1byte 출력
1) 콘솔출력
FileOutputStream fos =- new FileOutputStream(FileDescriptor.out);
BufferdOutputStream bos = new BufferdOutputSTream(fos);
DataOutputStream dos = new DataOutputStream(bos);
dos.write(...);

2) 파일 출력용
 File file = new File("파일명");
 FileOutputStream fos = new FileOutputStream(file);
 BufferdOutputStream bos = new BufferdOutputStream(fos);
 DataOutputStream dos = new DateOutputStream(bos);
 dos.write();
 
 3) 네트워크 출력
 Soket soc = new Socket(...);
 BufferdOutputStream bos = new BufferdOutputStream(soc.getOutputStream());
 DataOutputStream dos = new DataOutputStream(bos);
 dos.write(...)

2byte 출력
1) 콘솔 출력

2) 파일 출력
File file = new File("파일명");
FileWirter fw = new FileWriter(file);
BufferdWriter bw = new BufferedWriter(fw);
