I need to create a program that tests whether or not a number is prime. It needs to use dialog boxes instead of running the program in DOS.

Plz write this for me. The whole program.

really? Why the hell would I wanna code your entire program? Including the gui which would just be annoying to code. But since im nice I'll give you a hint on the prime number algorithm. Use a for loop and test if x(inputed number) mod y(incrementing number above 1 and below x) = 0. If it does break the loop, the number is prime. Now do your own homework.

I was being sarcastic, and you dont need to code the gui, you just need to use the regular windows dialog boxes like so

input_string = JOptionPane.showInputDialog ("Input an integer number.");

You could have google'd this.... but here is a simple implementation

(sorry its not line spaced)

public static boolean isPrime(long n) { boolean prime = true; for (long i = 3; i <= Math.sqrt(n); i += 2) if (n % i == 0) { prime = false; break; } if (( n%2 !=0 && prime && n > 2) || n == 2) { return true; } else { return false; } }

and as for gui... don't do it by hand get netbeans or something to build the gui for you... will save you a ton of time and it wont be messed up. Accessing the components like text boxes and buttons shouldn't be to hard for a beginner.

better yet, just do it in assembly and use a binary search in a look up table... prolly only take you a few thousand CPU cycles for a 32 bit unsigned int and then... well that would take like half a millisecond.
