Drag and drop from the options below to read and print the content of the file a.txt, and then close it.
try {
   File f = new File("a.txt");
  Scanner sc = new (f);
  while (sc.hasNext()) {
      String a = .next();
      String b = sc.();
      System.out.println(a + " " + b);
  } 
  sc.();
} 
catch (Exception e) {
   System.out.println("Error");
}
