java - How to get FolderName and FileName from the DirectoryPath -


i have directorypath "data/data/in.com.jotsmart/app_custom/foldername/filename" stored string in arraylist

like 

arraylist<string> a; a.add("data/data/in.com.jotsmart/app_custom/page01/note01.png");

now path want page01 seperate string , note01 seperate string , stored 2 string variable. tried lot, not able result. if 1 knows me solve out.

f.getparent()

returns pathname string of abstract pathname's parent, or null if pathname not name parent directory.

for example 

 file f = new file("/home/jigar/desktop/1.txt"); system.out.println(f.getparent());// /home/jigar/desktop system.out.println(f.getname()); //1.txt

update: (based on update in question)

if data/data/in.com.jotsmart/app_custom/page01/note01.png valid representation of file in file system then

for(string filenamestr: fileslist){ file file = new file(filenamestr); string dir = file.getparent().substring(file.getparent().lastindexof(file.separator) + 1);//page01 string filename = f.getname(); if(filename.indexof(".")!=-1){ filename = filename.substring(0,filename.lastindexof(".")); } }

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
