java - write to file - which way is cleaner? -

i using java.io.printwriter write text text file. wondering if better build in variable need write , give once

printwriter out = new printwriter(outputfile); out.printf("%s", myvariablewithalltext); 

or if can call n times printwriter write block of text in for loop.

it works in either way , there no more code, wondering better.

in cases it's better write in stream. main reason variable might take memory, stream automatically flush it's content. writing text variable manual buffering. , better way use appropriate buffering stream/writer. in case can use java.io.bufferedwriter. so

bufferedwriter out = new bufferedwriter(new printwriter("file.txt")); 

or, if prefer printwriter interface, can this

printwriter out = new printwriter(new bufferedwriter(new filewriter("file.txt")));
