I have simple class to read from text file.  the clas work ok, but the "deprecation" warrning is bugging me :(

C:\>javac FileInput.java -Xlint
FileInput.java:29: warning: [deprecation] readLine() in java.io.DataInputStream
has been deprecated
        System.out.println(dis.readLine());
                              ^
1 warning

C:\>javac FileInput.java
Note: FileInput.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

here is the class:
import java.io.File;
import java.io.FileNotFoundException;
import java.io.IOException;

public class FileInput {

  public static void main(String[] args) {
    File file = new File("C:\\que.sql");    
    try {
      fis = new File(file);
        
        BufferedReader in = new BufferedReader(new InputStreamReader(fis));
                
      while (in.available() != 0) {

     
        System.out.println(in.readLine());
      }

      fis.close();
     
    } catch (FileNotFoundException e) {
      e.printStackTrace();
    } catch (IOException e) {
      e.printStackTrace();
    }
  }
}

The class you posted doesn't use DataInputStream. It does use BufferedReader, which is the way to get rid of the deprec.

Yes you're not even importing DataInputStream.

Moreover, you are not even importing the other classes like BufferedReader, InputStreamReader or IOException or the entire io package. So you have posted the wrong code - pls post the correct one.
