Start with using valid math symbols so that your program will compile.

Yes, a List of BufferedImages may be a useful way to go, especially if you wish to merge layers later or flatten to a single image.

Personally, I have no interest in playing with some tutorial to see if I can recreate "nothing happens". Perhaps someone else does. I can cause nothing to happen by just sitting here at my desk; it doesn't really help resolve your issue though.

Post your code and describe what isn't happening.

Your original code had no variable named 'years'. Post your updated code.

Note that you have defined more private variables than your instructor requested. He/she may only want you to include the ones called for.

Your class already contains the variables (yes, the private ones up top) needed to make the calculation, so you can use them directly and return the value.

A side note, check your constructor carefully and note that you're using the exact same names for the parameters and instance variables you're setting. It might have some consequences in your program if you don't properly qualify them. Check your class notes on that.

So he asked for

//this method calculates and returns the Future Value.
double futureValue()

How does that compare to the method that you wrote?

Then he must have explicitly told you which methods to implement in your class. His tester class obviously works against a very specific interface and something about your own class is not matching up.

Check the method call parameters in the class he gave you versus the futureValue() method that you have defined. Do the parameter types match?

Have you checked the "Getting Started" thread over in the JSP forum? http://www.daniweb.com/web-development/jsp/threads/249070

Double posted. Please refer discussion to the other thread in JavaScript: http://www.daniweb.com/web-development/javascript-dhtml-ajax/threads/384154/1654451#post1654451

Closing this one.

You'll need to open your output stream in append mode:

"nothing happens" is a bit thin to go on. What jars and what code?

Many of the software development forums have a sticky thread featured at the top for recommended resources on getting started with or improving one's knowledge of that language. VB.NET currently has no such resource listing.

I personally do not work with VB.NET, but if those who do would like to post recommended resources here in this thread I can compile such a sticky thread for the forum. It can be very helpful for both the newbies seeking resources and veterans who are tired of making the same recommendations for the seventy-fourth time. ;)

The thread itself will most likely be a work in progress that I will edit as necessary to keep it cleaned up and on-topic.

Sounds like your teacher wants you to learn it, so learn it.

Also, drop the "chat speak" and write in actual English. It's against the forum rules.

The answer seems very clear: You should write the project in VB.NET.

I would assume that you would use your "studentmarks" class in your main method, but that's entirely up to you. I assume you have some assignment.

I just told you why it was not running.

You have to write it. A class needs a main() method if it's to be invoked externally

public static void main(String[] args){
...
}

You have no main() method defined. You cannot run a class that does not contain a main method.

No, I doubt he can because he simply copied and pasted it here from another post he saw elsewhere - which is why I have deleted it.

@glamorhits: This is a direct copy of code that you found here: http://wiki.answers.com/Q/Inverse_of_matrix_in_java

It doesn't seem that you have put any effort of your own into this and simply want others to finish it for you.

... and what is your specific question?

You're welcome to ask for help with specific questions in this section of the forums, but asking people to write code for you belongs in Web Development job offers.

We do expect people to demonstrate an effort on their own. It's not a code-by-request service.

So this is a job offer?

Threads merged. Please don't start additional threads for a single question.

Moving to JS.

Okay, so what is your question?

Shower, coffee, drive - just another day of work.

You should not override the method isCellEditable on DefaultTableModel
but override it on the JTable itself

And what is your reasoning for that?

Please note this was posted nine months ago.

Consider that your series of "if" statements to evaluate the grade is outside of the loop where "Grade" is being entered.

Also be aware that you should use .equals() or .equalsIgnoreCase() to test string equivalence. Do not use == .

Take a glance at this article from the OpenGL wiki about drawing 2D controls over a 3D scene: http://www.opengl.org/wiki/Viewing_and_Transformations#How_do_I_draw_2D_controls_over_my_3D_rendering.3F

@Curt1337: No, no one here will convert the chat server that you copied directly from Rose India to UDP so you can turn it in as a work product.

As Norm said, hire a programmer if you want someone to do your work for you.

You really should not stuff all that GUI code into your main() method, but that's another discussion altogether.

You can still get a reference to the class statically and use getResource like this

Main.class.getResource(...)

Perhaps he means something more descriptive and meaningful than 'j'. If 'j' were being used as a line counter for example, using 'lineCount' would be easier to follow than 'j', which itself has no intuitive meaning.

And J2EE if you're interested in the web/enterprise branch of Java.

I never bothered with it myself. Perhaps it may help you get that first real job, but beyond that your working experience will be more of a factor than certs in future work. I only know one person who bothered with the JCP and that was only because he was between contracts at the time and just looking for something to do.

If you do decide you'd like to take it, don't pay some prep company a bunch of money to train you for it. There are plenty of reference and practice exams available on the net.

> And is OCPJP alone any worth?
It shows you can study for and pass basic tests. That is about all.

You haven't specified what you are having trouble with. What is it doing or not doing currently? Where do you believe the problem lies?

You can't expect people to just fix the code for you. You need to ask specific questions and make the effort to work through them.

... and your question is?

> Without how things differ it is difficult to advise on any sort of design.

Exactly. So it's odd that you declare anything "lazy". There aren't enough specifics to answer in detail and the OP never bothered to discuss it any further beyond the initial post.

It should work fine then. It runs without any errors on my machine on 1.6. The error message reads as though you're running a version older than 1.5.

What Java version are you running this on?

Post exact error messages. Don't expect others to search and guess.

Yes, you can write your own Comparator to compare on the field you are wanting to search by and supply that as a parameter to the binarySearch() method.

You can find a straightforward example of that here.

Please clarify exactly what you are having trouble with.

You have to compare two different arrays of characters, which would require two loops, yes?

I only see a single loop in your function.

It should also tell the line the error is occurring on.

It also tells you which method invocation it's choking on. Read it closely.

Perhaps you could elaborate on "a few failures" rather than expecting people to guess?

Start by making a JPanel within a JFrame with a text box to enter a name, a button to submit it, and a list to display them.
