Depending on your needs, either:

  BufferedReader reader = new BufferedReader(new FileReader(...));
  for (;;) {
     String line = reader.readLine();
     if (line == null) break;
     ...
  }
  reader.close();

or

  Scanner scanner = new Scanner(...);
  while (scanner.hasNext()) {
     int i = scanner.nextInt(); // or whatever
     ...
  }
  scanner.close();

Or you could use the java.nio package and open a channel to read into a
buffer, probably a CharBuffer but needs vary.

Andrew had the best suggestion: study the I/O (and, I venture to say also the
NIO) tutorials.

Standard sources like these tutorials are likeliest to have been proofread, to
contain examples you can use, to be (relatively) free of wrong-headedness and
the arrogant presumption that the respondent is competent, and to avoid other
ills that might beset the Usenet querent.
