i have bit of code like if (system.io.file.exists(newfilepath)) { string suffix = (datetime.now.ticks / timespan.tickspermillisecond).tostring(); newfilepath += suffix; but realized it's incorrect because meant put suffix before extension part of file name (if there 1 @ all). example: c://somefolder/someotherfolder/somepic.jpg ---> c://somefolder/someotherfolder/somepic0123913123194.jpg is there 1-line way this, instead of me spending time handrolling procedure lastindexof , insert , etc. a simple 1 liner be: newfilepath = string.format("{0}{1}{2}", path.getfilenamewithoutextension(newfilepath), suffix, path.getextension(newfilepath)); edit: or preserve directory too: newfilepath = string.format("{0}{1}{2}{3}", path.getdirectoryname(newfilepath), path.getfilenamewith...

i using spark streaming (coding in java), , want understand how can make algorithm following problem. relatively new @ map-reduce , need assistance in designing algorithm. here problem in details. problem details input: initial input of text is: (pattern),(timestamp, message) (3)(12/5/2014 01:00:01, message) where 3 pattern type i have converted dstream key=p1,p2, p1 , p2 pattern classes input line, , value = pattern, input, timestamp. hence each tuple of dstream follows: template: (p1,p2),(pattern_id, timestamp, string) example: (3,4),(3, 12/5/2014 01:00:01, message) here 3 , 4 pattern types paired together. i have model each pair has time difference associated it. example, model in hashmap key-values : template: (p1,p2)(time difference) example: (3,4)(2:20) where time difference in model 2:20, , if have 2 messages of pattern of type 3 , 4 respectively in stream, program should output anomaly if difference between 2 mes...
