2,083,327 | 2,083,328 | Label production using layout manager or null | <p>I have to create a label to be used for deliveries. At the moment because it is being pushed as needing a quick solution i am creating a JFrame putting all the components on then saving the contents as an image and disposing the frame so it flashes up for an instant and then vanishes, ready to print out. If I know the Label will always be X by Y would it be better to set the layout manager as null and place the components in the positions I need them or would it be better to use a layout manager? </p>
<p>I am currently using a flow layout manager and had to set the preffered size of the sender panel to be a bit larger so that it moved down to the next section (under the barcode). Is there a particular LayoutManager that would be good for this?</p>

613,638 | 613,639 | SoftReference nulls too early | <p>I have a bitmap cache in my Android app where the bitmaps are referenced via SoftReference. However the bitmaps are nulled too early. There can be 20 bitmaps max in the cache, if I load more, GC starts to null the SoftReferences. Without SoftReferences, I can have about 110 bitmaps in cache. Isn't SoftReference supposed to null just before OutOfMemoryError would happen?</p>

<p>Obsolete prevents a property from being serialiazed, why did MS do that? Obsolete doesn't necessarily mean I don't need it anymore. For example, I mark a property as obsolete because I need to tell other programmers to not use it, but still I need it to be serialized.</p>

598,459 | 598,460 | Android layout design for many menu options | <p>What is the best way to go about designing an Android application that features quite a bit of formulas and conversions? I was thinking that multiple Activities with ListViews sort of like a tree with the leaves being the actual calculations. However, after reading Android design principles it's better to avoid a pure navigational structure and try to reduce the deepness of the app.</p>
<p>For example:</p>
<pre><code>Main Menu
Conversions
Weight
Distance
Distance - Speed - Time
Calculate air speed
Calculate distance traveled
Weather
METAR
TAF
</code></pre>
<p>So by the 3rd or 4th screen we've reached the actual individual calculator. Does this make sense? And if it does, is there a better way of designing this (maybe using action bars or tabs)?</p>

[theDateFormatter setLocale:currentLocale]; // I have tried to comment this out... no change

Then i made AlertDialog to run if SQL is empty to inform the user that in needs "instalation" and after confirm i wanted to make loading box while it's running inserting the SQL...</p>

2,350,606 | 2,350,607 | Accessing a class with the exact same name | <p>I have a tricky question and I'm not sure if it is even possible in Java. I'm in the following
situation:</p>
<p>I got a class A that uses another class, let's call it B. Now, I'm trying to write a third class (and I don't call it C), I call it B again (to be sure which class 'B' I mean, I will call it B1 and B2 in the rest of this post, ok?). All three classes resides in three different JAR-files. So far, so good. </p>
<p>Normaly, class A finds class B(1) on the classpath and will use it. But now I'm putting the JAR-file that contains B(2) at the very beginning of the classpath, so class A will find this class instead of the old one. So my class B(2) can act like the old class B(1) (which is a library in reality, that I can't customize in any other way. that's why I am doing that...).</p>
<p><strong>And here comes my problem:</strong> In my class B(2) I want to load the real class B(1) and use it. I can do this so far by using reflection. I can even invoke methods via reflection, but I can't cast an instance of the loaded class to B reference. Here is the exception:</p>
<pre><code>java.lang.ClassCastException: my.a.ClassB incompatible with my.a.ClassB
</code></pre>
<p>Has anybody an idea how I can use class B(1) in class B(2)? I am happy with any workarround...</p>

5,710,106 | 5,710,107 | Is there any method to pause a function in the middle waiting for input in javascript? | <p>I need to pause a JavaScript function execution in the middle and then resume it after a table cell is clicked. For example : I have to put 'A' into a one of the table cells. So, I have to click add() (add() is a function) and then wait for the user to click on the table cell to pass the cell id to function. I have thought of bind a click event to each cell to trigger the add() function. But then I have to do a delete function too. It is the same that I click on the delete button and then wait for the user to click on the table cell to pass the cell id to the function. </p>
<p>So how can I pause the function to wait for the input just like C++ : cin>>x which the program waits until user inputs the value of x.</p>
<p>Edited:
Finally I work it out. Every time when I click on the add button, I bind a addtd function to every td. And after I click on the cell, I unbind the addtd function. So that next time I click on the delete button, I can bind a deltd function on each cell.</p>

<p>I then wait for fresh data and when i get it I insert it AGAIN into data1 and add it to ftsedata. Although ftsedata seems to be increasing in size correctly it seems that elements of ftsedata are just pointers to data1 and hence all elements of ftsedata seems to have values equal to the last data1 values.</p>
<p>I am using arraylist because I do not know how many datapoint will come in during the day so i need something that expands.</p>
<p>Could someone please tell me if I should be using arraylist or something else and if arraylist what is my problem.</p>
<p>many thanks for your time.</p>
<hr>
<p>Many Thanks everyone,</p>
<p>I actually have four different functions that each fill one part of data1. Taking your views on board, i left data1 alone as a variable that can be seen in all functions. In the particular function that adds data1 to the arraylist i created a dataLocal variable of type Data and copied everything into it like
dataLocal.price= data1.price;
etc etc
I then added dataLocal to the arraylist. This seems to work.
I am assuming that each time this function is called a new local variable with the name dataLocal is created. Thanks you all for your help and please let me know if there is somethimng in this way of doing things that can get me in trouble later,eg, some other part of program would write over one instance of dataLocal because as far as the program is concerned the need for the variable is over.</p>

5,236,892 | 5,236,893 | Modifying item after addition to List does not update list | <p>I have a member variable which is a list of reference types. In a method I create and item, add it to the list.

<pre><code>Item localItem = new Item(arg1, arg2);
this.itemList.Add(localItem);
// Do some testing and assertions
localItem = new Item(arg3, arg4); // This does not update the instance of

Recently, a client asked me to develop an Android app for him, wich, will most likely run on a Samsung Galaxy S or Galaxy S II, with Android 2.3, that basicaly consists in connecting a standard smartcard reader on the USB port of the device and using it to access the smartcard.
I have programmed smartcards before, but I have no experience with android. So my questions are:</p>

<p>Will I have to write my own driver to interface with the USB?</p>

4,386,740 | 4,386,741 | can you have multiple hashcode and equals | <p>Alright, I need to be pointed in the right direction. I already have a hash code and an equals method with over ride. </p>

return false;

return mdc.type.equals(type) && mdc.type2.equals(type2) && mdc.type3.equals(type3);
}
</code></pre>
<p>now what if i want to only compare the first and second type and not the third? Can I have two hash and equal methods for later use?</p>
<p>What I want to do is, if type 1 and type2 matches, delete them from the current arraylist and add them to a new list, showing which ones were the same type. This is different from the hash code shown above. </p>
<p>Is there another way within an array, I can see which combination of type1 and type2 appears multiple times? </p>
<p>Ex:</p>
<ul>
<li>Shooting Halo</li>
<li>Shooting CallofDuty</li>
<li>Racing Forza</li>
<li>............</li>
<li>.........</li>
<li>..........</li>
<li>Shooting Halo</li>
</ul>
<p>Shooting Halo appears twice, they need to be removed and added to another list, but problem is that I already have a hashcode for previous use.</p>
<p>Edit: I want to thank everyone for their ideas. I have solved this problem by creating another object class with similar getters and setters but with a newer hash code and it worked. Next time I will use a better logic method. My main goal on this post was to know if there was any way to have multiple hashcode and method in one class which apparently isn't possible. :)</p>
