Hey,
I want to measure thread execution time in Java. Now I'm monitoring thread start and end times, but I think it's not so accurate because thread could be suspended during it execution.
Is it possible to define array in this way in JAVA, otherwise are there an alternative close this definition?
private final int CONST_0= 0;
private final int CONST_1= 1;
private final int CONST_2= 2;
private final int CONST_3= 3;
private final String[] CONST_TXTRECORDS = new String[]
{[CONST_0] = "test0",
{[CONST_1] = "test1",
{[CONST_2] = "test2",
{[CONST_3] = "test3"};
I have an web application written in Java, and I have a thread-pool.
The application is huge, and I cannot make major changes, for example, I cannot change log4j.
I am executing a batch process in the thread pool, and I want to log everything that goes is executed to execute that process.
There will always be just one thread active in the thread pool.
Any ideas of how can I do that?
Hey guys,
I am working on a Natural Language parser which examines a sentence in english and extracts some information like name, date etc.
for example: "Lets meet next tuesday at 5 PM at the beach."
So the output will be something like : "Lets meet 15/09/2009 at 1700 hr at the beach"
So basically, what i want to know is that is there any framework or library available for JAVA to do these kind of operations like parsing dates from a sentence and give a output with some specified format.

I am trying to dislplay a kannda character in a Java app.
String fonts[] = ge.getAvailableFontFamilyNames();
This shows that there is a font family by name "BRH Kannada"
Font f = new Font("BRH Kannada", Font.PLAIN, 20);
and then I do
button.setFont(f);
now when i set the button text, I have to ideally get the text on button to use the BRH kannada font.
However, what and how should I give the string as?
When I do the following in Java:

I'm looking for a lightweight java reporting engine to be embedded in an applet application.
My first option was Jasper Reports, but the jar is over 2Mb, a little too heavy (and too bloated) for my needs. I don't know if there is modular jasper distribution, with funcionalities split in several jars (like html rendering, pdf, excel, compilation, runtime, etc).
I need to preview the report using Swing and print it. PDF export is a plus.
When I use the default java locale on my linux machine it comes out with the US locale settings, where do I change this so that it comes out with the correct locale?
I'm looking for a Java ORM that works from database reflection - I need to just point it at a DB, and start being able to walk through the entire set of tables, etc.
Ideas?
Usually when I'm typing a Java import statement in Eclipse or otherwise referencing a class via the packages that it is in, Eclipse shows a context menu with a list of all classes within that package. There have been several times, however, that it would only shows subpackages within a package and would not show classes within that package.
Does anyone know why this is? It sounds like a setting/preference was changed, but I never knowingly changed anything related to this.

Hi,
I found Facelift which can basically generate html headings as images (with "nice font") on the fly. Does something similar exist for Java (couldn't find one myself)?

Hi all,
I've been programming in Java for a few courses in the University and I have the following question:
Is it methodologically accepted that every class should implement an interface? Is it considered bad practice not to do so? Can you describe a situation where it's not a good idea to use interfaces?
Thanks.

I was planning to write an app which uses URLConnection on a server equipped with Comet but I doubt if that would work as the client requires a JS to be invoked and URLConnection is not a browser..
What is the best way to push instead of using a proprietary client-server approach?

I have to convert an incoming String field into a BigDecimal field that would represent a valid amount of money, for example:

BigDecimal valid_amount = convert(amount);
print(valid_amount.toString())//1000.00
What is the right API to use convert a String into a valid amount of money in Java (eg: apache commons library)?
Thanks in advance,
