3,603,261 | 3,603,262 | Memory allocation/reference comparison for ints and Integers | <p>With the following:</p>
<pre><code>String a = new String("test");
String b = "test";
System.out.println(a == b); //false
</code></pre>
<p>We get false, since <code>String a</code> is an object, so <code>a</code> points to a different location in memory than the string literal, <code>b</code>. I wanted to see how this worked for <code>int</code> and <code>Integer</code>:</p>
<pre><code>Integer x = new Integer(5);
int y =5;
System.out.println(x == y); //true
</code></pre>
<p>I though that <code>x.equals(y)</code> would be true, but <code>x == y</code> would be false as it is in the case with <code>Strings</code>. I understand that we compare <code>ints</code> with <code>==</code>, but I figured that comparing an <code>int</code> to an <code>Integer</code> would be different. Why is this not the case?</p>
<p>I assume that in this case using <code>==</code> won't work for comparing references, so how would we do it (not sure if this is practical, but I'd like to know)?</p>

5,951,469 | 5,951,470 | Enum internationalization exception | <p>I have an enum and I tried to internationalize it like:</p>

return Messages.get("activity.project.created");

<p>Now, please note that the keys defined in my messages.properties contains string formatters like:</p>
<pre><code>activity.project.created = User <%s> created project <%s>
</code></pre>
<p>Well, the issue is that when I do something with this enum in other places in the code, it throws an exception like:</p>
<pre><code>MissingFormatArgumentException occured : Format specifier 's'

<p>so basically it wants that when I get the key in <code>toString</code> enum class, to apply also the args for formatting but this I only do later where I use that enum...</p>
<pre><code>activity.summary = String.format(activityEnum.toString(), args);
</code></pre>
<p>Can you please give me a suggestion of how to handle this?</p>
<p><strong>UPDATE</strong>:</p>
<p>If I use the classic way, all works nice:</p>
<pre><code>PROJECT_CREATED("User <%s> created project <%s>"), PROJECT_EDITED(
"User <%s> edited project <%s>"), PROJECT_DONATION(
"User <%s> made a donation of <%d> to project <%s>");

<p>That would return anyone with "john" in their names, including John, Johnathon, Johnson, etc.</p>

<p>The second if statemenet I want it to return all those items with "DPFle-" in front of all the names, and simialr for the third.</p>
<p>At the end of all the if statements (this is in a for each) I want it to read the entire list.</p>
<p>how owuld I do this?</p>

The tool will be used for a joinery website. What I am wanting the form to do is add values from different drop down lists and produce a quote price.</p>
<p>The form would have several drop down lists for example: item, size, finish, wood type etc. Obviously each item would have different sizes, finishes etc so these would need to be dependant on what item the user selected. The user would be able to select different values for each drop down box and then they would hit a calculate button. this would then produce a quote for the dimensions etc that they have selected.</p>

<p>So my question is what is the easiest way to run these operation (that access the database) async??</p>
<p>I forgot one important feature that the application requires, the user will have the option to cancel any operation at any time.

3,235,350 | 3,235,351 | Multiple 'endings' to a function - return an object, return a string, raise an exception? | <p>This one's a structure design problem, I guess. Back for some advice.</p>
<p>To start: I'm writing a module. Hence the effort of making it as usable to potential developers as possible.</p>
<p>Inside an object (let's call it <code>Swoosh</code>) I have a method which, when called, may result in either success (a new object is returned -- for insight: it's an <code>httplib.HTTPResponse</code>) or failure (surprising, isn't it?).</p>
<p>I'm having trouble deciding how to handle failures. There are two main cases here:</p>
<ol>
<li>user supplied data that was incorrect</li>
<li>data was okay, but user interaction will be needed () - I need to pass back to the user a string that he or she will need to use in some way.</li>
</ol>
<p>In (1) I decided to <code>raise ValueError()</code> with an appropriate description.
In (2), as I need to actually pass a <code>str</code> back to the user.. I'm not sure about whether it would be best to just <code>return</code> a string and leave it to the user to check what the function returned (<code>httplib.HTTPResponse</code> or <code>str</code>) or <code>raise</code> a custom exception? Is passing data through raising exceptions a good idea? I don't think I've seen this done anywhere, but on the other hand - I haven't seen much.</p>
<p>What would you, as a developer, expect from an object/function like this?</p>
<p>Or perhaps you find the whole design ridiculous - let me know, I'll happily learn.</p>

3,648,937 | 3,648,938 | Concurrency Problem in Java | <p>I am designing a client-server chat application in Java. This is a secure application where the messages are exchanged using cryptographic algorithms. I have one server and it can support many clients. My problem is that when one client logs on the server it works fine, but when another user logs into the system, the server starts giving me bad padding exceptions for the encrypted text. </p>
<p>I am not able to figure out the problem, according to my logic, when new connection request to server is made, the server creates a thread for listening to the client. Is it possible that once the instance of thread class is created, it does all the processing correctly for the first client, but not for the second client because the variables in server listener thread class already have some previous value, and thus the encrypted text is not decrypted properly?</p>
<p>Please advise how I can make this process more robust so that the number of clients does not affect how well the server functions.</p>
<p>Hi, The code is like this :</p>
<p>When Server Starts:</p>
<pre><code>Socket in= serverSocket.accept();
Receive rlt = new Receive(in);
Thread receiveReq = new Thread(rlt);
receiveLoginReq.start();
</code></pre>
<p>now the Receive Thread waits for the incoming message and do the process according to message type. When more than one client is invoked, Server works fine, problem starts when one client terminates and then again tries to reconnect. Server always gives the Error in following pattern:</p>
<ol>
<li>First time the HAsh not matched error for second client</li>
<li>Second time javax.crypto.BadPaddingException: Given final block not properly padded error</li>
</ol>
<p>When this happens, I need to restart server and restart both clients, only then both clients works. but again if one client terminates connection and again tries to reconnects, the same 2 errors occurs in the same manner. and then again restart Server. </p>
<p>Any Advise will be highly appreciated.
Thanks</p>
