downloading to a certain directory

Hey guys,
I wanna download a file to a certain directory on the computer. I have code that downloads to the same place where it's launched but I want it to download the files do another directory.

(This isnt my code I found it on a tutorial)

Here is the code:
java Syntax (Toggle Plain Text) 
  1. package downloaderPKG;
  2.  
  3. import java.io.*;
  4. import java.net.*;
  5.  
  6. public class FileDownload {
  7. 	public static void download(String address, String localFileName) {
  8. 		OutputStream out = null;
  9. 		URLConnection conn = null;
  10. 		InputStream  in = null;
  11. 		try {
  12. 			URL url = new URL(address);
  13. 			out = new BufferedOutputStream(
  14. 				new FileOutputStream(localFileName));
  15. 			conn = url.openConnection();
  16. 			in = conn.getInputStream();
  17. 			byte[] buffer = new byte[1024];
  18. 			int numRead;
  19. 			long numWritten = 0;
  20. 			while ((numRead = in.read(buffer)) != -1) {
  21. 				out.write(buffer, 0, numRead);
  22. 				numWritten += numRead;
  23. 			}
  24. 			System.out.println(localFileName + "\t" + numWritten);
  25. 		} catch (Exception exception) {
  26. 			exception.printStackTrace();
  27. 		} finally {
  28. 			try {
  29. 				if (in != null) {
  30. 					in.close();
  31. 				}
  32. 				if (out != null) {
  33. 					out.close();
  34. 				}
  35. 			} catch (IOException ioe) {
  36. 			}
  37. 		}
  38. 	}
  39.  
  40. 	public static void download(String address) {
  41. 		int lastSlashIndex = address.lastIndexOf('/');
  42. 		if (lastSlashIndex >= 0 &&
  43. 		    lastSlashIndex < address.length() - 1) {
  44. 			download(address, address.substring(lastSlashIndex + 1));
  45. 		} else {
  46. 			System.err.println("Could not figure out local file name for " +
  47. 				address);
  48. 		}
  49. 	}
  50. }
History will be kind to me for I intend to write it.

Just specify the entire path where you want to store file as localFileName.

Okay so I modified new FileOutputStream("C:\\"+localFileName)); now here is my code:
java Syntax (Toggle Plain Text) 
  1. package downloaderPKG;
  2.  
  3. import java.io.*;
  4. import java.net.*;
  5.  
  6. public class FileDownload {
  7. 	public static void download(String address, String localFileName) {
  8. 		OutputStream out = null;
  9. 		URLConnection conn = null;
  10. 		InputStream  in = null;
  11. 		try {
  12. 			URL url = new URL(address);
  13. 			out = new BufferedOutputStream(
  14. 				new FileOutputStream("C:\\"+localFileName));
  15. 			conn = url.openConnection();
  16. 			in = conn.getInputStream();
  17. 			byte[] buffer = new byte[1024];
  18. 			int numRead;
  19. 			long numWritten = 0;
  20. 			while ((numRead = in.read(buffer)) != -1) {
  21. 				out.write(buffer, 0, numRead);
  22. 				numWritten += numRead;
  23. 			}
  24. 			System.out.println(localFileName + "\t" + numWritten);
  25. 		} catch (Exception exception) {
  26. 			exception.printStackTrace();
  27. 		} finally {
  28. 			try {
  29. 				if (in != null) {
  30. 					in.close();
  31. 				}
  32. 				if (out != null) {
  33. 					out.close();
  34. 				}
  35. 			} catch (IOException ioe) {
  36. 			}
  37. 		}
  38. 	}
  39.  
  40. 	public static void download(String address) {
  41. 		int lastSlashIndex = address.lastIndexOf('/');
  42. 		if (lastSlashIndex >= 0 &&
  43. 		    lastSlashIndex < address.length() - 1) {
  44. 			download(address, address.substring(lastSlashIndex + 1));
  45. 		} else {
  46. 			System.err.println("Could not figure out local file name for " +
  47. 				address);
  48. 		}
  49. 	}
  50. }

Here is my error:
Java Syntax (Toggle Plain Text) 
  1. java.io.FileNotFoundException: C:\application.jar (Access is denied)
  2. 	at java.io.FileOutputStream.open(Native Method)
  3. 	at java.io.FileOutputStream.<init>(Unknown Source)
  4. 	at java.io.FileOutputStream.<init>(Unknown Source)
  5. 	at downloaderPKG.FileDownload.download(FileDownload.java:14)
  6. 	at MainClass.main(MainClass.java:11)
History will be kind to me for I intend to write it.
