The database problem should be dealt with by the Web Server solution you choose. Which brings me to the next question.

Why Java? (How) do you intend to get Java code working? Confused | :confused:

That option should also be part of your Web Server solution.
Specifically Java Server Pages, and I think you should look at learning web *server side* features first. So that you aren't trying to solve problems which are already provided for you in a server solution.

What type of options did you get with your website?

Smile | :)

Here's the Java & Javascript, both identical, for you to compare.

Ignore the fact that there is no random number generated yet. I just want to get arrays with difference between IsToken and all numbers NOT in that array. I have split it back into 3 x 6 so that it will be easier to manage if you then store them in a database.

This is output from the Java version:

Ok thanks this is right java dublicates method.. I have already compiled your code as .jar

http://maverick.8m.net/myApps/Dusty_dex_randomnumber.jar[^]

but an corrupted jar is that file for giving error should have some library or file existing in IDE. Well do you compile jar file valid as phone?

needs to any definition or adding library to compile it as phone or tablet? Thanks a lot for help and coding.

I think you messed up the jar by renaming it Dusty_dex_, just name it RandomNumber.java (it should be same name as the Class in the file).

OK, this code is using System.out.println but if you want to see output via graphical UI (java.swing)
then you will have to \\comment out the System.out.println bits. And learn more about developing for phone.

It has never been an area I was bothered about, so I can't help you with phone development.

You can post the original errors and I'll see what could be missing. (besides developer knowledge)

Let me know if the javascript is any use. I could still work with that code, and convert it without a problem.

dusty_dex13-May-13 3:24

13-May-13 3:24

NO. I mean yes, I know the javascript works. All of it works. You can test java without using phone tools.

But is the code doing what you want it to? compared to your own code that you posted. (which is a mess)

The java code needs modification in order to work with a GUI and not command line interface (CLI), which I use for compile & run.

Can we concentrate on JAVASCRIPT first. Worry about Java later. Wink | ;)

Have you used the very first version?

I posted it again, and that version does work. It should look like this

It was this and a few minor {} [] differences I overlooked. I had converted Java code back to javascript and posted it without checking. Sorry.

The function is expected to return int

Java

public static int Random(int nu)

Any boolean test (== != > >= < <=) will give true/false answer, not the int.

That is your mismatch.

Java

public static int Random(int nu)
	{
                int see;
	    final int MAX_DATA = 49;
		nu = (int) Math.round(MAX_DATA * Math.random()+1);
		for(int j=0; j<MAX_DATA; j++)
		{
		    int[] arr = new int[MAX_DATA];
		    see = (int) (MAX_DATA != arr[j]);
                    // Hakan: This will not compile either

Hi,

I want to hide specifically two columns in a table using JQuery. I have the following code to do it:

$(".classname").hide();

But the thing is the same class name is used in all other columns in that table. So all the columns are getting hidden when I execute this JQuery.

Is there any other way to hide only those two columns? Frown | :(

Please Help.!!

Thanks in advance
Ashwini

One way to do it is create another name on your CSS for the columns you want to hide, such as the one below

CSS

.classname, .hidecolumns{
/* Your CSS here */
}

Use the .hidecolumns class on the tags you want to hide, instead of using .classname. This way, the existing tags using that class would not be affected.

JavaScript

$(".hidecolumns").hide();

Signature construction in progress. Sorry for the inconvenience.
