  • We can read java file using buffered reader class in java
  • We need to import java.io.BufferedReader in order to read java text file.

  19. e.printStackTrace();
  20. } finally {
  21.     try {
  22. if (breader != null)
  23. breader.close();
  24.      } catch (IOException ex) {
  25. ex.printStackTrace();
