You can open a text file and read each line.
  • The BufferedReader represents a text file.
  • You can create BufferedReader from an

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] includes some lines of text.

You can use the try feature in Java 7. This ensures that the file will be closed and disposed of even if the read fails. <def> import java.io.BufferedReader; import java.io.FileReader; public class Demo{

 public static void main(String[] argv)
                       throws Exception{
   try(BufferedReader br =
      new BufferedReader(new FileReader("haggis.txt")))
   {
     for(String line = br.readLine();line!=null;line=br.readLine())
        System.out.println(line);
   }
 }

} </def>
