Scala - proper way to print a string to file -

what proper way print string - , string - file? when try standard way known me, i.e:

def printtofile(o:object,n:string) = try{   val pathtooutput = "..\\some\\parent\\directory\\"   val path = paths.get(pathtooutput + n)    val b = new bytearrayoutputstream()   val os = new objectoutputstream(b)   os.writeobject(o)    files.write(path, b.tobytearray,     standardopenoption.create,     standardopenoption.truncate_existing) }catch{   case _:exception => println("failed write") } 

it seems prepend

’ nul enqtstxt

where part after enqt seems vary. (doesn't matter if declare oan object or string.)

this annoying because want print couple of .dot-strings (graphviz) in order batch-process resulting .dot-files .pdf-files. prepended nonsense, however, forces me open each .dot-file , remove manually - kind of defeats purpose of batch-processing them.

this has nothing scala specifically, it's way java standard library works. when writeobject writing serialized representation of object, bunch of additional bytes jvm can use re-create object. if know object string, strong-type (i.e., use printtofile(o:string,n:string) , can use files.write(path, o.getbytes, .... otherwise use o.tostring.getbytes.
