java - how do u read all doubles from txt file? -


It's easy when there is a file of all doubles, but when a non-double is somewhere in the middle, then I It does not enable it to catch all of them.

For example: 

  604.2 609.2 6042 604.4 4234.324 312 gfsdgfreg 6043 604.3

Output: 

  604.2 609.2 6042.0 604.4 4234.324 312.0

Obviously, two pairs are missing, is there any way to catch them all , Which use the Hydicted Double ()? If thx in advance u do not receive a reply. I have seen somewhere that I can parse each of them for doubling the exception and catching, but I'm not really advanced

What's here with me: 

  import java util *. Import java.io * *; Public Class Lab11 {Public static zero main (string [] args) FileNotFoundException throws {file nums = new file ("file.txt"); Int size = arrSize (nums); Double [] phonenum = copy (nums, size); (Int i = 0; I & lt; Phone no. Lamp; I ++) system. Out.printLN (phoneme [ii]); } Public static arrSize (file f) throws FileNotFoundException {int arrSize = 0; Scanner = new scanner (f); While (in.hasNextDouble ()) {arrSize ++; Next (); } In.close (); Return arrSize; } Public Static Double [] Copy (File F, Integer Size) FileNotFoundException throws {new scanners (F) in scanner; Double [] list = new double [size]; Int i = 0; While (in.hasNextDouble ()) {list [i ++] = in.nextDouble (); } In.close (); Return list; }}

I will give you two of the following structures: 

  while (in.hasNext ()) {if (in.hasNextDouble ()) {// loop code in your internal time} else {in.next (); }}

Otherwise, you will remember everything after the first example of non-double.

sqlite3 - UPDATE a table from the SELECT of another one -

I have the first table article where some data is missing. In the table, articles_tmp I have a part of the missing data. So I want to update the articles. Where the path path is data in articles_tmp.path where the path is not zero . With SQLite , it does not work: update article SET path = (SELECT at.path FROM Articles_tmp as AS, WHERE at.article_id = a.id and a.asp, the text is in the form and not on. It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help?

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
