Measure Current Download Speed Of File?
Jan 5, 2014
Is there a way to measure current download speed of a file being downloaded? I've searched all over google and the only thing i get is average download speed. This is basically how it is being done, the result is average download speed.
Java Code:
OutputStream out = null;
URLConnection conn;
InputStream in = null;
long startup = System.currentTimeMillis();
try {
URL url = new URL(adress);
out = new BufferedOutputStream(

I have a FileChooser:
JFrame parentFrame = new JFrame();
JFileChooser fileChooser = new JFileChooser();
fileChooser.setDialogTitle(txtPushCode.getText());
int userSelection = fileChooser.showSaveDialog(parentFrame);
if (userSelection == JFileChooser.APPROVE_OPTION) {
[Code] ....
But as you can see, it downloads only to "C:android empcoloricon.png". I want to download it to path where I chose in FileChooser with the name and extension I choose. In short, how can I use dynamic file path names in where ever I want in my applications?

First of all, i am using ubuntu and jdk8. My problem: displaying the current path of a file in my system Approach: I have a file called dummy.txt in a given directory which have enough permissions and i did the following:
File file=new File("dummy.txt");
System.out.println(file.getAbsolutePath().substring(0,file.getAbsolutePath().lastIndexOf("/")));
I expected to see displayed the current path of the file without the name of the file but it is showing a different path. I just want to display the current path of the file without the name.

When creating VRML, there is a convention that one unit corresponds to 1 metre in the real world. This makes sharing models easier. Is there any similar convention for JavaFX 3D?

I'm working on a project for class that asks me to record punch-in and punch-out times for employees. However, I am having difficulty figuring out where I am going wrong as none of the information will write to the text file in the ArrayList that I have created. The code is as follows:
import java.text.*;
import java.util.*;
import java.io.*;
import java.nio.file.*;
public class TimeClockApp {
// declare class variables
private static EmployeeDAO employeeDAO = null;
[Code] .....
I want to keep the coding as simple as possible as I am new to Java, and have spent hours upon hours trying to figure this all out. The console output looks like this:
Welcome to the Punch-In/Punch-Out Screen
Please choose an option below:
I. Punch In
O. Punch Out
Choice: i
PUNCH IN
--------
Enter Employee ID:
8
8Punch-In Date & Time: 2014/05/28 22:44:26
[]
Press enter to return to the main screen:

I currently have the following code that I use to download a file from a website:
URL website = new URL(imgurl);
ReadableByteChannel rbc = Channels.newChannel(website.openStream());
FileOutputStream fos = new FileOutputStream(dir+""+imageNumber + "." + extension);
fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);
fos.close();
Usually, the code works very well. But sometimes, the download gets stalled indefinitely. Is there a way to set a time out period for the downloading of this file?

I want to be able to use the current date to solve a math problem, specifically as follows:If today is March 17, the math problem of the day should be:
(Month times Day of Month) + 99 = Answer of the Day
(3 x 17) + 99 = 150
How can I create a java script to find the current month and the current day of month, multiple those two together, then add 99 and display the answer as a result.

Recently we got an issue about file download. We are using below code to fetch the data from backend(DB2) and export to excel.
Before Jan 15 it use to take 2 minutes to download the file (2 MB size). But now its taking half an hour to download.
response.setContentType("application/vnd.ms-excel");
response.setHeader("content-disposition","attachment; filename=Attendance_Report.xls");
We have restarted server, system but still problem exists. We found that there is no code level or data base level or network level issues.
Now we have to see server level issue. What are the factors which effects the file downloading at server level.
We are using websphere 6.1 ,java1.4

I have to write a program that asks the user to enter "air", "water", or "steel", and the distance that a sound wave will travel in the medium. The program should then display the amount of time it will take. The amount of time it takes sound to travel in air can be calculated as follows;
Time = Distance/1,100
The amount of time it takes sound to travel in water can be calculated with the following formula:
Time=Distance/4,900
The amount of time it takes sound to travel in steel can be calculated with the following formula:
Time=Distance/16400
Here is my code:
import java.lang.String;
/**
This program displays numbers padded with leading zeros.
*/
public class SpeedofSound {
public static void main(String[] args) {
double D; // declares this as double
D = keyboard.nextDouble();
const double A = 1100; // declares this as a constant
[Code] .....
The following is the error I'm getting:
----jGRASP exec: javac SpeedofSound.Java
error: Class names, 'SpeedofSound.Java', are only accepted if annotation processing is explicitly requested
1 error
----jGRASP wedge2: exit code for process is 1.
----jGRASP: operation complete.

So i'm using Netbeans and have created this template for the program i want to create. Basically what I want to do is enter a time and date in 24hr format including seconds and the date of start and end time and have the program calculate the time difference between Tool launch and tool Receive that takes into factor the Launch and Receive Dates for a total of hh:mm:ss duration. I don't know how to combine both those factors output one number in a total number of hours Duration. I'm also having problems linking the ODO (odometer) which the formula would basically be time/ODO (or distance in feet) = x.x ft/sec format.

I was making a pong game, part copied code off the internet, part my own code, part my friends code. It works well enough, but the ball starts at one speed, and stays the same. I would like to know how to make the ball slowly increase.
It is a java applet, which shouldn't casue any harm right?
My code:
Pong Applet
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Pong extends Applet implements MouseMotionListener, KeyListener {

if I move object A to one area of the screen I want object B to to move to object A's location but I also want object B to move at a fixed speed (movement variable). How do I go about doing this? Both the x and y coordinates of object B would need to know the coordinates of object A to calculate the distance between the two and to determine how much of which axis to increment/decrement (if that makes sense?) with the inclusion of the speed variable.In other words I'm just trying to create a homing object.

I wrote a code from our text book for Pong. Im trying to figure out how to fill the ball with color. Im also wondering how to speed the ball up once there is contact with the paddle. The initial speed is ok but once contact is made with the paddle, it slows down. Makes it too easy to play. Here is my code so far. As far as the game goes, it works and is good. Just wanted to add a couple customizations.
Java Code:
package pong;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Font;
import java.awt.FontMetrics;
import java.awt.Graphics;
import java.awt.event.ActionEvent;
