java - Scanner.next returning path of file? -

-

मेरे पास एक स्कैनर है: 

  m = नया स्कैनर (मान। Mazegen.replace ( "\\", "//") + "//maze.txt");

(मान। Mazegen.replace ("\", "//") + "//maze.txt" प्रिंट के रूप में C: // users // myusername // डेस्कटॉप) और जब मैं m.next () का उपयोग करता हूं तो यह C: //users//myusername//Desktop//maze.txt देता है। मुझे कोई जानकारी नहीं है की क्यों...? पूर्ण कोड: 

  सार्वजनिक शून्य खुलाफ़ाइल () {try {if (Values.custom == true & amp; Values.customSolved == false) {m = नया स्कैनर (नई फ़ाइल (मान .MazeFile)); } Else if (Values.customSolved == true || Values.custom == false) {m = नया स्कैनर (मान। Mazegen.replace ("\\", "//") + "//Maze.txt") ; } और {एम = नया स्कैनर (मान.मज़ेज.रेले ("\\", "//") + "//Maze.txt"); }} पकड़ (FileNotFoundException ई) {System.out.println ("फ़ाइल नहीं मिली!"); } यदि (वैल्यूज कूफ्यूम == सत्य & amp; Values.customSolved == गलत) {m.nextLine (); }} Public void readFile () {System.out.println ("अब तक समझे ..."); जबकि (m.hasNext ()) {for (int i = 0; i & lt; Values.x; i ++) {भूलभुलैया [i] = m.next (); Println (भूलभुलैया [i]); } M.nextLine (); }} सार्वजनिक शून्य बंदफ़ाइल () {m.close (); }

(OpenFile, readFile, और closeFile को क्रम में क्रियान्वित किया जाता है)

स्ट्रिंग स्ट्रिंग को स्कैन करता है जिसे आप इसे पास करते हैं, फ़ाइल नहीं। एक फ़ाइल उपयोग को स्कैन करने के लिए नया स्कैनर (नया फ़ाइल ("फ़ाइल के लिए पथ"))

इसके अलावा आपको डबल फ़ॉरवर्ड स्लैश का उपयोग नहीं करना चाहिए।

c++ - C/pp Sockets, recv()/send() works only under gdb -

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. Just change the name of...

I want to use the front and rear camera at the same time in iOS development: when I take a photo back After the camera, the front camera can be opened and another can take a photo.
