I am in my second Java class now(I'm a noob!) but our book and professors for the courses at my school use the first method that you have shown. So, that may explain some students doing that method. I like the second method better though.

I just started recently working with java and excel files(still learning), but I have not incorporated mySQL in it. But here are a couple basic sites for getting started with java and excel that I have found useful: [URL="http://www.vogella.de/articles/JavaExcel/article.html#createexcel"]http://www.vogella.de/articles/JavaExcel/article.html#createexcel[/URL] [URL="http://www.andykhan.com/jexcelapi/tutorial.html"]http://www.andykhan.com/jexcelapi/tutorial.html[/URL] Hope these help, I found them great for learning how …

If I am understanding your question correctly you just want the output to be the length of the string that the user enters? If so you do not need an array. Some of the problems I see is in line 14 you have declared an array of strings and then …

Declare database too: [CODE]String db = "yourdatabase";[/CODE] and add database like seen here: [CODE]conn = DriverManager.getConnection (url + db, userName, password);[/CODE] Also, add port number and [CODE]e.printStackTrace()[/CODE] as mentioned above.

Hi All, If I read in from a file and populate an array with its data(all strings), how can I control the way it prints(to the console for example).Right now it just prints a huge long line in the console of all its contents. I figure I will have to …

[QUOTE=lbgladson;1695362]I changed it to ActionListener but now I'm getting an error for ColorListener. What do I need to change that to?[/QUOTE] I think because your method in the ColorListener class is stateChanged(), make it actionPerformed().You can write this code with a lot less if you want.

I've never seen video do it, but facebook and iPhoto have facial recognition for photos, so I would think in theory if a video could be slowed to a very low fps then maybe a comparison could be done? Ok I googled it real quick, looks like they can do …

Can you show the error please. Or post me your whole code, so I can check it out in my compiler.

In line 3 you have if(if "condition". Don't think there should be two ifs there. You should not be testing a button group either. It is just something that can group radio buttons, checkboxes, etc... together. Test the individual checkbox/radiobutton(whatever you have) instead of the button group. Try something like: …

This is the same code you posted before, with the same problems. You are not assigning a value to grade after initializing it, as already stated. Also, with what you have you are only going to be able to have a maximum of one grade entered.

Ok I put your code in my compiler to see what it was doing. First off they way you have it written the user can only input 1 grade anyway, so no matter what score is entered it will only add one. So your output would only be something like: …

Post your code so we can see where you are stuck at.

Hi all, I have a main GUI class as seen here: [CODE] import java.awt.*; import javax.swing.*; import javax.swing.border.*; /* * Class is to communicate with various other classes in the program to * create a roster for user based on their selection on GUI. */ public class MainGUI extends JFrame …

I did not see anything in the math class here, but you may want to double check: [url]http://download.oracle.com/javase/6/docs/api/java/lang/Math.html[/url] But if I'm correct f(x) = y is very vague and just means x=y because you are not actually giving us a function to apply to x. For example: We will use …

Hi all, If I write a java program inside of eclipse, how can I run that program outside of it, rather than just hitting the run button in eclipse. So, I can give others the program to run on their computers. Thanks!

Hi All, I am currently trying to figure out to finish this project. Below is my code that I have so far. There are some blank methods that I am not sure where to even begin on how to complete them. I have a description of what the methods should …

Hi All, The GUI works as intended to. But I was wondering if some of you java gurus could look over my code and maybe give me some tips on how I could have written this code better. Thanks!
