Your computer clock maybe wrong......

could be made to sync time though

i started teaching myself java then errr stopped

yep it does

i broke mine, Windows won't ever have the precision of 10 seconds again

Yeah, I suppose it could be modified to sync the time. I've been learning java for about a year and a half now, but they don't teach us much to do with interaction with windows (and I can't be fecked learning )

i wish they taught it in pill form, that would be cool

A FileMoving program I made. It takes about 50-75% of the time windows takes to move the same file (which is quite surprising considering how slow java is in comparison to 'real' languages)

[Tifosi]

import java.io.*;

public class FileMover
{
	public static void main (String[] args) throws IOException
	{
		BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
		// Set up BufferedReader to take user input
		
		System.out.print("Enter the filename you wish to move: ");
		
		String fileToBeMoved = in.readLine();
		// Read in the pathname from a user of the file they wish to move
		
		File file = new File (fileToBeMoved);
		// Create a new file object with the path from above
		
		while(!file.exists()) // While they don't enter a real file
		{
			System.out.println("The file you've entered does not exist.\nPlease try again: ");
			// Tell them they didn't enter a real file
			fileToBeMoved = in.readLine();
			// Read in a new pathname
			
			file = new File (fileToBeMoved);
			// Create new file object...
		}
		
		long fileLength = file.length();
		// Get length of the file to be moved
		
		System.out.print("Enter the destination path: ");
		String destpath = in.readLine();
		// Read in destination path from user
		
		File dir = new File(destpath);
		// Create a new using the destination path from the user
		
		String pathname = file.getAbsolutePath();
		// Get the full path of the file the user inputs (e.g. C:\Windows\System32\winmine.exe)
		
		System.out.println("\nYou are about to move: \n\n"+pathname+"\nto \n"+destpath);
		System.out.print("\nIf you're happy with this, enter 'y' to proceed.\nOtherwise press 'n' to cancel: ");
		
		char userInput = (char) System.in.read();
		// Read in one char from the user
		
		if(userInput == 'y') // If the user enters a 'y' (i.e. they want to move the file)
		{
			double start = System.currentTimeMillis();
			// Get current system time (to be used in calculation later
			
			boolean fine = file.renameTo(new File(dir, file.getName()));
			// Move the file (by renaming the path)
			// Set the boolean value "fine" to true if the transfer goes OK, otherwise set it to false
			
			double end = System.currentTimeMillis();
			// Get current system time (after the move operation)
			
			double timeTaken = (end - start)/1000;
			// Calculate how long it took to move the file (division by 1000 gives result in seconds)
			
			if(fine) // If the file move went OK
			{
				if(timeTaken > 0) // If it took more than "0" time to move (to counter possible division by 0)
				{
					double transferRate = ((fileLength/1024)/timeTaken); 
					// Calculate transfer rate for the file
					
					System.out.println("\nFile "+fileToBeMoved+" is "+fileLength+" bytes and took "+timeTaken+" seconds to move");
					System.out.println("Average transfer rate was "+Math.round(transferRate)+" kB/sec");
				}
				else // If it didn't take more than "0" seconds
					System.out.println("\nFile moved successfully");
			}
			else // If "fine" is false (i.e. if there was a problem with the move
				System.out.println("\nFile not moved");
		}
		else // If the user cancelled the transfer (by entering other than 'y' above)
			System.out.println("\nYou have cancelled the move\n");
	}
}

Commented version of above (if anyone wants to learn anything from it

Sample run (obviously it's simple with no real GUI):

A FileMoving program I made. It takes about 50-75% of the time windows takes to move the same file (which is quite surprising considering how slow java is in comparison to 'real' languages)

The only reason that java is slower than 'real' languages is because it has to be interpreted first. If that is a relatively small part of the procedure compared to the actual work done there is no reason why it shouldn't work almost as fast.

Your claim that it is faster than windows doing the same file move is almost certainly wrong. When windows moves a file, it has actually finished moving it when it says it has finished. In contrast the java program hands that task over to windows. Windows will have cached some of the move and allowed the java program to continue. Windows will still be moving the file while your program is waiting for you to "Press any key to continue...".
