To read lines from a text file, you can use this (uses try-with-resources):

String line;

try (
    InputStream fis = new FileInputStream("the_file_name");
    InputStreamReader isr = new InputStreamReader(fis, Charset.forName("UTF-8"));
    BufferedReader br = new BufferedReader(isr);
) {
    while ((line = br.readLine()) != null) {
        // Do your thing with line
    }
}

More compact, less-readable version of the same thing:

String line;

try (BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("the_file_name"), Charset.forName("UTF-8")))) {
    while ((line = br.readLine()) != null) {
        // Do your thing with line
    }
}

To chunk a line into individual words, you can use String.split:

while ((line = br.readLine()) != null) {
    String[] words = line.split(" ");
    // Now you have a String array containing each word in the current line
}
