これを試してみませんか:
BufferedReader bufferedReader = null;
try {
bufferedReader = new BufferedReader(new FileReader("testing.txt"));
String line = bufferedReader.readLine();
while(line != null){
byte[] b = line.getBytes();
}
} finally {
if(bufferedReader!=null){
bufferedReader.close();
}
}
また
FileInputStream in = null;
BufferedReader bufferedReader = null;
try {
bufferedReader = new BufferedReader(new FileReader("xanadu.txt"));
String line = bufferedReader.readLine();
while(line != null){
//read your line
}
in = new FileInputStream("xanadu.txt");
int c;
while ((c = in.read()) != -1) {
//read your bytes (c)
}
} finally {
if (in != null) {
in.close();
}
if(bufferedReader!=null){
bufferedReader.close();
}
}
