I need help updating the position of my moving circle in my Java Applet. Whenever I try to make it move faster it doesn't work. I need to be able to adjust the speed of the moving circle. What is wrong with my code?

import java.awt.*;

import java.applet.Applet;

public class phys extends Applet{

public static int height = 500;

public static int width = 500;

public static int radius = 126;

public static int y = 0;

public static int x = 0;

public static int xVel = 15;

public static int yVel = 15;

public void paint(Graphics g){

setBackground(Color.white);

setForeground(Color.black);

g.drawOval((width / 2 - radius), (height / 2 - radius), 2 * radius, 2 * radius);

g.drawOval(x, y, 5, 5);

if(x == 500 && y == 500){x = 0; y = 0;}

try{

Thread.currentThread().sleep(1000 / 60);

repaint();

}catch(Exception e){}

}

}

I want to use <nul set /p= combination of commands to print spaces and tabs. How do I do this? I don't want to use echo as it results in a new line.

On the Windows DVD there are a bunch of files. Among them is a file called "bootmgr". The problem I'm having is figuring out the extension of this file. I went and changed some properties so that Windows displays all file extensions but it's still not showing one for this file. I understand it's a boot manager of some sort but it just doesn't make sense, not to have a file extension if it is a file. Under that file is another boot manager but it has a file extension, it's called "bootmgr.efi", and I know what it does and why it's there. It's the other, unknown boot manager, that's bothering me as I don't know what it does and what kind of file it is? Does anyone know the answer to that?

I have a Java program where I append text to a JTextArea. I have several lines of appending text and I wish to put a pause in between each one. The problem is when I use the conventional Thread.sleep() method, all the pauses happen at once and then the text gets appended. Why is this and how can I get around it?

I have a JTextField and I wish to make the mouse invisible whenever the user hovers the mouse over it. Basically, make the mouse gone when it is positioned over the JTextField. Is there a way to do this?

If I install e.g. Battlefield 3, how does Windows recognize it as one of the installed programs on my computer? Does is have to do with registries? If so, where could I see the list (other than Control Panel - Installed Programs)?

I downloaded Origin onto my desktop to be able to play on it as well as my laptop.The problem is when I transfer the corresponding files into the corresponding folders, from my laptop to my desktop, Origin still says: "Not able to run the game. It is not installed on your system.". There must be another folder with all the information somewhere. Where is this folder? I wish to copy it from my laptop to my desktop.

My friend and I are connected to a WIFI home network with our two laptops. I wish to send him a message using Batch. Is this possible? I've read a lot on using Batch and the 'net send' command to communicate but this doesn't see to work if you are not in a school-like computer network. Is there a way to achieve this?

Does Java have a way of finding out the speed of the processor or must I improvise with huge numbers and them trying to measure the time it took to perform a calculation with them? If there is a way how could I do it? Code description would be appreciated!
