    copied!<p>I'm working at a small office,I have an application,it's generate a big text file with 14000 lines;</p> <p>after each generate i must filter it and it's really boring;</p> <p>I wanna write an application with java till I'll can handle it as soon as possible.</p> <p>Please help me; I wrote an application with scanner (Of course with help :) ) but it's not good becase it was very slow;</p> <p>For example it's my file :</p> <pre><code>SET CELL:NAME=CELL:0,CELLID=3; SET LSCID:NAME=LSC:0,NETITYPE=MDCS,T32=5,EACT=FILTER-NOFILTER-MINR-FILTER-NOFILTER,ENSUP=GV2&amp;NCR,MINCELL=6,MSV=PFR,OVLHR=9500,OTHR=80,BVLH=TRUE,CELLID=3,BTLH=TRUE,MSLH=TRUE,EIHO=DISABLED,ENCHO=ENABLED,NARD=NAP_STLP,AMH=ENABLED(3)-ENABLED(6)-ENABLED(9) </code></pre> <p>and I want this output (filter :)</p> <pre><code>CELLID : 3 ENSUP : GV2&amp;NCR ENCHO : ENABLED MSLH : TRUE ------------------------ Count of CELLID : 2 </code></pre> <p>which solution is the best and the fastest than the other ? </p> <p>it's my source code :</p> <pre><code>public static void main(String[] args) throws FileNotFoundException { Scanner scanner = new Scanner(new File("i:\\1\\2.txt")); scanner.useDelimiter(";|,"); Pattern words = Pattern.compile("(CELLID=|ENSUP=|ENCHO=)"); while (scanner.hasNextLine()) { String key = scanner.findInLine(words); while (key != null) { String value = scanner.next(); if (key.equals("CELLID=")) System.out.print("CELLID:" + value+"\n"); //continue with else ifs for other keys else if (key.equals("ENSUP=")) System.out.print("ENSUP:" + value+"\n"); else if (key.equals("ENCHO=")) System.out.print("ENCHO:" + value+"\n"); key = scanner.findInLine(words); } scanner.nextLine(); } } </code></pre> <p>Thank you very much indeed ...</p>
