java - Sort 4 numbers without array -


I have a practice where I will put 4 numbers in ascending order and then without using the array must descend>. I can only use the loop and if the statement I have done it with 3 numbers, but now with 4 numbers I am unable to think about logic. 

  Float is great = 1, great 2 = 0, great 3 = 0, great 4 = 0; Int a = 7, b = 5, c = 6, d = 0; // descending (a & gt; b & amp; amp; amp; nbsp; c) {great1 = a; Great 2 = b; Great 3 = C; } And if (a & gt; b & amp; b> c) {great1 = a; Great 2 = c; Great 3 = B; } And if (B & G; A and A and A> C) {great 1 = B; Great 2 = A; Great 3 = C; } And if (B & G; A & A & A & l; c) {great 1 = B; Great 2 = c; Great 3 = A; } And if (C and G; A and A & gt; B) {great 1 = C; Great 2 = A; Great 3 = B; } And {great 1 = C; Great 2 = b; Great 3 = A; }

One Usage: 

  int tmp ; If (a & gt; b) {tmp = a; A = B; B = TMP; } If (C & gt; d) {tmp = c; C = D; D = TMP; } If (A> C) {tmp = a; A = C; C = TMP; } If (b> d) {tmp = b; B = D; D = TMP; } If (b> c) {tmp = b; B = C; C = TMP; }

You can use to create the optimal sorting network for a low number of input.

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.

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

The code works in my place, although the new HTML / CSS does not render after every iteration of the loop and when all this is done, then display only the text of 100 px size.
