Whats the use of having two Date classes?
I'm going to use Selenium RC to replay some tests for a website. I want to kickoff those tests from a Java test framework so that I get nice reports how many tests failed, etc.
Which java test framework should I use? Is JUnit the preferred framework for this purpose?
the issue i mentioned in this post is actually happening because of cross threading GUI issues (i hope).

Just started to getting familiar with graphics in Java.

Looking for methods like putPixel, lineTo, etc.
After some googling an obvious answer or starting point for a Java IRC bot has not presented itself, my question; is there an existing framework to help me do build an IRC bot? Failing that, is this possible using Sockets in Java to do this and has anyone seen an example around the web?
cheers guys.
A little help from you all...
I was trying to convert a simple java program into jar but nothing seems to have happened.
I have 2 files: Tester.java , Tester.Class.
Then I used this command line:
jar -cvf Tester.jar Tester.class
The .jar file was created but nothing seems to work.
What did I miss?

Hi!
I'm a c# guy giving Java a try .. so how would I do the following in java.
in C#
public T create_an_instance_of<T>(){
T instance = default (T);
// here's usually some factory to create the implementation
instance = some_factory.build<T>();
// or even..
instance = some_factory.build(typeOf(T) );
return instance;
}
Can any one clear me exactly what happend when we do import statement in java files. does it inscrease the size of file if we add more and more java classes.
why we dont use classloader for the same
and what are the restrictin for importing.
I encrypt my message with a symmetric key and the symmetric key itself has to be further encrypted with different RSA public keys. When I tried to implement the above I got the following error:
javax.crypto.IllegalBlockSizeException: The input was invalid: Invalid input length.
at com.rsa.shareCrypto.j.hD.engineDoFinal(Unknown Source)
at javax.crypto.Cipher.doFinal(Cipher.java:2087)
at wrap1.main(wrap1.java:69)
Is there a way to solve this problem ?
I'm writing a .NET application that will make an RPC call to a Java application (via a message queue). The data sent in both directions will be large arrays of floating-point numbers. What is the best way to serialize them to send them across the wire? I'd like something more compact than text, but architecture-independent as the server may not be an x86 machine. The Java application can be changed as needed.
Java is not my main programming language so I might be asking the obvious.
But is there a simple file-handling library in Java, like in python?
For example I just want to say:
File f = Open('file.txt', 'w')
for(String line:f){
//do something with the line from file
}
Thanks!
hello fellow java developers,
Im trying toget the System.getProperty("os.name") of my own machine. I am running a java application directly from the machine from within eclipse.
My machine is "windows 7"
the returned value is "windows vista" ! Seems wrong, very wrong. and yes I am sure that I am running the app on a windows 7 machine...
Any ideas as to what is going on here?
Hi all,
I've a scenario where my java program has to continuously communicate with the database table, example my java program has to get the data of my table when new rows are added to it at runtime. There should be continuous communication between my program and database.
if the table has 10 rows initially and 2 rows are added by the user, it must detect this and return the rows.
My program shouldn't use AJAX and timers.
Please Help.
I have a object store in Java. My C program stores data (in form of char array) in java. Now I wish to retrieve data from my store. I cannot find any function call that returns me an char array. How can I do this?

I'm wondering if it would make sense to do some low level or OS stuff(a project) using Java. Reason why I ask is because I would like to expand my knowledge in Java and I'm into doing stuff like file compressor, bulk file renamer, etc. Are there any examples out there that I can look at or play with? Or should I just be using C or C++ instead?
Thanks!
In Java how can I take the data of my file on my display screen?

I am developing a Java application with MySql as the database. I have to dump the MySql database from my application periodically(let say every day at 10 a.m.) and I have written a batch (.bat) file for dumping the database. The batch file is working fine, but the problem is that it is asking for password each time during its execution.
Is there any way to dump MySql database without prompting for password and achieve it from Java application periodically?
Many of today's programming languages are based on C; like C++, C#, Java, Objective-C. So could I call a C method from C++ code? Or call C from Java or C#? Or is this goal out of reach and unreasonable? Please include a quick code sample for my and everyone else's understanding.
So, I am just starting Java and, even though I have looked in some question about it here at stackoverflow.com and elsewhere, haven't been able to find a straightforward answer to why isn't possible to overload a function just by changing the return type. Why is it so? Will that provably change in a future version of Java?
By the way, just for reference, is this possible in C++?
Thanks.
Do you know a Java library to render static SWF file (no animation, just raster and vector images on a canvas) to PNG? I know swfrender (a part of swftools) but I need java, not C.
