I NEED TO Write a program that meets the following requirements: Declare a method to determine whether an integer is a prime number. Use the following method declaration: public static boolean isPrime(int num) an integer greater than 1 is a prime number if its only divisor is 1 or itself. For example, isPrime(11) returns true, and isPrime(9) returns false. Use the isPrime method to find the first five hundred prime numbers and display every ten prime numbers in a row, as follows: 2 3 5 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 73 79 83 89 97.....etc > I NEED TO Write a program that meets the following requirements: > Declare a method to determine whether an integer is a prime number.

HA! What an a*#hole. Thanks for the laugh. Carl. Carl coughed up: >>> I NEED TO Write a program that meets the following requirements: >>> [quoted text clipped - 22 lines] > > Carl. Except that perhaps the OP isn't someone trying to get away with something. Perhaps he's just someone who needs a place to start. Benjamin, consider this. You can determine if a number is a prime by looping from 2 to the 1 less than the number and seeing if nothing divides evenly into the number. Now, that would work, but would be an unnecessarily long loop. Can you see how to shorten the loop so that it need not go all the way to one less than the number? Once you get something working that determines if a number is prime or not, you can use that to solve your homework assignment. SignatureFramsticks. 3D Artificial Life evolution.

I am not saying it bothers me if people wish to keep talking about it. I am merely pointing out that it is so obvious that the original post comes from someone who has no desire to actually learn java. He is a waste of time and he is wasting his own time taking a course of study which he can't possibly succeed in. >> Please note that the posting came through Google groups, and it has not >> even shown up in the archive yet.

I disagree. The OP does show signs of naivety about how these groups work. But I think it is too early to make determinations as to whether they are willing to put in the effort (and are capable of) learning Java.

I agree with your disagreement. Paul, there are no implicating signs whatsoever of what you are talking about. Signature"I don't want FOP, God dammit!

Now /this/ post is commendable. Most folks in usenet do not admit their errors. To do so indicates a good character. Thank you. Signature"I don't want FOP, God dammit!
