Hi saher_omer,

In future, please start a new thread if your question is not directly related to the original poster's problems.

But to answer your question, there are many examples on the net...

The main method in a java application has the following signature:

public static void main(String[] args)

If you are a beginner I would suggest starting with something a bit simpler than a...

You type java Hi, there is no need to specify the ".class" to run your program. Also, you will need a main method in that class to run the program.

In PHP the strtotime (http://au2.php.net/manual/en/function.strtotime.php) and date (http://au2.php.net/manual/en/function.date.php) functions might be useful to you. You can go:

for($i=0; $i<10;...

Hi alreem,

We can only help you if you show that you have made some sort of an attempt. Do you have an algorithm or some code that you have tried? We may be able to point you in the right...

Try adding the following line to your script, anywhere after the line $dir = $documentroot . '/' . $username; but not inside the function:

Hi erlene and welcome to DaniWeb :)

You don't need to use Math.pow at all. Math.pow is used to find the power of a number. I wish that banks would pay interest exponentially but unfortunately... ;)...

Not sure what DaniWeb's policy is, but for other forum-type sites that I have contributed to we kept all PM's, emails, forum posts in database tables. If the owner of the message deleted it (by...

String number = Float.toString(number);

I think what you are trying to do is convert the number n to a string yes?

What I would do is this:

String number = new Float(n).toString();

Hi ankiwalia and welcome to Daniweb :)

Your SQL syntax is incorrect. Instead of this:

String query="select username and password from Registeredusers";

Try this:

So is $title the title of a single RSS feed item? If so, you can do something like:

$count = 0;
foreach($rssFeedItems as $title)

There are a few different types of SQL, but http://www.w3schools.com/sql/default.asp is a good site for general SQL knowledge. http://www.sql.org/sql-database/sql-tutorial/ is a good beginner's...

When you say you suck at math, how bad is it? Are we taliking about not knowing advanced calculus and algebra, or not knowing your times tables? Who are you comparing yourself to?

imagedestroy() is used to free memory assigned to an image resource stream. I haven't tried it out, but I assume it can be used to free any image resource stream created by the GD package.

I assume you want $nowdate to be a string. String concatenation in PHP uses a period character to join strings. This **should** work:


$nowdate = date('Y') . "-" . (date('Y') + 1);

In order to tell what parameters you need to pass to the method, you can look at the method signature. In your Pizza class, let's look at how the setSize method is described:

I think in this situation you are better off explicitly joining the tables by account id. Like so:

SELECT COUNT(J.account) from JanTable J
INNER JOIN FebTable F
ON J.account = F.account
WHERE...

Hi vimotaro,

Are you asking if you receive a record you want to update an existing one with the data in that received record? If so, you can do this quite easily by running a SELECT COUNT(*)...

Yes, except that you don't have to define the code for Reptile::eat() because it is in the Animal class. If you wanted to change the way that the Reptile eats from the way that the Animal eats then...

Should zipCode belong to the Individual class or the IndividualArray class? I think it is a value relating to the Individual, not the list of Individuals.

First, make sure that the SQL file has statements that read like this:

CREATE TABLE IF NOT EXISTS Example
-- table definition goes here

Then you actually need to run the mysql query by typing...

I think it may possibly be out of beta now - that post is almost 2 years old... :P

Your DB structure looks ok, except that I would probably just sort by name and remove the sort_name field. Your SQL query will look something like:

SELECT * FROM table_ads
INNER JOIN...

www.php.net is probably a good place to start. This site has some really good documentation and sample code. Of course, if you get stuck there is also DaniWeb :)

You need to call Graphics2D.setStroke(Stroke) method before drawing a line. You will need to create a Stroke first - use the BasicStroke class for now. Also, don't forget to reset the stroke after...

Your problem is in the first if-statement:

You are using an assignment here rather than the comparator == as I think you mean. In PHP though, your...

Rather than implementing the ActionListener in your class, it is probably better to add an ActionListener to your menu item. You can do this by

dReg1 in the above code is an Accumulator, a register that is used to keep track of the result of the calculations. If you think about how a calculator works, you enter a number, press the operator,...

Hi and wecome fellow Aussie! (We are slowly taking over Daniweb) <insert evil laughter> :D

It looks to me like it is a flag to tell whether something has been inputted or not. If it hasn't, isFixReg is set to true, and pressing a number (for example) starts a new String. Otherwise,...

Ok I don't want to give it away, but the line String "type"; is not how you initialise a String. And it is in the wrong method.

You have moved the line Triangle T = new Triangle(); from where it...

I like the solved threads count. But maybe as a compromise the moderators/administrators of daniweb could have this info removed from their profiles? After all, they are moderators so we all know how...

Hi piers,

The problem is that you posted a huge chunk of code that any of your fellow students could copy easily by searching for "scanner" in google. I think that is what the person is implying...

Hi Libran,

To help debug your code, try adding some println statements to gain a better understanding of what is going on. Please see my comments below.
