापसी नल; // अगर डिफ़ॉल्ट ब्लॉक को निष्पादित नहीं किया जाता है तो डिफ़ॉल्ट वापसी। }

c++ - Cmake produces file extensions in static library archives -

I have recently switched to autotools to cement, since the limiter cross platform is better for development and what I saw When I build a stable library of my C ++ code, all the files inside .cpp.o is a suffix ar income tax PA8 / libgenericTZR.a genericTZR.cpp.o I have seen other libraries made by other tools and they do not do it, I'm not sure this is the realm And there is a bad thing, but how can I create static libraries without cpp file extension? This is my CMake file add_executable (PA8 ISP_Charges.cpp genericTZR.cpp genericTZR.h) set (LIBSRC genericTZR.c genericTZR.h) add_library (genericTZR shared $ {LIBSRC}) add_library (genericTZR shared $$ TARGET_OBJECTS: myObjects & gt;) install add_library (Generic TZR-static static $ {LIBSRC}) set_target_properties (Generic TZR-Static Properties OUTPUT_NAME $ install (TARGETS PA8 DESTINATION BIN) TARGETS GENICTZR GENERICTZR-STATIC DESTINATION lib) Installed (files "$ {PROJECT_BINARY_DIR} /PA8/genericTZR.h...

c# - XML - Serialize class - Some questions -

-
I have the idea of ​​serializing the properties of a class in an XML-file and then uploading this file to the server The reason for this is that I want to download this file again and read the serialized content. Then this kind of structure: file exists (myfile.xml) - & gt; Serialize the file in data from class (myclass.cs) - & gt; Upload file. Now the content may look something like this: Now the problem is, I do not know how to walk. I want the new data to be serialed in the next way, but it should be linked to that XML-file, not a new one. So I download this file and then I serialize the new data as an attachment so that it will look like this: And it should be repeated many times as I want: download file, serial new data and attach it together, then upload it again. Now, the second issue is, I want to read it. I also use XML-class for this. For the type of ultimate type, the data should be serialized, I set the square in which the assets are. But now,...
