java - Comparing a char with multiple characters -

- 

  के लिए (int j = 0; j & lt; str.length (); j ++) {if (चार [j] ] == (ए || ई || आई || ओ || यू)) गणना ++; }

मुझे (a || e || i || o || u) का परिणाम पता है एक बूलियन है, इसलिए तुलना नहीं की जा सकती, लेकिन यह कैसे हो सकता है हम कई चरित्र उपस्थिति की जांच करते हैं?

यह वह नहीं कर रहा है जो आप चाहते हैं कृपया एक स्टैक स्विच कथन का प्रयोग करें: 

  के लिए (int j = 0; j & lt; str.length (); j ++) स्विच (str.charAt (j) ) {केस 'ए': केस 'ई': केस 'आई': मामले 'ओ': मामले 'यू': गणना ++; }

या, क्योंकि मैं regex उत्साही हूँ, यहां नियमित अभिव्यक्ति का उपयोग कर एक दृष्टिकोण है! :)

<पूर्व> Matcher matcher = Pattern.compile ("[aeiou]")। मैटचर (str); जबकि (matcher.find ()) गिनती ++;

बाद में इस कोड में एक गलती हुई थी,

Edit: In the socket: The CanReceive () argument was the reason I was checking the input 1 millisecond While stepping into GDB, everything worked out. I have a problem with C sock send () / recv () do nothing if they are in non-debug mode. Even if std :: cout can not return their return value for some reason std :: cout is not working in my method I std: : Cerr can not even make a mistake It does not make sense to check that in GDB, because everything works perfectly as a virus in non-debug mode. C does not. //b - buffer // s - size // sd - socket descriptor int32_t TCP :: reception (char * b, uint32_t s) {error :: critical. SetErrorNumber (error: List :: noor); If (!

GO: Serve static pages -

-
I'm trying to display a static page with Go. Go: Package main import "net / http" function main () {fs: = http.FileServer (http.Dir ("static / house")) Http: .handle ("/", fs) http.ListenAndServe (": 4747", zero)} directory: project / stable home Html edit.html project.go When I run it, the web page displays links to edit.html and home.html instead of displaying a static page from home.html is. What am I doing wrong. Is this the best way to serve files? I know that there are other ways like From the HTML / templates package, but I'm not sure what is the difference between each of these methods and when. Thanks! fancy main () {http.Handle ("/", http.FileServer (Http) .ir ("static")) http.ListenAndServe (": 4747", zero)} You do not need static / home , just Static . and when you do not have index.html in / static , the directory instead Content appears.
