How to find file type (Binary/Ascii) using Java IO

Hi
I want to find whether the file is binary file or not.
Can any one please help.
Thanks,
Joy

I'm no IO expert, but aren't all files binary?Yes.
I think what the OP is after is how to tell if a file contains only characters (e.g. ASCII characters). This can be done by reading the file and checking if every byte is a valid ASCII character more or less. An example would be limiting byte values to 9 (tab), 10 (LF), 12 (FF), 13 (CR), and 32-127.

How to find Number of working threads using java executor framework

I'm creating a java thread pool using java 1.5 executor framework.
private ExecutorService executorService = Executors.newFixedThreadPool(threadPoolSize);
public <T> Future<T> submit(Callable<T> task) {
return executorService.submit(task);
}Now I want to get the number of working thread at runtime. Is there any java api available to do this using java 1.5 executor framework?
Thanks,
Arpan

If the ExecutorService you are working on is a ThreadPoolExecutor then you can use ThreadPoolExecutor#getActiveCount() to get the count of threads actually running tasks. There is no such method on the ExecutorService interface though.

Which file type should I use and how I use it?

Hello!
I need to create a file with some data that has been inserted manually.
In this file, for example, there are:
ProjectName1: string1, string7… string10, date1
ProjectName2: string11, string15… string20, date2
ProjectNamek: string 100, string 116 … string 140, date1
I know only one thing: one of the strings.
What I need to find in the file:
I need to find the string at one of these rows and get its ProjectName and date.
For example: if I have string15,
I should find string15 in the file, and get its ProjectName and date:
ProjectName2, date2
Which file type should I use and how I use it? What is the best solution?
Thanks!

(ie:
1. ProjectName always starts the line and ends with a ':'.
2. The rest of the strings on the line are separated by ", " and will never contain ", "
you might also want to have a look at String.split().

How to find out names of reports using a particular view

hi guys,
i am newbie here, i jsut want to know how to find out which reports are using a particular view
many thanks in advance for your help

If you go to the Properties for the Folder in Discoverer Administrator, there is a Dependents tab that should list any workbooks using the folder. This only works for workbooks saved to the database, so won't help with any created using Discoverer Desktop. If you are gathering statistics and have the The Discoverer V5 EUL business area and its workbooks installed, it can tell you about Folders Used as well. It contains information about queries run whether the workbook is saved to the database or to the file system, but wouldn't contain inforamation about workbooks that had been created but not run.

Where is "save as" or how to change file type in Preview in Lion?

Where is "save as" or how to change file type in Preview in Lion? I used to use Preview to change quickly change a lot of PNGs to either JPEGs or PDFs but with the introduction of versions auto save etc there no "save as" in the File menu. Any suggestions how to get this functionality back or how to get around it within OS X (no Photoshop etc)?

Just wasted 15 minutes looking for that. What's wrong with Save As?

How to find out which keywords were used to create a smart album?

Hi,
I actually have 2 questions;
a) Short of scrolling down my very long list of password on the HUD - is there an elegant way to do it - How to find out which passwords were used to create an existing smart album? It's a recurring challenge for me.\ 'cause I like using smart albums, but once in a while need to check or chane the passwords.
b) With annoying regularity when I try to get to this forum and choose Aperture, I get the following message - in pink, no less: It appears you're not allowed to view what you requested. You might contact your administrator if you think this is a mistake.
Any clues?
Thanks guys,

Raphael,
that message may occur for four reasons at least:
Most frequently, when you are using an outdated link to a post that no longer exists, for example from an email notofication. Sometimes our community host will remove posts, that are in violation of the terms of use: see:
Apple Support Communities Terms of Use
Or you are using the edit button or a bookmark to an "Edit" window, after the fifteen minutes allowed for editing are up.
Or you want to view a page in a restricted section of the ASC - soem perta are only open for members of level 6 or higher.
Or it is one of the unexplained problems with the forum software right now.

It's a recurring challenge for me.\ 'cause I like using smart albums, but once in a while need to check or chane the passwords.
I really like Kirby's suggestion with the IPTC rule Keyword is. This is very useful for smart albums global to the library.
Frequently a different approach helps for my smart albums. Many of my smart albums are local to projects or folders. In this case the smart HUD will only show those keywords that have been used for the images in the selection. So if I only have tagged the images with the keywords "birds" and "slideshow", the smart settings HUD will only show these two keywords and the list is very short.
My Keywords HUD, is organized hierarchically; this way I can collapse large sections at once, and it is easier to focus on the keywords needed for a specific task.
I use the search field in HUD a lot, to filter the set of keywords shown.

How to find out if I am using a 32 bits or 64 bits version of JRE?

How to find out if I am using a 32 bits or 64 bits version of JRE?
If I have 2 instances of Java installed in 2 seperate directories, one 32 bits and other 64 bits on Linux. How do I identify which directory holds which version?
Is there any command that can output this info?
Regards,
Billamama

With a Sun JDK or JRE, you can use java -version:
$ java -version
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Server VM (build 1.6.0-b105, mixed mode)
... switch to the 64-bit JDK ...
$ java -version
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) 64-Bit Server VM (build 1.6.0-b105, mixed mode)
The last line says "64-Bit."
