You can open a text file and read each line.

Reading lines

  • The BufferedReader represents a text file.
  • You can create BufferedReader from a

FileReader.

  • The while condition (s=fh.readLine())!=null does two

things, it assigns the string s and it checks for null.

The text file [../haggis.txt haggis.txt] includes some lines of text.
