Limiting file size creation with java -

im trying limit size creation of 1 file in java app. made sample code declare 1 variable lenght of 32 bytes, start writeonfile method looping until 32 bytes. problem is, doesnt matter value set set on file_size (higher or lower) download file coming 400kb - means code working since original file 200mb has logic mistake. there way this? cos based myself on post how limit file size in java , until found nothing better

i wondering if has bufferedwriter...

thanks in advance help

public static final byte file_size = 32;      private static void writeonfile(bufferedwriter writer, string crawlingnode){                 try {                    while(file.length()<file_size){                      writer.write(crawlingnode);                     system.out.println(file.length());                    }             } catch (ioexception e) {                  joptionpane.showmessagedialog(null, "failed write url node");                     e.printstacktrace();                         }             } 

i tried around little bit , write files 32 bytes large limiting bufferedwriter's write-method directly:

        writer.write(crawlingnode, 0, 32); 

with call, first 32 chars written file. encoding utf-8, means every char occupies 1 byte, size of output file 32 bytes. writing 16 chars resulted in file of 16 bytes , forth.

so maybe use without implementing other big stuff.

edit:

if string has less characters 32, use following call:

writer.write(crawlingnode, 0, crawlingnode.length);
