Programming :: Java: Referencing Image Within Package
Jan 30, 2009
I am running into a small bit of difficulty with images I want to use in a Java program, keeping them bundled with the program in a JAR file and accessing them within the package.For those who are thinking it, this is definitely not homework.In my program, I have several images I would like to use on buttons on a toolbar.I have Googled, and I found something that comes close, but it deals with fetching images from a URL - nothing that deals with local files, more specifically, local images kept inside of a JARchive.

I am learning some Java programming, and I've run into a problem. I am trying to set a background for JFrame, so that I can put text and buttons on it. I've tried searching the internet, and the only code that I found that was a full code (I lost it, and don't remember the link) had so much other stuff, such as text and buttons, that I couldn't find the part I needed.

i am a complete newbie in java. while dealing with packages i faced the following problem. I created a file named "CreatePackage"
Code:
package lobkush;
public class CreatePackage {
public CreatePackage() {
System.out.println("you are presently under package named "lobkush" ");
}
}
after this i created a folder named "lobkush".I also compiled the source file and placed the .class file in the corresponding directory.
Now to test it i created another java file. This is where the problem arises.while importing the class file if I write:
Code:
import lobkush.*;
the compiler shows an error
but if I write
Code:
import lobkush.CreatePackage;
no error is shown and the .class file generated.

I'm a 1st-year CS major and am new to Java. I had a question about importing packages. As I understand it, when you use a wildcard when importing, it will import the classes within the package specified before the asterisk, but none of the subpackages in the specified package.is there a way to include all classes and subpackages recursively with a single line, instead of doing:
import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
As I understand it, it doesn't actually cause any bloat in your bytecode, so if it can be done, would there be any disadvantage?

I have some strange behavior in Latex. I have added labels to all of my tables (currently there are 3) and my figure (currently there is only 1). So far I only notice this behavior with tables, though it may happen with figures as well...I will have to add another figure to test that.However, what is happening is that my list of tables is correctly generating the numbers of the tables (which are 3.1, 3.2, and 4.1). In the resulting PDF document, the tables have the correct numbers in the captions as well. The odd thing is that when I attempt to reference them using ef, it is printing the Chapter.Section[.Subsection] number the table is located in instead of the table's number itself.Right now I have two tables inside of Chapter 3 Section 3. They are as follows:
Code:
egin{table}[htdp]
egin{center}
[code]....

I've got a situation. I'm having GNU bash version 3.00.16(1) on Solaris 10. I need to declare an array say arr1 which will be populated by an output of a command.
declare -a arr1
arr1=( $(/some/command) )
Supposing it will eventually (after executing the command) have element values as -
arr1[0]=1234
arr1[1]=5678
arr1[2]=7890
Now, I need to declare another set of arrays, one for each of the element values above - e.g.
declare -a arr1_1234
declare -a arr1_5678
declare -a arr1_7890
And I also need to populate elements of each of above 3 arrays with output of another command in a loop. So, these arrays will hold values something like -
arr1_1234[0]="abc"
arr1_1234[1]="def"
arr1_1234[2]="ghi"
arr1_5678[0]="jkl"
arr1_5678[1]="mno"
arr1_5678[2]="pqr"
arr1_7890[0]="tuv"
arr1_7890[1]="xyz"
arr1_7890[2]="aab"
I'm able to declare and populate arr1[*]. My question is how do I declare, populate and print the subsequent arrays and their elements?I am feeling rather thick to get this working.

I have just exported 3 png files out of gimp for a html document I'm working on right now, and they are all almost the same, except I need each to load when the user does something. So the first image will display on the page, and when a user puts their cursor over it, then it will load image 2. When they press it, it loads image 3.

I thought I knew what I was doing, just a minimal install of slackware 13.1 for a game server (minecraft), but it seems I missed java or something - I get the "command not found" error. gcc-java is installed. What package did I miss/what series is it in? Does it have any dependencies?

Groovy is an object-oriented programming language for the Java platform. I do not have experience in Java, only perl and shell scripts. Recently I have been asked to maintain a software written in groovy (also to make enhancements). So can I learn groovy without knowing java language. or isit I have to learn java before venturing into groovy.

I'm trying to install Open Rocket : [URL]. I don't think I have java installed. I went to software center and tried to install "OpenJDK Java 6 runtime" and it says package dependencies cannot be resolved. I tried doing sudo apt-get install through terminal and it was dependent on a long list of things:
openjdk-6-jre
openjdk-6-jre-headless
tzdata-java
tzdata
I tried to sudo apt-get each one and it led me down the list like that to a dead end.

This is on a cloud instance of maverick 64bit.In using cloud init to install a package (also does not work manually) I receive the following error.issuing an update with --fix-missing also does not work. I do notice, however this is trying to hit ec2.archive. For iperf I don't know that it needs to be ec2 specific. To my knowledge this worked a few weeks ago. Also, where it is easy enough on a Desktop version of maverick to simply switch sources for the upgrades/updates I have not found how to specify a new url (i.e. Duke University vs. MIT) The repositories I am happy with just the location of the repositories.On this particular cloud image is it even safe to leave ec2 as it is a specialized stripped down image.

So after much intense reading of linux documentation and posts I can't find an answer to my question. Maybe someone can help.I am trying to access a kernel symbol that isn't exported (the symbol exists in /proc/kallsyms but not in Modules.symvers). Is there a non intrusive way (by avoiding compiling the kernel with CONFIG_KALLSYMS and parsing /proc/kallsyms in my LKM) to reference kernel symbols that are in /proc/kallsyms and not in Modules.symvers i.e. not exported symbols.

I'm building a certain RPM package that must require an old version of that same package in order to be installed/upgraded. Is this possible?
For example:
For a package foo v5, somewhere in the spec file:
"Requires: foo >= 4"
I'm declaring this on the Requires tag of the spec file, but when I try to install or upgrade the package (without having the previous required version installed) I get no dependency error! As for other dependencies it all works fine. If, instead, I create a package named "bar" that "Requires: foo >= 4", when installing I do get the expected dependency error. I'm thinking it's not possible to require an old version of the same package.

today I've tried to activate nautilus-converter-image package. due to some package's requirement I've thougth download last release about glib, pango and nautilus... trying install them I've got some errors (here, I've also give an ldconfig command) so at the end I've resigned and decided didn't install nautilus-converter-image. Thinking about replace original package I've reinstall the original. but after reboot when I clik "computer" o "network" icons in nautilus I get an error message like this.(translating) <Nautilus can't handle place "Computer" or "network">
Also I've seen when insert a media usb storage, I can't see in nautilus that device mounted, and also in /media is not present...Ok I know I has been too much superficial... but now It's really annoying problem..

This is supposed to be possible right and better than naming each single cell?How do you do it?Also, maybe my approach is wrong as it's going to lead to a very big nested IF statement.There is a list of numbers which are price ceilings and another list of numbers containing the fees applied to these. I want to a formula that checks the item price against the ceilings and if it's less than or equal to that ceiling uses the fee in the adjacent row (which is the other data range).The only way I know how to do this is a big nested IF statement but does anyone know better?

In light of my previous achievement in wireless networking, I've decided to create a larger issue for myself to solve. Which hopefully I can get some help with. Because my system is totally kisspoped up, for those of you who get what that means. I was trying to install GRUB via the .txz package and it created a mirrored image of the /boot folder. Which for some reason contained the / folder. Which in turn held /boot and all the other folders / is expected to contain.
Now, trying to remove the extra /boot folder proved difficult, but once I finally was able to figure it out, I remembered I could removepkg and that would probably mend the situation. However, I was already 20-something percent through moving the files to trash. Now when I checked /, /boot was gone from there. Along with various other folders. SO! Apparently the /tmp/boot folder created was in reality the /boot folder, albeit in the wrong place and having the wrong contents. Somehow, one folder existed as two different versions of itself at the same point in time. Much as a Time Lord might. Deleting one made the other vanish with it.
Good news:I removed it via Thunar and it should be in the root user's trash /home and some other folders had yet to be trashed when I hit cancel, so I can still use some things Bad news:I never ran X as root, so I don't know if it HAS a trash folder I can only use things already started up because the binaries are gone, but the configuration files in /home are still there (although /usr/bin remains)
Ideally, there would be a big UNDO button somewhere in this long row of function keys. Reasonably, there should be some kind of restoration tool. Realistically, I think I'm going to have to reinstall the system, which wasn't easy in the first place due to my faulty disc bay which detects discs at will.
