How to copy file in java

Question

Im trying to copy a file in java and move it to a new folder. This is the code i HAve been using but I always get this error "(Access is denied) in the specified directory". Is there a way i can fix this or a better way to copy the files? thanks

try{
          File f1 = new File(fpath);
          File f2 = new File("C:/users/peter/documents/foldertest2/hats");
          InputStream in = new FileInputStream(f1);

          //For Append the file.
          //OutputStream out = new FileOutputStream(f2,true);

          //For Overwrite the file.
          OutputStream out = new FileOutputStream(f2);

          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("File copied.");
        }
        catch(FileNotFoundException ex){
          System.out.println(ex.getMessage() + " in the specified directory.");
          System.exit(0);
        }
        catch(IOException e){
          System.out.println(e.getMessage());      
        }

UPDATE: I checked the folder permissions and they are all open for all users and mine

Apache Commons IO is also another way to go, specifically FileUtils.copyFile(); it handles all the heavy lifting for you.
