Who to access other remote machine folder from java program which is in another remot

According to my requirment:
I have developed a code which get all the Folders and files path and there size respectivelyfor that particular Remote machine. Now i want to access other remote machine from the same piece of code.

Or I can say suppose I created one HTML page in which i gave 5 Remote machine name and a submit button.
So when i checked all the checkbox and submit the button it sgould show all the folder anf file names with size for that oarticular machines
Here i am pasting my code:

Code:

---

import java.io.File;
import java.io.OutputStreamWriter;
import java.text.DecimalFormat;
import java.text.NumberFormat;


public class  GetFolderSize
{
        long totalsize=0;

        static GetFolderSize fg=new GetFolderSize();
        public static void main(String args [])
        {
               
                try
                {
                        File file = new File("D:/Projects");
                        File[] listOfFiles = file.listFiles();
                long size = 0;
               
                for (int i = 0; i < listOfFiles.length; i++)
                {
                        if(listOfFiles[i].isFile())
                        {
                            System.out.println("File Names: " + listOfFiles[i].getName());
                            size = file.length();
                    }   
                else if(listOfFiles[i].isDirectory())
                {
                        System.out.println("Folder Names:" + listOfFiles[i].getName());
                }
                        File[] subFiles = file.listFiles();

                        for (File file1 : subFiles)
                        {
                                if (file1.isFile())
                                {
                                       
                                        size =fg.getFileSize(file1);
                            }
                                else
                                {
                                         
                                }
                        }
                }
               
            fg.sizecal(size, file);
                }
                catch (Exception e)
                {
                        System.out.print(e.getMessage());
                }
        }

                public long getFileSize(File file )
                  {       
                        long fileSizeByte =0;
                       
                  if(file.isFile())
                  {
                          fileSizeByte=file.length();
                          fg.sizecal(fileSizeByte,file);
                          totalsize=totalsize+fileSizeByte;
                }
                  else if(file.isDirectory())
                  {
                          fileSizeByte=file.length();
                          fg.sizecal(fileSizeByte,file);
                          totalsize=totalsize+fileSizeByte;
                  }
                   
                        return totalsize;
                }
               
                public void sizecal(long fileSizeByte,File file)
                {
                        DecimalFormat fmt =new DecimalFormat("#.##");
                          Double fileSizeKB=Double.valueOf(fmt.format(1024));           
                          Double fileSizeMB=Double.valueOf(fmt.format(1024*1024));           
                          Double fileSizeGB=Double.valueOf(fmt.format(1024*1024*1024));
                       
                                if(fileSizeByte>fileSizeGB)
                                  {
                                    System.out.println(file.getAbsolutePath()+": size :"+fileSizeByte/ 103741824+" GB" );
                                  }
                                  else if(fileSizeByte>fileSizeMB)
                                  {
                                    System.out.println(file.getAbsolutePath()+": size :"+fileSizeByte/1048576+" MB" );
                                  }
                                  else if(fileSizeByte>fileSizeKB)

                                  }
                                  else
                                  {

                                  }

How do you plan to access the remote machine? Using classes like Socket or URLConnnection?

Hi Norm,

Sorry for late response.
URL connection will be suitable for my requirment.

THanks,
Pallavi

And one more thing the remote which i am plaaning to access are not having Java installed.

The remote machines will need some software that your program can communicate with. Do you know what that will be?
Some kind of server to talk to and make requests of.

yes they are connected to server and they make request to rsq38pelgen.

Can you explain what software is on the remote machines and how your software will communicate with the remote machines?
