it looks like it is complaining because the getSource is getting a javax.swing.JMenuItem, yet you are trying to use it as a JButton instead.

the code you currently have is trying to construct a test object, but test is simply a method you call. therefore, you can simply say x = test();, furthermore when you are printing the result, is it...

if you think this is so, you should code yourself, because these tools need to accomodate many variations and so the code become "horrible".

I am worried when you say "their files", and "all over the world". If you are talking about files/database on some server then I would agree, but if you are talking about files on a client computer,...

if you are using == you are going to need to trim the decimal places down regardless. just make sure you do comparisons in an order that ensure you get what you want.

you have already answered your question yourself. you are using a "counter" and so using this you can emulate the sequence.

that is recalculating "pi" not "piequals". look at the mathematical sequence, you should see what is happening...

ok, i am not entirely sure what approach you taking for this problem, but it seems a bit iffy so far. do you actually want an infinite loop? (i would have though not...)

anyway, the maths needs to...

you have infinite loop because you are checking for plusminus == 0 or 1. when the value is 0, you add 1, when the value is 1 you subtract 1, therefore the condition is always satisfied.

did you even read my question?

if you "break" you are going to skip the calculations. does the calculation need to be in the loop?

you need to somehow "remember" values from previous iterations of the while loop. so if you have a MAX number of iterations you could use an array, but perhaps it would be easiest to use a vector...

ah yes, forgot about that, definitely needs to be considered...

if you write the code, it belongs to you. you can choose licensing on what you have written.

what are your inputs?

you do realise you have 2 while loops to satisfy?

sure by declaring it as a String won't "start it out as an int".

i am pretty sure you got that backwards there stephen.

"For example I would enter 12345 and 1 2 3 4 5 would be returned."

http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html

in C, classes will teach you to treat a String is simply an array of chars, and i think you should keep this in mind here.

i am not sure what your requirements are, but the easiest way to...

i assume you are going to keep your input saved as a string. if so, is it always a space between each element (char)? or will there be instances where it may be "12 3"?

read the api on String.split(). it doesn't do what you think it is doing.

firstNumber and secondNumber are Strings (I am pretty sure you know this). since they are strings, == will only evaluate true if they are the same object. you want to use .equals to compare Strings...

out of curiosity, what is generally your "fix" to this issue? (it may provide some clues)

ah, damn, guess i am wrong (you put that code within your ButtonListener right?).

well from the behaviour you have explained, (String)bankaccount.get(0) must be evaluating to an empty String.

ok, so if you did something like text1.setText("random text"), does this produce anything into the TextArea?

my guess is not, and so, as I said you have different instances of your objects.

what sort of errors do you get, or nothing happens at all?

i have a feeling that your ButtonListener is not using the objects created in Away (the ones you want it to, anyway).

what is the point in returning "enter" when all your logic related to "enter" is already complete within the method? and as i said previously, simply returning a value is useless unless you actually...

you are returning the value, but doing nothing with it. another question, are you actually returning the correct value?
