public class CopyDirectory{

public static void main(String[] args) throws IOException{

CopyDirectory cd = new CopyDirectory();
BufferedReader in = new BufferedReader
(new InputStreamReader(System.in));
System.out.println("Enter the source directory or file name : ");

String source = in.readLine();

File src = new File(source);

System.out.println("Enter the destination
directory or file name : ");
String destination = in.readLine();

File dst = new File(destination);

cd.copyDirectory(src, dst);

}


public void copyDirectory(File srcPath, File dstPath)
throws IOException{

if (srcPath.isDirectory()){

if (!dstPath.exists()){

dstPath.mkdir();

}


String files[] = srcPath.list();

for(int i = 0; i <>){
copyDirectory(new File(srcPath, files[i]),
new File(dstPath, files[i]));

}

}

else{

if(!srcPath.exists()){

System.out.println("File or directory does not exist.");

System.exit(0);

}

else

{

InputStream in = new FileInputStream(srcPath);
OutputStream out = new FileOutputStream(dstPath);
// Transfer bytes from in to out
byte[] buf = new byte[1024];

int len;

while ((len = in.read(buf)) > 0) {

out.write(buf, 0, len);

}

in.close();

out.close();

}

}

System.out.println("Directory copied.");
