help, again, please, go on, you know you want to.

how do I read the next line rather than repeatedly read the same line in this part of a loop?:

try
{
FileInputStream empStream = new FileInputStream ("employee.dat");
InputStreamReader inemp = new InputStreamReader(empStream);
empReader = new BufferedReader (inemp);
line = empReader.readLine();
StringTokenizer A = new StringTokenizer (line);

for (i=0; i<2; i++)
{
em[i]= A.nextToken();
}
}
