java - What does each element do ("(.)\\1{1,}", "$1") in this code? -

- 

  आयात करें java.util.Scanner; पब्लिक क्लास रेडिएजेज {सार्वजनिक स्टेटिक व्हाइड मेन (स्ट्रिंग एजीआर []) {स्कैनर स्कैन = न्यू स्कैनर (सिस्टम।); System.out.println ("इनपुट पाठ!"); स्ट्रिंग teksts = scan.nextLine (); System.out.println ("परिवर्तन के बाद पाठ!"); System.out.println (teksts.replaceAll ("(।) \\ 1 {1,}", "$ 1")); }}

यह समान अक्षर के अनुक्रमों से मेल खाता है और उन्हें केवल एक ही घटना में गिर जाता है। / P>

उदाहरण: "aaaaabcccdd" -> "abcd"

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
