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();
