public class Example {
     public Example() throws IOException {
          String lines[] = readReverse("example.txt");
          // print the lines
          for (int j = 0;j < lines.length;j++) {
               System.out.println(lines[j]);
     protected String[] readReverse(String file) throws IOException {
          BufferedReader b = new BufferedReader(new InputStreamReader(new FileInputStream(file)));
          ArrayList al = new ArrayList(0);
          String s = "";
          while ((s = b.readLine()) != null) {
               al.add(s);
          // reverse it
          String lines[] = new String[al.size()];
          for (int j = 0;j < lines.length;j++) {
               lines[j] = (String)al.get(al.size()-(j+1));
          return lines;
     public static void main(String[] args) {
          try {
               new Example();
          catch (IOException e) {
               e.printStackTrace();
