file is not being written in scala -

i have file on stored informations, eg.

0,0,0.0,0.00266920744152335,0.0,0.0,0.0 1,0.0,0.0,0.9385656429557993,1.0,0.0,0.0,0 1,0.0,0.0,0.9385656429557993,1.0,0.0,0.0,0 1,0.0,0.0,0.9385656429557993,1.0,0.0,0.0,0 0,0,0.0,0.00266920744152335,0.0,0.0,0.0 ... 

i create 2 more files on want split informations stored in textlines

val textlines = scala.io.source.fromfile("data/sample/textfile.txt") val first = new java.io.printwriter("data/sample/first.txt") val second = new java.io.printwriter("data/sample/second.txt") (line <- textlines.getlines()) {       val row = line.split(",")       if (row(0).equals("0"))         first.println(line)      if (row(0).equals("1"))          second.println(line)     }     first.close()     second.close()     textlines.close() 

the first file written well, second file remains blank.

what's wrong?

i don't know why cleaning project resolve issue.
