Ternary operator to return value- Java/Android -


बस php से जावा में स्विच

मुझे निम्न समस्या का सामना करना पड़ा

मैं चाहता हूं फिर से लिखना 

  यदि (usrname.equals (उपयोगकर्ता नाम) & amp; (passwd.equals (पासवर्ड))) {वापस सत्य; } अन्य {वापसी झूठी; }

के रूप में 

  (usrname.equals (उपयोगकर्ता नाम) & amp; passwd.equals (पासवर्ड))? सच वापस लौटिए: वापसी झूठी;

यह काम नहीं कर रहा है (वाक्यविन्यास त्रुटि) हालांकि, 

  int a = 1; Int b = 2; Int minVal = a & lt; बी? ए: बी;

काम कर रहा है

कुछ स्थिति के आधार पर मूल्य लौटने पर टर्नरी ऑपरेटर सही ढंग से व्यवहार क्यों नहीं कर रहा है

संपादित करें < / P> <पूर्व> वापसी (usrname.equals (उपयोगकर्ता नाम) & amp; passwd.equals (पासवर्ड));

समाधान हो सकता है अगर वह बूलियन वापस आती है।

मुझे कहने की ज़रूरत है 

  (usrname.equals (username) & amp; amp; ; Passwd.equals (पासवर्ड))? वापसी "सदस्य": वापसी "अतिथि";

आप कर सकते हैं 

  return (usrname) बराबर (उपयोगकर्ता नाम) & amp; passwd.equals (पासवर्ड))? सही गलत;

true और झूठे को आप जिस रिटर्न वैल्यू में बदलना चाहते हैं उसके द्वारा प्रतिस्थापित किया जा सकता है। अगर यह सिर्फ बूलियन है तो आप टर्नरी ऑपरेटर को पूरी तरह से बचा सकते हैं। बस करो

<पूर्व> वापसी (usrname.equals (उपयोगकर्ता नाम) & amp; passwd.equals (पासवर्ड));

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

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. To see the text as if it is slowly zooming, I need to do this JavaScript is down because it is being used from a different file here is what I have ... < Pre> & lt; P class = "game-title" style = "font-size: 50px" & gt; Test & lt; / P & gt; Function sleep (milliseconds) {var start = new date ().
