Java. Compare two objects values in LinkedList -

  सार्वजनिक वर्ग के छात्र {सार्वजनिक स्ट्रिंग का नाम, उपनाम; Int indexnr; विद्यार्थी (स्ट्रिंग का नाम, स्ट्रिंग उपनाम, इंट इंडेक्सर) {this.name = name; This.surname = surname; This.indexnr = indexnr; }

मैंने दो लिंक्ड सूची बनायी है: list1 और list2 और दोनों सूचियों में 5 छात्र शामिल हैं I मेरा मिशन तीसरी सूची - सूची 3 बना रहा है, जो इन छात्रों को निम्नांक से अधिक तक इंडेक्स-संख्याओं के अनुसार क्रमबद्ध करते हैं। कोई मेरी मदद कर सकता है?

सबसे पहले, लागू करता है Comparable & lt; छात्र & gt; क्लास हेडर और compareTo () विधि को छात्र वर्ग के लिए: 

  @Override सार्वजनिक int तुलना करने के लिए (छात्र अन्य) {return Integer.valueOf (this.indexnr) .compareTo (other.indexnr); }

फिर, अपनी सूची को सॉर्ट करें: 

  सूची & lt; छात्र & gt; List3 = ...; // सूची भरने के लिए कुछ तर्क संग्रह। सूची (list3);

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job.

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
