Explanation / Answer

import java.io.File;
import java.util.ArrayList;
import java.util.List;

public class FileSizeDemo {

   public static void main(String[] args) {
       List<String> files = new ArrayList<String>();
       files.add("words.txt");
       files.add("sample.txt");
       for (String filename : files) {
           File file = new File("D:\" + filename);

           if (file.exists()) {

               double bytesoccupied = file.length();
               double kb = (bytesoccupied / 1024);
               double mb = (kb / 1024);
               double gb = (mb / 1024);
               double tb = (gb / 1024);
               double pb = (tb / 1024);
               double exabyte = (pb / 1024);
               double zettab = (exabyte / 1024);
               double yottab = (zettab / 1024);

               System.out.println("the file" + filename + " occupied bytes : "
                       + bytesoccupied);
               System.out.println("kilobytes occupied in memory : " + kb);
               System.out.println("megabytes occupied in memory: " + mb);
               System.out.println("gigabytes occupied in memory: " + gb);
               System.out.println("terabytes occupied in memory: " + tb);
               System.out.println("petabytes occupied in memory: " + pb);
               System.out.println("exabytes occupied in memory: " + exabyte);
               System.out.println("zettabytes occupied in memory : " + zettab);
               System.out.println("yottabytes occupied in memory: " + yottab);
           } else {
               System.out.println("the file in the list not exists!");
           }

       }

   }
