Hey everyone,
i'm was wandering how i could implement a 'Serializable Hashtable'?
since i'm working on a program that needs to read some information (student profile such as name, student ID, contact detail etc) from a text file, in the form of hash table, and show, edit or even delete the info from that file.
I'd appriciate any sort of help.
thanks

java.util.HashMap implements Serializable.
So as long as the data items in there also do that then it works.
Note that a serialized object should not be considered 'text'. If you want something like a cvs file then you should probably just focus on that.

Hi,
I am trying to find a good reference on how to create a pop up social bookmarks menu. This site has exactly what I want. You can see it by clicking on any article and hovering over the 'Share' link at the top. A window pops up with links to facebook, diggit....etc. Does anyone know of a good example on how to do this and how to send the information to each of these sites?
Thanks!
Lisa

I'm using JDK5 (1.5.0_14) for compiling my programs, but my customers runs JDK6 (1.6.0_06) on that pc (say vista). Someone said my programs recompiled with JDK6 because target environgment is JDK6.
I doubt it, but weakend.
Can anybody explain these?
And I must say, I'm using jni dll targeting jni1.4 with above codes, that has some trouble; sometimes vm crashes in gc.

I want to know in what direction have i to go to program a look and feel?

This is a rather vague question. Do you mean a UI layout? Code layout? Function flow?

This is fully documented by Sun and there are a number of books that cover it. Try typing "java look and feel" into Google. It's a fairly big subject so don't expect too much of a detailed answer here. The easiest option might be to look at the Synth look and feel which takes away a lot of the hard work involved in coding a new L&F.

I am from C# background. I would suggest use ArrayList and then it may have a sort() function to either do the ascending/descending.

Hi,
you could start with some collection (a Vector, an array, ...) initialized with all the symbols in sorted order; then remove each symbol one enters; when done, list what remains.

Have a look at the <code>java.util.SortedSet<E></code> class for unique items.
Or add the elements to an <code>java.util.ArrayList<E></code> and then pass that through <code>java.util.Collections.sort()</code>.

i'm using java awt in front end and microsoft visual foxpro 6.0 as the back end
the project is completely working but the problem is that anyone can click on the table and can edit the table contents what shall i do to stop the modification in the database??

Where are the 'backend' foxpro files? If they are on a physical server can you not restrict access?
The is a similiar problem to MsAccess, if the user can access the file and has the correct program installed then they can change the content.
A long term solution would be to migrate to a more secure data storage engine.

If you mean the files themselves then that isn't a java question. It is a database/security question.

i want to write a project in j2me. its an app that could be used to connect to a database and download txt, videos and animations with presentations. also it has to have a media player for these media. please any assistance would be deeply appreciated.

What is your target device? With J2ME, there needs to be a target configuration. Conected device [CDC] is the common one for PDA/Smart Phones.
I would start by trying to create a simple HelloWorld and getting it to run. If you want to have downloads, etc, there are a lot of security issues and permissionings that need to be covered as well.
Now, what research have you done so far?

You should try google and then maybe ask questions here.
It appears to be something to do with apache[^], so I guess you'd use it when building intarweb thangs.

Simple piece of history. Chris told us off on Friday for flaming without thinking about the person asking the question. I have taken a few minutes to carefully consider your posting.
This is not a question. You have come in and asked for code without trying anything. The only thing worse would have been to add URGENT!!!!
You will get no help here.
