hello this is Saad
there is a Question revolving in my Mind that why a Set is UnOrdered
? ?
|
|
|
|
|
by definition.
sometimes an order is irrelevant to a collection, then use a set. It is like a mathematical set (remember Venn diagrams?).
without any order, adding and removing items can be very fast operations.
|
|
|
|
|
as Luc says, it's so by definition.
the Interface Set[^] is an extension to the interface Collection. And a Collection is unsorted - so it's most likely an inherited behavior.
|
|
|
|
|
As a guess, most collections do not need to be ordered.
Thus ordering is something that is best done by adding it to a collection when needed.
Also if collections started out ordered then attempting to make them unordered, for performance reasons, would probably be hard if possible at all.
So better if everything started out unordered.

|
|
It is because, there is a SortedSet in java.

I have created a Java game (183MB for .jar file) and can be played on local (offline) through .html and it works perfectly fine. However, once it is allocated into the server in my University, it does not run as expected and it projects the following exception:
load: class wildwildwest.applet_selection_screen not found.
java.lang.ClassNotFoundException: wildwildwest.applet_selection_screen
at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source)
at sun.plugin2.applet.Plugin2ClassLoader.loadClass0(Unknown Source)
at sun.plugin2.applet.Plugin2ClassLoader.loadClass(Unknown Source)

at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)
Exception: java.lang.ClassNotFoundException: wildwildwest.applet_selection_screen
What causes the above problem and what solution can be proposed to solve it?
By the way, the .html code for the game is as followed is as following:
<HTML>
<HEAD>
<TITLE>Wild Wild West</TITLE>
</HEAD>
<BODY bgcolor="#000000">
<font color="#ffffff" face="Curlz MT">
<center>
<H3><HR WIDTH="100%">Wild Wild West<HR WIDTH="100%"></H3>
<P>
<APPLET CODE="wildwildwest.applet_selection_screen" archive="Wild Wild West.jar" width=800 height=600></APPLET>
</P>
</center>
</font>
</BODY>
</HTML>

Check this link[^], it has most of the common problems for deploying an applet.

Thanks for the suggestion but it doesn't seems to be able to solve the problem. There are others java games has been uploaded onto the same server but only the one I have is not able to work online while the rest can be loaded and played.

If there are other applets running without a problem, I'd suggest you investigate the differences.

check the libraries you're using. Might be a indirect reference, which causes the deployment not to find the jar and therefor not to work proper.
Also check your build-Config, sometimes not all classes are marked to be added to the build.
|
|
|
|
|
Thanks for the information. I will try it out as soon as possible.

Huh?
Jars don't have dependencies - classes do.
If the specified class is in the specified jar and the class has another class dependency which is not found then a different exception would be the result.
Perhaps you meant something different?
|
|
|
|
|
Maybe try changing your jar filename to no spaces.

thanks for the suggestion. I will try to solve it.

The class is not in the class path. The solution follows from that.

Which means it is in the class path.
Although it isn't clear what you mean by "through .html".
I will note some oddities.
1. 183 meg is a really big jar
2. Class name doesn't follow standard naming.
3. Jar name shouldn't have spaces in it.
What happens if you change, ONLY in the html, to XXX.jar? That should specifically fail because the jar doesn't exist. However if you get the same error then I would suppose that your jar is not being found on the server (thus it won't be in your client and not in the class path.) That is a guess though.

Hello,
public class Doc extends PlainDocument {
private static final long serialVersionUID = 1L;
protected Element createBranchElement(Element parent,AttributeSet a)
{
return super.createBranchElement(parent, a);
}
}
public class TestDocView {
Doc D = new Doc();
AbstractDocument.BranchElement E1 = (BranchElement) D.getDefaultRootElement();
D.createBranchElement(E1, A);
}
I get runtime error for
D.createBranchElement(E1, A);
saying Illegal casting of AbstractDocument.BranchElement.
How should I use CreateBranchElement()?
Thanks
Prithaa

|
|
|
a runtime Error??
Please use an IDE. Eclipse and Netbeans are free. No need to work on console.
Your Exception pops because the method createBranchElement(Element parent, AttributeSet a) is inheriated from AbstractDocument[^]. I guess it doesn't return much.

You haven't shown us the implementation of
getDefaultRootElement()
Also, what's the relation between BranchElement and Element.

Hi Friends,
I would like to know , how to write a timer program.For eg the application should trigger after a particular time.Thanks in Advance

Trigger what? Do you mean that it should run doing nothing until a certain time of day or until a certain time interval has elapsed? In either case a quick look at the Java documentation for something to do with Date[^]s or times should help.

Don't believe Richard, for him time is something that is flying by  
GregorianCalendar [^]is so much better!
Combine it with This one about running System Commands[^].
The rest is up to you - that is what development is about. Make a plan, write things down, sketch a GUI and afterwards start implementing what you've written down.
