java - An alternative to StringBuilders by just using Strings? -


वर्तमान में मेरे पास यह है .... 

  सार्वजनिक स्थैतिक स्ट्रिंग दोहराने वाले (इंट गुणक, स्ट्रिंग पाठ) {स्ट्रिंगबइल्डर दोहराना = नया स्ट्रिंगबइल्डर (); के लिए (int i = 0; i & lt; text.length (); i ++) {for (int j = 0; j & lt; गुणक; j ++) {repeat.append (text.charAt (i)); }} System.out.println ("पत्र दोहराए गए:"); Println ( "-----------"); Println (दोहराने); Println ( "--------------"); वापसी दोहराएं। स्ट्रिंग (); }

मैं इस तरह से कोड चाहूंगा कि अंतिम वक्तव्य जो वर्तमान में "वापसी दोहराएँ। टू स्ट्रिंग ();" पढ़ता है; बस "वापसी मान" करने के लिए मैं यह करने के लिए यह कोड कैसे बना सकता हूँ? क्या ऐसा करने का एक तरीका है कि स्ट्रिंगबइल्डर्स का उपयोग किए बिना और स्ट्रिंग्स का उपयोग कर रहे हैं?

अपने विशेष मामले में आप अपना कोड सरल कर सकते हैं लेकिन ज्यादातर मामलों में, स्ट्रिंगबइल्डर का उपयोग करना बेहतर विकल्प है। और "सीधे स्ट्रिंग का प्रयोग करना" बिल्कुल पसंद नहीं है। 

  सार्वजनिक स्थैतिक स्ट्रिंग दोहराने वाले (इंट गुणक, स्ट्रिंग पाठ) {अंतिम पूर्णांक संख्याएं = पाठ। लम्बाई ( ); चार [] डेटा = नया चार [numChars * गुणक]; के लिए (int i = 0, j = 0, k = गुणक; i & lt; numChars; i ++, j = k, k + = गुणक) arrays.fill (डेटा, j, k, text.charAt (i)); नया स्ट्रिंग (डेटा) लौटाएं; }

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...

scala - Play Framework - how to bind form to a session field -

Is there any way, I can get some parameters from the header, cookies (log in userId in my case) , And then apply it in a form which I know who will deposit the ticket? SupportForm supportForm: form [supportTicket] = form (mapping ("question" -> text, "priority" -> text) (apply support ticket. (HelpText.update) What are the good practices here? What is the call to apply the request, when I can use it (and also a good practice?) Edit An issue, absolutely deceiving anyone if I were to create a hidden area with this value. It could Ript, but the issue may be re-used in any way to verify and return the form, it can not be sure how it ....
