Is there assert facilities in JAVA?

I know there are assert facilities in c++ which are very useful for testing and debuging programms. Does Java has the similar things? If not, anyone has developed something like this?
Thank you
Shaomin

Yes and no....
There is a language built-in assert facility in JDK 1.4, but it's still in beta.
If you need pre-1.4 java, you may use 3rd party classes, as pointed by mriffe.

"ASSERT FAILED" when java.exe ends

What kind of error message is this:
ASSERT FAILED:
Executable: java.exe PID 218 Tid b04 Module kswdmcap.ax, 4 objects left active at line blablablablabla
This happens when my java class ends from where I called a c++ method (that controls the windows media encoder sdk). It return without an error message from the c++ part, but when java.exe tries to end the class does this error message appear on the screen (Windows XP). Does anybody have a clue what that might be?

I wouldn't say problem.
Presumably the library you call does something. While doing that it creates "resources" of some sort. It could be a socket. Or a memory allocation. Or something else.
But it expects you to tell it when you are done. Either with the library or with some specific aspect of the library. And you are not doing that before you exit.
Keep in mind that I am only guessing. There could certainly be other explainations - like a bug in the library.

Is there a way for java plug-in to get the browser login authentication

I have an applet that is loaded from a password protected html page. I use java plug-in with the applet.
When I try to read this page I get the browser window asking for password and username. So far so good.
Then I log in successfully and starts using the applet.
If the applet wants to access pages on the same PW protected area, I have to give the plug-in PW and UN.
My question is then:
Is there a way that java plug-in can get hold of the login information that the browser has obtained? (So that I wont have to give the same information twice)
I thought the answer would be no, but then I started experimenting with https and found out that if I use the same scenario as above, except from that I give a certificate to the browser before the first login, then the plug-in will get certificate info from the browser, and it wont promt me for UN and PW either!
When it is possible for the plug-in to obtain certificate info and login info from the browser then it should be possible just to get the login info with ordinarily http?

How to parse a string in CVP 7.0(1). Is there a built-in java class, other?

Hi,
I need to parse,in CVP 7.0(1), the BAAccountNumber variable passed by the ICM dialer. Is there a built-in java class or other function that would help me do this?
Our BAAccountNumber variable looks something like this: 321|XXX12345678|1901|M. In IP IVR I use the "Get ICM Data" object to read the BAAccountNumber variable from ICM and then I use the "token index" feature to parse the variable (picture below).
Alternately, IP IVR also has a Java class that allows me to do this; the class is "java.lang.String" and the method is "public int indexOf(String,int)"
Is there something equivalent in CVP 7.0(1)?
thanks

Thanks again for your help. This is what I ended up doing:
This configurable action element takes a string seperated by two "|" (123|123456789|12)

Is there a market for Java 3d?

Hi, i'm just about to finish college this year and have worked with lots of programming languages during my time in college but found java to be the most interesting... After a while i got into making games in java with the help of the java 3d api. I'm interested in going into this market when i finished colelge but i was just wondering...
Is there a future for java 3d in the games development market?

That was 75% of the reason. It was waaaaay overpriced.
The ports being on the bottom, where no one could get at them, was another big reason it was not accepted by the public.
I am among those who have been pushing for a desktop system with a mini-like footprint, but imac-like performance -- but I've been advocating this since before the Mini existed.
One idea I put forward in my Mac User Group's newsletter was for a machine just slightly taller than a mini that docks into a cinema display-type monitor. This would allow apple to sell them together for an imac experience, or separately.
Regardless of whether or not they did the docking thing, this is the computer system that could really bring about great Mac acceptance in the corporate world. But of course Apple ignores that space and seem deaf to the needs of industry.

Is there any method in Java to convert from system time to variant time?

From MSDN:
A variant time is stored as an 8-byte real value (double), representing a date between January 1, 100 and December 31, 9999, inclusive. The value 2.0 represents January 1, 1900; 3.0 represents January 2, 1900, and so on. Adding 1 to the value increments the date by a day. The fractional part of the value represents the time of day. Therefore, 2.5 represents noon on January 1, 1900; 3.25 represents 6:00 A.M. on January 2, 1900, and so on. Negative numbers represent dates prior to December 30, 1899.

There is a new Java update availible, however when i go to software update the download doesnt appear. someone please help!

I know that there is a new java update available because when i go to java's website it tells me to go apple-software update because i have a macbook. however, when i do so it tells me all my software is up to date. Any help is much appreciated.

Java support is changing. Currently Apple is working on Java 6 for Macs and regularly releasing updates. There is a developer preview available but this is not recommended for regular users as it may contain unexpected bugs. The latest version for regular users is java version "1.6.0_24".
Java 7 is currently under development, in a community effort led and co-ordinated by Oracle. This effort includes Java for Macs. Once this happens it might be that you'll no longer get Apple Mac Java updates from Apple, but instead you'll get them from the same Java website as Windows and Linux users. Whatever happens, Java will continue to be supported on Macs well into the future.

Is there a Zen to Java programming?

As a programmer/ tech writer, I�m sort of envious of luxuries available to theoretical physicists who may contemplate such mysterious and exciting things as Heiseinberg Uncertainty Principle or wave-corpuscular dualism of elementary particles. However, are physicists the only hi-tech community that is permitted to enjoy surfing the Zen paradoxes abound in the world around? Are we computer people deprived of the like delights just because computing is so deeply rooted in Aristotelian and Boolean logic? I hardly think so. Zen (one may add Tao) logic is universal, and although we so strongly tend to employ patterns of our dreary �either-or� thinking while programming artificial things, these things, quite interestingly, happen to be not exempt from the Chaotic Beauty of the Natural World. In a word, Complexity (can one question complexity of modern computing?) ever meets Chaos. And an encounter with Chaos, paradoxically, expands our understanding of Order; or rather force us into accepting a sort of Another Order that underlies seemingly chaotic processes we observe. Further, I argue my thesis.
Recently, I�ve pondered on tricks of object-oriented programming (OOP). Much was said about �more human-oriented� approaches available with OOP, which allow the programmer to enjoy a higher level of abstraction in comparison with traditional procedural methods that chain the poor developer down to a controlled flow of bits deep inside the machinery. Yes, as for me, systems design and programming in C++, Smalltalk and Java delivers more sense of �soaring above� than it does in COBOL. In other words, programming in Java appears to be a �more human� way of thinking. However, what do we understand saying �more human�? Here we need to be slightly technical. In essence of OOP lies the concept of object, which may be understood as an entity modeling a real world situation. One may announce that a Java programmer thinks in terms of real world proceedings, delivering his or her understanding of the processes by means of the quite abstracted technical language (code). As far, it sounds quite human, and it is so. And here again we can find, not surprisingly, the deep-rooted patterns of rational �either-or� logic. Object is thought of as static entity, and of course it is static in a technical sense. It possesses such qualities as state and behavior, changeable only within predefined limits. Also, object may be thought of as static because it represents a fixed (constant) set of variables (attributes) and subroutines (methods). Of course, objects provide only a degree of abstraction as to what we understand as a real world situation. However, at the same time they most definitely cannot be perceived as static entities because of dynamic nature of the computing process. In essence, computing is all about data processing, or performance of logical operations on variables stored in memory (the process was mathematically modeled well before the advent of computer as the famous Church-Turing Machine). More simply, there can be nothing static in computing at all, because computation is always a process. So, musing on the nature of objects in OOD&P, we encounter a highly sophisticated logical system presenting the following set of choices: (1) object is either static or dynamic, (2) object is both static and dynamic, (3) object is neither static nor dynamic. As we see, the two latter options sound absolutely Zen-like while the former characterizes the good old Western Aristotelian logic. This is the point where Complexity (of computing) meets Chaos, as it is thought of by Western mind-view, i. e. absence of logical consistency and determinism. It�s obvious that in OOP we cannot perceive object in other way than embracing an advanced sort of logic, so characteristic to Eastern thought. If we understand object as a real world entity, we are entitled to see it as a Zen entity either, which can be described only in the conformable logic system.
[I�ve patented it as Bojenov Uncertainty Principle in OOP. Of course, I�d be curious to hear from fellow Zen programmers and find out their opinions on the matter, via e-mail preferably.]

You should spend some time around actual Physicists. You'd realize that a very small portion of Physics involves irrational, or imaginative thought. That instead a small portion of it is the imagination, and a larger portion is the execution to test the theorys produced my imagination. And this execution is MUCH less imaginative then anything. Alot of Physicists spend a great deal of their time programing at computer terminals making mathematical models of their data, most of them using far less conceptual models that are afforded to us computer programers these days.
Alot of the Physics department is bent on still using Fortran. They're having a hard time getting them to convert to using C rather then Fortran, yet alone Java or C++. And I'm certain you can agree that these languages allow alot less room for imagination then does Java. You should probably work on introducing these traits you think so highly of the Physics community as having, to the physics community. And once they've fully learned to appreciate them, then maybe you can work on expanding them to the Computer Science community as well. You should realize as well that most Physicists, are also Computer Scientists.

Is there a forName() for java.lang.reflect.Type?

Is there an equivelant to Class.forName() for all types?
For example:forName("java.util.List<java.lang.Sring>");
//or
forName("int");Such a method would return a java.lang.reflect.Type, instead of return a java.lang.Class
See also
Field.getGenericType()
Method.getGenericReturnType()

incidentally, getGenericType() will give you the
generic type of the member being examined, not the
parameterized type.
that is, if I declare a method like this:
public <T extends MyInterface> T getStuff() {
}I won't be able to reflectively find out what types
of T are being used at runtime, only that it's of
type 'T'. of limited use really
Java's implementation of Generics isn't as good as it
could be, mainly to maintain backwards compatibiityYou are right in that case because that is not a ParameterizedType that is a TypeVariable.
Type can encompass both Types.

Is there a deconstructor for Java

I know in C++ they use the name of the class with a tildy in front of it (~Class) for a deconstructor and VB has a method as well but I didn't see any way for Java to do this. Is there a way?

The thing you can't invoke (in theory) is garbage
collection. You can try with System.gc()twice
(I'm under the impression this works), or failing
that, you could cause an OOM exception, whichwould
force a GC of collectable objects.That is not the same as calling delete on a
pointer/reference. And calling System.gc to allocate
an object should never be done. There are a bunch of
articles that says why calling System.gc is bad.Where did I say it was good?
You can even call the '.finalize()' methoddirectly,
of course.That won't free the memory.
Sorry, but you are wrong :)Sorry, you misunderstood. Read again. I never suggested anything about freeing memory. Read your own post, and consider my response...

Is there a mechanism in Java similar to Properties in C#?

A friend of mine is working on a project in C#, and periodically I've been examining his source code, and commenting on how similar the syntax and programming style seems to be to Java. Recently my friend asked me a question about 'Properties', which I wasn't familiar with. So I found a few websites that describe how Properties work in C#, and now I'm wondering if there is anything similar to Properties in Java?
In case any of you are curious, this particular website has a pretty straight forward explanation
http://www.c-sharpcorner.com/UploadFile/rajeshvs/PropertiesInCS11122005001040AM/PropertiesInCS.aspx
I'm not advocating C# or trying to start an argument about the pros and cons of Java vs. C#, I'm just wondering if there is an analog to properties in Java, or if there's been mention of doing so in future releases.

For good or bad, even though Java and C# are very similar in style, C# is way ahead featurewise.
