Hi!
Is it possible to set 'clipping bounds' in JOGL? Like in Java/Swing i would like to set clipping bounds and all drawing/rendering outside those bounds would be ignored.

Hi,
there is a poker-system in java, that uses Collections.shuffle() on all available cards before the cards are dealt.
So a collection of 52 cards 2-9, J, Q, K, A in 4 types.
After that we Collections.shuffle().
The problem is, that it seems (until now we didn't have big statistic, it's possible that we only see a lot of statistic inferences), that the algorithm is VERY unclearly.
So, is Collections.shuffle() okay for a poker algorithm?
hello all.
I have an array:
int test[]={10212,10202,11000,11000,11010};
I want to split the inetger values to individual digits and place them in a new array as individual elements such that my array now is:
int test2[]={1,0,2,1,2,1,0,2,0,2,1,1,0,0,0,1,1,0,0,0,1,1,0,1,0};
How would i go about doing that? I'm doing this in java.
Thank you.
How can I see in Java if an Object is an array without using reflection?
And how can I iterate through all items without using reflection?
I use Google GWT so I am not allowed to use reflection :(
I would love to implement the following methods without using refelection:
private boolean isArray(final Object obj) {
??..
}
private String toString(final Object arrayObject) {
??..
}
BTW: neither do I want to use Javascript such that I can use it in non-GWT environments

I´m developing a Java solution for manage an iTunes Library (ITL file). The ITL format is a propietary one.
I'm looking for an implementation or a documentation about ITL format but Google can't find anything useful.
Does anyone have experience about that? Where to find more information?
Thanks in advance.
Hi,
As part of a homework assignment, I have to program a simple chess game in Java. I was thinking of taking the opportunity to experiment with recursion, and I was wondering if there's an obvious candidate in chess for recursive code?
Thank you,

Browser plays youtube videos with following code.
I tried downloading from URL http://www.youtube.com/v/OdAE3cWlmHw
but it is not returning video bytes.

I don't understand Access Modifiers in OOP. Why do we make for example in Java instance variables private and then use public getter and setter methods to access them? I mean what's the reasoning/logic behind this?
You still get to the instance variable but why use setter and getter methods when you can just make your variables public?
please excuse my ignorance as I am simply trying to understand why?
Thank you in advance. ;-)
I came across this questions on one of the online Java Tests. The options were 4,5,8 and any number of times.
I have only used one inner class, but have never tried multiple ones. I was wondering if anyone knows the answer.
In Java, I may have a class, for example, "utility" ....., and I have a static method called "changeToCapitalLetter", so , I can do something like this:
Utility.changeToCapitalLetter(String myString);
How can I do the similar thing in Objective C? thz a lot.
Dear all,
I am new to JPA, I used to used prepared statement in JDBC. Is there alternative to be used within JPA ? as there is a query which I call frequently
see this for info about prepared statment http://java.sun.com/docs/books/tutorial/jdbc/basics/prepared.html
thanks in advance,,,
I'm practicing my knowledge of ADTs by implementing some data structures, even if most already exist. With Stacks, a lot of books and other documentation I've read talk about the stack throwing an error when you try to add an element but the stack is full. In a java implementation (or any other), should I specifically keep track of a maximum stack size (from constructor), check to see if that size is reached, and throw an overflow exception if it is?
Or is not such a big deal?
<body>
<form action="<%= blobstoreService.createUploadUrl("/upload") %>" method="post" enctype="multipart/form-data">
<input type="file" name="myFile">
<input type="submit" value="Submit">
</form>
</body>
the above code throws a java.lang.NoSuchMethodError on compilation.I can't understand and what is blobstoreService in the above code ?
Examining the attributes of UTF-16 and UTF-8, I can't find any reason to prefer UTF-16.
However, checking out Java and C#, it looks like strings and chars there default to UTF-16. I was thinking that it might be for historic reasons, or perhaps for performance reasons, but couldn't find any information.
Anyone knows why these languages chose UTF-16? And is there any valid reason for me to do that as well?
Hi,
I have been working in Java for the last 6 months and have been using Hash Maps
What is the basic idea of a Hash Map ? I am using it as it easy for me to store so much data with direct key references rather than having to iterate through an arraylist ?
Where is the power of Hash Map seen ? What is the scientific idea behind this data structure ?
I have a xml document. I know the index where i need to insert the new node. The index that i have is the position considering only the text nodes and ignoring the element tags. Is there a java api to seek the index in a xml knowing the position relative to the text nodes alone and insert a new node in that position?
At first I want to let you know that this question is not related with What is native implementation in Java. I got many useful information from that thread.
I want to know that are the codes of the native implementations available? I have jdk source code but I can not find the native codes for System.currentTimeMillis or Runtime.getRuntime().availableProcessors() or other native method.
Thanks and regards.
I'm using libsvm and the documentation leads me to believe that there's a way to output the believed probability of an output classification's accuracy. Is this so? And if so, can anyone provide a clear example of how to do it in code?
Currently, I'm using the Java libraries in the following manner
SvmModel model = Svm.svm_train(problem, parameters);
SvmNode x[] = getAnArrayOfSvmNodesForProblem();
double predictedValue = Svm.svm_predict(model, x);
i am writing stored procedures in MySQL that return values;
CREATE PROCEDURE getCustomerById (id int)
BEGIN
SELECT *
FROM customer
WHERE customer.id = id;
END;
and i get the error that the results cannot be shown in the given context.
after some googling, i think that i need to set the flag "CLIENT_MULTI_RESULTS" - i am connecting the database from JDBC using a java app, but cant find where to set it!
any suggestions?

I want to use EC2 for some reasons and EC2 provides both windows and linux deployments, but linux is much cheaper (linux reserved instances are approx. %63-%85 price of windows ones and spot instances are %50 cheaper for linux). I need a type safe lang and mainstream platform and I prefer to use .net/c# stack (but not mono for some reasons), but in this situation java seems a better fit for the future (when ec2 instance counts begin to increase). So, is it worth to use .net ?
best regards,
Hi,
I'm planning to modify some bits in the platform/frameworks/base project in Android Donut r2. The modifications are very small and go into java packages android.graphics and android.text (the API isn't affected).
What jar libraries do I have to copy from the recompiled platform? the modifications are small and I don't want to replace the whole system.. I'm trying to replace specific jar libraries.
Thank you
