How can I initiate all the files in a directory as instances?

Sorry, I mean all the memory spaces used by all the files in a directory.

I have written a simple program. Is this feasible to retrieve what I want?

import java.io.*;

public class ShowFileSize

{

public static void main (String[]args)

{

File testFile = new File("***a path of a directory*****");

File [] testFiles = testFile.listFiles();

long fileSize = 0;

for (int i=0;i<testFiles.length;i++)

{

if (testFiles[i].isDirectory())

fileSize = getDirectorySize(testFiles[i].getPath());

else if (testFiles[i].isFile())

fileSize += testFiles[i].length()/1024;

}

System.out.println("Size of the directory: "+fileSize+"KB");

}

public static long getDirectorySize(String path)

{

long fileSize = 0;

File directory = new File(path);

File [] objInDirectory = directory.listFiles();

for (int i=0;i<objInDirectory.length;i++)

{

if (objInDirectory[i].isDirectory())

fileSize += getDirectorySize(objInDirectory[i].getPath());

else if (objInDirectory[i].isFile())

fileSize += objInDirectory[i].length()/1024;

}

return fileSize;

}

}

Modified version according to your advices:

import java.io.*;

public class ShowFileSize

{

private static long sizeOfDirectory = 0;

public static void main (String[]args)

{

getDirectorySize("****path of directory***");

System.out.println("Size of the directory: "+sizeOfDirectory+"KB");

}

public static long getDirectorySize(String path)

{

long fileSize = 0;

File directory = new File(path);

File [] objInDirectory = directory.listFiles();

for (int i=0;i<objInDirectory.length;i++)

{

if (objInDirectory[i].isDirectory())

sizeOfDirectory += getDirectorySize(objInDirectory[i].getPath());

else if (objInDirectory[i].isFile())

fileSize += objInDirectory[i].length()/1024;

}

return fileSize;

}

}

The result is much more close to the actual value. But why is there a difference?

My directory size is 187MB, but the result is 167MB.>
