Code :

import java.io.*;
import java. util. Scanner;

public class movieList {
       
   /**
   * Opens and reads a file,
   */
   public static int findMovieList(File file, int year1, int year2)
   throws IOException
   {
      BufferedReader reader = new BufferedReader(new FileReader(file));
      String line;                    //Extract lines from the db.txt
      int match = 0;                 //Match counter..
      StringBuilder sb = new StringBuilder();
      System.out.print("\n Movies with short names that were released between " + year1 + " and "+ year2 + ": \n");
      while ((line = reader.readLine()) != null)
      {
        sb.append(line + "\n");
      
        String[] values = line.split(";");        //Splitting Data from the file..
        int year = Integer.parseInt(values[0].trim());   //Storing the year
        if (year ==(year1) || year ==(year2))        //Checking the year1 and year2
           if(values[2].length() < 6) {             //Checking length of the movie < 6
               System.out.println((values[2]));     //Print only the year1 & yer2 movie's names
               match = match + 1;                 //Counts total number of matches:
           }
      }

      reader.close();           //Close the reader..
      return match;   
   }
  
   public static void main(String[] args)throws Exception
      {
      // We need to provide file path as the parameter:
      // double backquote is to avoid compiler interpret words
      // like \test as \t (ie. as a escape sequence)
  
      File file = new File("/home/Desktop/java/db.txt");         //Please provide your path to the file...
      System. out. print( "Movie search by year range.\n\nEnter two years : ");
  
      int year1;
      int year2;
  
      Scanner sc = new Scanner(System.in).useDelimiter("\\s");
      year1 = sc.nextInt(); // It will not leave until the user enters data.
      year2 = sc.nextInt(); // We can read specific data.
  
      int match = findMovieList(file, year1,year2); //Function call to find movies..
      if (match == 0 )
          System.out.print("\n No matching movies found! ");
      else
          System.out.println("\n Number of matches: " + match);
      sc.close();
      }
}
  

input db.txt: (Sample for this program)
