Java :: Best Standard Style For ToString Implementation?

Oct 15, 2010

We have a lot of objects for which we like to implement a simple toString to output attributes of the object. Some of these attributes may be complex objects themselves. Is there any standard, or simply just a best practice for a style? I'm thinking something like:
[SimpleClassName] { prop1:value, prop2:value }

In which case a nested value would look like:
[SimpleClassName] { prop1:value, prop2:[NestedObject] { prop3:value}}
We are using Java but I find myself asking the same question in most languages!

Use .toString() - Comparing Array's?

Jun 30, 2009

I have an array which has strings for the key instead of numbers. when i use .toString() on this array, it does not output a string, leading me to believe that .toString only works when you have numerical keys. Is there an easy way I could compare two of the above arrays?

ActionScript 3.0 :: Add Leading Zero Using The ToString() Function?

Mar 15, 2010

I've looked in the user manual and I can't find any reference to toString() for syntax information. Isn't there a parameter for me to use to specify the string lenght? And whether to add leading zeros or not?Here's the code I need to add leading zeros:

function playSound(e:Event){ SoundMixer.stopAll(); var num:Number = Math.ceil(Math.random()*43); bigNum.text = num.toString(); var path:String = "Track No" +

Asp.net :: Remove Special Characters When Doing A DateTime.Now.ToString()

Sep 17, 2009

So I have a flashobject which I need to pass a formatted DateTime string to.

My code:

string date = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");

which outputs as: 2009-09-16 22:26:45

However when it is actually output to HTML and swfobject it renders it as:

so.addVariable("inNowDate","2009-09-16+22%3a25%3a13");

I think this is messing up a calculation that the flash object does based off the current time. Do I need to encode or decode this?

Actionscript 3 :: Bubble Pop Game / Defining ToString Method Through Reference With A Static Type Class

Apr 3, 2012

I have the actionscript code here for a bubble popping game. When the game starts, bubbles fall down from the top of the game to the bottom and score is kept for the most bubbles clicked or popped in 30 seconds.The size of the bubble is defined by the initialize method in the code, and uses ToString() to calculate the score. ToString gives me a 1061: Call to a possibly undefined method Random through a reference with static type uint. This error which I cannot figure out where it comes from.[code]

Java :: Migrating Existing Java And Flash Applications To Android (Google TV)?

Aug 9, 2011

I have a client-server multigame suite for PC ("kind of" cross-platform using cygwin), which is developed in Java(game menus and database management), C++ (server side), and adobe Flash (game graphics & interaction).

I have never tried to develop for android, so i have no experience.I am thinking of migrating this suite to google TV. So i would like someone with android experience to give a clue on the following :

1) Is it going to be easy to migrate the Java application to an Android application?

2) What kind of Flash support does Android have? Can it load directly swf applications? Does it have to load swf's through browser?

3) Can i find any kind of performance indexes for google TV hardware?

Java :: Load External Page HTML Via Javascript Or Flash Or Java?

Nov 13, 2011

I need to load somehow the html code of a webpage A into a javascript string of another webpage B, on a different host. I know this is impossible to do with javascript alone because of the same origin policy, and I know I could do it loading the page via php on my server and then send results back to the user's client but I wouldn't be able to handle so many requests, so I need it to be done directly by the user's browser. I can use nearly whatever browser scripting language/applet framework common enough to be installed on the majority of my users' computers, like flash and java.On example, what if I use flash or java to load the external html code and then call a javascript callback function providing the source? Could this work?

Java :: Any Opensource Alternative To Squish To Test Flash / Silverlight / Java Applet Gui Objects?

Jun 3, 2011

If one doesn't have the source code, the only to test is to send keystroke and mouse move so I found this product but it's not free and opensource price is not even known :([URL] Squish supports automating interactions and testing non-HTML/DOM elements, that is, native objects, which are embedded in a web page. This is done at a fairly abstract level, which means that mouse and text input can be recorded and replayed.

In addition it is possible to inspect embedded native objects with the Spy tool and to insert verifications for these native objects. All of a native object's public properties can be accessed in test scripts.

AS3.0 :: Java - Flex - ArrayList Of Custom Java Objects Over BlazeDS

Dec 7, 2010

Right away i just try to explain my problem: Using BlazeDS i got the following Javaclasses:

[Code]...

Then i got a Flex service class calling BlazeDS and executing the getCategories java method. Since Flash dosn't seem to understand typed arrays, the result from that method which i get back in flex is a simple array of untyped objects (the mapping dosn't seem to work here, even tought the class category exists in flex and has the same properties).
thats the first thing. but however, i'm converting the untyped objects manually into objects of the category.as class. the second thing is that categories have child-categories within the java object, which are also ArrayLists of the type category.java. the problem about that: my result event object only contains the first level of categories, looking into them the children are allways null. i dunno why they are empty, since they ARE part of the java object category.

and the third thing (the strangest by fast), you maybe noticed i named the properties of the category.java class strange, like idCat and nameTest instead of simply id and name. why that? because the property names of my flex result objects dont seem to change when i change the java objects properties names (result object properties are named "id" and "name" but the java class object properties are named "idCAT" and "nameTEST"). that it REALLY strange, since if i set the properties, like you see at nameTEST = "TESTNAME" it IS recogniced by flex, only the proertyNAMES dont seem to be recognized at all.

My question is this. where someone would want to turn a number into a string or a string into a number? and how would someone even turn a string into a number? i dont understand how that works.
