Hi,
I have a list of binaries written in java, ada,C, python and I want to execute them.
How to do that ?
Is there any JVM binding to those languages ?
Thanks for your answers
Hi,
Today I got this question for which I think I answered very bad. I said stream is a data that flows and reader is a technique where we read from that is a static data. I know this is an awful answer, so please provide me the crisp difference and definitions between these two with example in Java.
Thanks.
Hi Folks,
I created an java apllication. i created the Excecutable jar and Exe files for my application. But it cant be run at a system which not installed computer. How to do it? Is there any possible to configure the JRE in the EXEcutable jar or Exe file itself? Any Idea?
I would like to add the ability for users to telnet into my app where by they can type in commands etc. I would like a simple Java Telnet server whereby i can provide the authentication strategy.
Is there a default timeout for threads waiting on a synchronised method in Java? Some threads in my app are not completing as expected. Is there anyway to check whether threads have died as a result of timeouts?
Is there any good reason to avoid unused import statements in Java? As I understand it, they are there for the compiler, so lots of unused imports won't have any impacts on the compiled code. Is it just to reduce clutter and to avoid naming conflicts down the line?
(I ask because Eclipse gives a warning about unused imports, which is kind of annoying when I'm developing code because I don't want to remove the imports until I'm pretty sure I'm done designing the class.)
How to sort a map(?,B) on the values in Java with google collections ordering function, if B is a class, which has a field of type double, which should be used for ordering.
I was wondering how Java sorts items in the Map (HashMap or Hashtable) when they are added. Are the keys sorted by the hashcode, memory reference or by allocation precedence...?
It's because I've noticed same pairs in the Map are not always sorted in the same order
My multithreaded Java program crashes because it runs out of heap space and I don't think it should. Assuming the culprit is unintentional object retention, what's a good free tool to investigate what objects are being unintentionally retained?
My IDE is Eclipse.
Have a Map which contains objects that I want to keep in sync across multiple servers, such that if objects in the map are created, deleted, or modified - this is reflected immediately (ie. within a second or two) across all servers, in a way that can potentially scale up to tens of servers.
Is there a lightweight open source Java tool that can do something like this? I'm aware of Terracotta but it is rather heavy weight for what I need.
I asked a question about Garbage Collection in Java in this topic.
But the answer I got, gave me another question.
Someone mentioned that classes can be collected by the garbage collector too.
Is this true?
And if it is true, how does this work?
I want to access a MySQL database from Java, but remote connection is disabled by the host.
So I will send the data to PHP and then PHP will locally access the database.
The data is pretty big (about 2~4kb)
I've never done this before.
What should I do?
I want to cut the svn/cvs recods in pieces and then put in to database. After that i can make use of those data easily.
Any java function can get out the record? and How?
If possible, please provide a example. Thank you.
Hello, I am developing a new Java Desktop app. Something like a media player. I want to load most of the resources in the background when the computer starts up. But the users can turn this option off form within the app or using some other utility. So, what I want to do is if a ban instance of the app is already running and the user starts the app again then I can communicate with the already running instance so that it can launch a new window?
I just want to play a very simple, straight forward note by giving my computer a certain frequency as an integer, and from there I can figure out how to make it play the note longer or shorter. It does not necessarily have to come out of the actual sound card - if it's generated and output by the internal speaker that's okay.
I looked at the midi libraries that java has included, and they are way more than what I want to do. This just needs to be very basic.
I'm designing a web application.
I was wondering if it was feasible to design a php front end (using some php framework e.g. CakePHP), which stores and retrieves data to display to the user.
Then develop a java backend which listens to the database for changes, and depending on what was changed, performs some actions and updates the database.
Any thoughts on this type of implementation would be appreciated.
I have two pieces of text. I would like to make a word-based diff between them (like whe unix utility wdiff does) but with more information in the output (I mean, the character's posizion where the added/delited word starts).
I need to do this in Java, so a simple output of the differences (like wdiff) doesn't suite for me: I would like to manipulate objects representing differences.
what java method takes an int and returns +1 or -1? the criteria for this is weather or not the int is positive or negative. I looked through the documentation but i'm bad at reading it and i can't find it. I know i've seen it somewhere though.
