java copying a file results in access denied exception

[Valemore]

Hi, newbie here, first time posting
I decided to start playing arround with the fileinputstreams and outputstreams and wrote a program that copies a file to another folder, but it always throws a FileNotFound: access denied exception.

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.Scanner;


public class filecopy {

	public static void main(String[] args) throws IOException {
		   	Scanner in=new Scanner(System.in);
			System.out.println("So..i've heard you like to copy files?");
		   	System.out.println("specify source file path");
			String source=in.next();
			System.out.println("specify destination file path");
			String target=in.next();
		   	InputStream inn = new FileInputStream(source);
	                OutputStream out = new FileOutputStream(target);
	                byte[] buf = new byte[2048];
	                int len;
	                while((len=inn.read(buf))>0){
	        	       out.write(buf, 0, len);
	                }
	                inn.close();
	                out.close();

	}

}

i've checked the file permissions and apparently I have full control over it
i am the system admin and i've tried coyping to and from different folders.
I am using windows 7

here's the error.

Exception in thread "main" java.io.FileNotFoundException: C: (Access is denied)
	at java.io.FileOutputStream.open(Native Method)
	at java.io.FileOutputStream.<init>(Unknown Source)
	at java.io.FileOutputStream.<init>(Unknown Source)
	at filecopy.main(filecopy.java:20)

I appreciate the help.

Many thanks in advance.

I think you are supposed to write instead of

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

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

[Valemore]

attempted that.. exception persists :C
thanks for the help

When you specify a directory, specify the directory up to the name i.e.

//correct directory name
String dir = "C:/Program Files/MyProgram"

//throws FileNotFound ex
String dir = "C:/Program Files/MyProgram/"

so make sure the path you enter doesn't end with a '/' otherwise it will look for a file or folder named "" within that path

[ozzyman]

As for the access denied, make sure the folder/file is not Read-Only first.

ahh thanks, im so dumb lol
I had the destination folder path end with the folder name and didn't specify the file.
for example i had
source= C:\Myfolder\file.txt
target=C:\Myfolder

here's the error.

Exception in thread "main" java.io.FileNotFoundException: C: (Access is denied)

Your program is trying to open "C:" which isn't a regular file, it is your entire hard disk.

kind regards,

Jos

That is not true: the FileNotFoundException class extends the IOException class so only the latter needs to be specified in the throws clause.
