What do you mean? Yes the iPod is worth $250 and I am paying $5 for each person who signs up. However, if you wanted the iPod, you would have to sign up on the site anyways (and then do the same thing I am). So it's a win-win deal...because even if you don't want to sign up, it takes all of 5 minutes to do. A buck a minute...that's not bad by my standards.

freeiPods.com is giving away free iPods. This is not a scam. (See http://portableaudio.engadget.com/entry/1771223899144212/ for proof of its legitimacy.)

In any case, I need 5 people to sign up using the below referral link and then sign up for one of the offers on the site. All of these offers require a credit card; they are the type of deals where you sign up and then you just have to remember to cancel the free trial before the end of the expiration period - that is the only annoyance.

Personally, I would suggest signing up for the AOL offer because it is the most reputable and known for good customer service, so cancelling won't be a hassle. Additionally, I am personally intrigued by their music service. But sign up for whatever you want using my referral link and I will send you $5 in Paypal (or any other method). It should take only about 10 minutes. One suggestion - when you sign up, make sure you uncheck the boxes that have something to the effect "Sign up for promotions by our sponsors" - that is, unless you enjoy spam!

Any questions? Send me a PM or email me at dav8571@hotmail.com

Ok, scratch that one too. That one finds an incorrect prime, due to the uncertainty of approximations that end in "9." Re-thinking...

Haha I skipped some didn't I! Sorry that's what I meant

1, 2, 3, 5, 13, 31, 74....ad infinitum

Wait I take it back - that isn't quite right. Doubles are not going to cut it - must adjust with BigDecimal.

public class Google{ private static int decimalplaces = 0; private static int magnifyCount = 0; public static void main(String[] args){ double e = 1; //Set e to 1 in order to avoid calculation of 0! boolean primeFound = false; //Until prime is found... long denom = 1; //Initialize to one to avoid x * 0 = 0 in factorial int count; //Used to create factorial for(count = 1; count <= 15; count++){ //get at least 10 decimal places of expansion denom *= count; e += 1.0/denom; } double eMagnified = magnify(e); System.out.println(eMagnified); while(!primeFound){ if(isPrime((long)eMagnified)){ System.out.println("----------->" + (long)eMagnified); primeFound = true; } else{ eMagnified = truncateLeading(eMagnified); System.out.println(eMagnified); if(decAcc(denom) <= magnifyCount-1){ //If there needs to be another term added... denom *= count; //Essentially, this is the factorial in the eMagnified += (1.0/denom) * Math.pow(10, magnifyCount); //denominator of the Taylor expansion - //increase once every iteration System.out.println("+" + 1.0/denom + "=" + eMagnified); try{Thread.currentThread().sleep(500);}catch(InterruptedException ex){} count++; } } } } /* Recursively finds the number of accurate decimal * places represented in an approximation to a series * of X(n), where x(n+1) < x(n). The series must be * convergent. * * @param The reciprocal of a fraction of * the form << 1/x >>, (i.e., x). * @return The number of accurate decimal places represented * by the reciprocal of the nth term. */ private static int decAcc(long reciprocal){ if(reciprocal < 10){ int temp = decimalplaces; decimalplaces = 0; //Re-initialize for subsequent calls return temp; } else{ decimalplaces++; reciprocal /= 10; return decAcc(reciprocal); } } private static double truncateLeading(double eMagnified){ long base = 1000000000; for(int i = 9; i > 0; i--){ if(eMagnified >= i * base){ eMagnified -= i * base; //remove the leading value eMagnified *= 10; //shift left by 1 magnifyCount++; break; } } return eMagnified; } /* Gets the leading ten numbers of the * e expansion and converts them to an * integer. */ private static double magnify(double e){ double upperBound = 1000000000.; if(e >= upperBound){ magnifyCount = 0; return e; } else{ e *= 10; magnifyCount++; return magnify(e); } } private static boolean isPrime(long testLong){ for(long i = 2; i <= (long)Math.sqrt(testLong); i++){ if(testLong%i == 0) return false; } return true; } }

Do you want something like this?

myBoolean = true; while(!myBoolean){ //this is satisfied until i explicitly say so. if(!r.getStatus()){ //this is NOT satisfied until the user submits. myLabel.setText(r.getUserName()); myFrame.hide(); } else myBoolean = false; }

There is fundamentally no difference if you un-comment //throw new SimpleException(); All you do is force it through the if statement, upon which it will throw the same exact exception.

I just compiled your code fine. If you are having problems, check the file name - be sure that it is saved under SimpleExceptionDemo.java, which is the main class.

Here is the part of your code that I'm having trouble with:

public static void main(String[] args) { SimpleExceptionDemo sed = new SimpleExceptionDemo(); try { System.err.println("Caught it-1!"); sed.f(); System.err.println("Caught it-2!"); throw new SimpleException (); } catch(SimpleException e) { System.err.println("Caught it-main()!"); } System.out.println( "main()"); }

The first statement in your try block will always execute; I'm not sure what you're trying to accomplish by putting that there. The second System.err.println statement will never execute because f will always throw an exception...Your catch block is always catching the exception throw by f(), not the SimpleException thrown at the end of the try block. Hope this clears things up.

In reply to your first question: when a method, either explicity -- as yours does -- or potentially, throws an exception, it must be declared as thrown. Otherwise you face a runtime exception if is thrown and the method is not expecting it.

Why don't you try putting them in the same folder...see what happens, do a little experimenting...

Do you have any MouseListener interfaces implemented in your cells?

Your best bet would be a JTextArea (http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/JTextArea.html), which you can set scrollable in either vertical or horizontal and (non)-editable.

Oh, I just re-read your post, and all you need is lines connecting the points! Ignore the above post in that case!

What I would do is use Graphics's drawLine method, implemented in a for loop.

For example:
public class MyClass { private int xCoords[] = {3,4,6,89,9,.....}; private int yCoords[] = {5,6,68,56,54,.....}; //....other code public void paintComponent(Graphics g) { super.paintComponent(g); g.setColor(new Color(54,34,56)); for(int i = 1; i < xCoords.length; i++) { g.drawLine(xCoords[i-1], yCoords[i-1], xCoords[i], yCoords[i]); } } }
