You can scan the text line by line and split each line in tokens using String.split() method. This way you know when one line has ended and also have all the tokens on each line:

Scanner sc = new Scanner(input);
while (sc.hasNextLine()){
    String line = sc.nextLine();
    if (line.isEmpty())
        continue;
    // do whatever processing at the end of each line
    String[] tokens = line.split("\\s");
    for (String token : tokens) {
        if (token.isEmpty())
            continue;
        // do whatever processing for each token
    }
}
