Answer 1

You can read text from a file one line at a time and then do whatever you want to with that line, print it, compare it, etc...

// Construct a BufferedReader object from the input file
BufferedReader r = new BufferedReader(new FileReader("employeeData.txt"));
int i = 1;
try {

    // "Prime" the while loop        
    String line = r.readLine();
    while (line != null) {

        // Print a single line of input file to console
        System.out.print("Line "+i+": "+line); 

        // Prepare for next loop iteration
        line = r.readLine();
        i++;
    }
} finally {
    // Free up file descriptor resources
    r.close();
}

// Remember the next available employee number in a one-up scheme
int nextEmployeeId = i;
