I ma trying to implement Java "watchService". I am unable to register network mounted drive path. Is there any solution for this.
Path ftpFolder = Paths.get("H:/Ftp/Incoming/");
where H is mounted Drive.
I am trying to connect a remote machine but I can't. There is a shared folder in the remote machine, when I write the path to file browser in local machine, it does not find the path specified. Both machines have successful network condition and ping each other. Also, the shared folder is opened to everyone, there should not be a permission problem, right?

I am trying my hand on JNS as i need to deveop a key-distribution scheme (random Key-Distribution scheme) using a simulator. As i have experience in java, i thought to use JNS instead of NS2/NS3 which seems very complex to me.

if (!item.isFormField())
{ fileName = item.getName();

I am creating a web application that runs on server X(unix) and it has another unix system mounted on it. I want to generate the file tree structure of this mounted unix file system and show it on to a web application so that users can select a file and move it onto this current unix machine.
I know this sounds stupid and you may want to say why cant we directly copy the file, I am doing a proof of concept and using this as a basis.
I am copying the xml files from one folder to other folder, in the source folder, i have some files which have some content like "backing File="$IDP_ ROOT/metadata/iPAU-SP-metadata.xml" but while writing to the destination folder.i am replacing the "$IDP_ROOT" with my current working directory. The entire copying of files is for deploying into tomcat server. The copying is done only when server starts for the first time.Problem: If i change the folder name from my root path in my machine after i run the server,the entire process will be stopped because the destination folder files already contains the content which is with existed files names or folder names.
So i want to change it to relative path instead absolute path. What is the best way to do it? Please look at code below:
[ // Getting the current working directory
String currentdir = new File(".").getAbsoluteFile().getParent() + File.separator;
if(currentdir.indexOf("ControlPanel")!=-1){
rootPath=currentdir.substring(0, currentdir.indexOf("ControlPanel"));
}else{
rootPath=currentdir;

I have been playing around with a snippet I wrote to get the Label on a drive (below). It works fine for me (though I will take any constructive criticism). My question is whether the is a way to set the drive label, purely with Java. I know I could call command line, or even resort to using the Windows API

The customer will give the money and the total will show the customer money and the balance will come out after the total is deduct with the price.
I want to know which Java class and method that can be called in order to copy the content of a flash drive(usb) without opening the flash drive. If possible also to know the prodecure on how to do it. I've tried some overloaded methods of copy() from the java.nio package.

We're told to make a cash register program for 5 products using Java. It loops until "-1" is entered on the "Continue?" input dialog box.There should be a:
1. Main Menu - where the user will pick what to buy (one product at a time) like the sample code below and prompt the user if he will buy another product or not. If yes, the program will go back to the main menu to buy another product and if not, continue to the program. And it looks something like this: LEvFOwQ.png
2. Receipt - at the end of every transaction.
3. Daily Sales Report where it shows all receipts then grand total like:
Transaction 1
-subtotal
Transaction 2
-subtotal
and so on then,
GRAND TOTAL
4. Inventory Report where it shows the Items Available before the Selling, Items Sold, and Items Available after Selling in table format.
Below is the code for a simple cash register for only one product that I made but I need to upgrade it for it to work for 5 products. That code will serve as the basis for this program.make the switch or if-else statement for the main menu first and if I got it right I try doing the rest.
int userQty1 = Integer.parseInt(JOptionPane.showInputDialog(
"Product ID Product Name Product Quantity Product Price"
+prodID1 + " " +prodName1 + " " + prodQty1 + " " +prodPrice1 "
"
+ and so on until prod5));

How to upload file to google drive using java. my java code is.
HttpTransport httpTransport = new NetHttpTransport();
JsonFactory jsonFactory = new JacksonFactory();
GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
httpTransport, jsonFactory, CLIENT_ID, CLIENT_SECRET, Arrays.asList(DriveScopes.DRIVE))
.setAccessType("online")
.setApprovalPrompt("auto").build();

So in that file object(java.io.File fileContent = new java.io.File("document.txt");) asking complete file path. But in file upload we can get only file name not path.
I am trying to create a slightly modified cash register. The user will enter the amount of the item, the payment received, calculate the change/refund, and then allow the user to choose the preferred bills.
import java.util.Scanner;
public class Register {
private static Scanner input;
public static void main(String[] args) {
input = new Scanner(System.in);
System.out.println("*****CASH REGISTER*****" );
System.out.print("Item Amount: " );
int amount = input.nextInt();
[Code] ....
I will try to clarify the code, to make things a little easier to interpret. in the refund method, I have set up a 2-d array to exist and function as an excel sheet. The refund amount is passed to the method and compared to each bill of the array. Once the refund is determined to be greater than a bill, the user is prompted to enter the preferred bill type. This is where my problem is...I would like the program to then calculate the number of bills and keep a tally of those bills in the 2nd column and then determine the new refund amount at which point the user will be prompted again to determine the desired bill.
Then print out the array of bills that are not equal to 0.

This question has confused me because "Errors" are capitalized and I'm not sure what they mean.
To me this question is false. Sockets can be used to transfers file over a network.
I can't see why this wouldn't work. The code looks fine to me.
I don't think this is true unless you're using the mouseEntered() or mouseExited() method. But again, I'm not sure.
I think this is true, I don't know what else could have listeners.
They're only worth a few marks each so the answer is only suppose to be a line or two. They are all true or false questions that require an explanation.
I am trying to develop an application which will be showing a TimeSeries graph(related library JFreeChart) displaying network activity related to a particular network interface embedded in a JFrame.I have created a JPopUpMenu which is having containing a list of JMenuItems showing network interfaces as their String values.Menu is popping up correctly
Further I am selecting a JMenuItem related to a particular network interface to show network activity in TimeSeries graph.On selecting a JMenuItem I can see that graph is moving on constantly but not able to see any network activity.
Pasted the code below :
