What you want is to use a BufferedReader
instance to read from the file, and parse each line that you get from it.
For example:
try {
BufferedReader reader = new BufferedReader(new FileReader("filename"));
String line;
while ((line = reader.readLine()) != null) {
// parse your line here.
}
reader.close(); // don't forget to close the buffered reader
} catch (IOException e) {
// exception handling here
}
