reader.readLine() not working as expected

import java.io.BufferedReader;

public class CSS_Test_4_10_2024 {

            String sentence;

I have a sentences.txt with 60 lines of text. I wanted it to print something along the lines of: <div class="text" style="top: [THIS STARTS FROM 5 AND INCREMENTS BY 5, AND FOR EACH THREE INCREMENTS, THE INCREMENT DECREASES BY 1]ex;">[SENTENCE GOES HERE] [HOW MANY TIMES THIS HAS RUN GOES HERE]</div> As an example, the first few lines should show: <div class="text" style="top: 5ex;"> Lorem ipsum... 1</div> <div class="text" style="top: 10ex;"> dolor sit amet... 2</div> <div class="text" style="top: 15ex;"> adipscicing ameold.. 3</div> <div class="text" style="top: 19ex;"> molor alor... 4</div> ... <div class="text" style="top: ??ex;"> blablabla... ?<60</div> To my confusion, the result looks like: ... <div class="text" style="top: 2694ex;">Curabitur rutrum... 899</div> <div class="text" style="top: 2695ex;">Curabitur rutrum... 900</div> Not only did reader.readLine() seem to read the same line (not shown, but it does this every 16~ times), and the top:??ex and number at the end seems to vastly exceed what I thought should have resulted from the for loop
