prime numbers[Resolved by manavo11]

I was trying to create a program that printed all the prime numbers within a given limit. My program is printing out all of the numbers! See if you can figure out where I'm going wrong:

Code:

---

import java.io.*;

class PrimeCheck
{
        public static void main(String[] args) throws Exception
        {
                BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
                System.out.print("Limit --> ");
                int limit = Integer.parseInt(br.readLine());
                System.out.println("");
                System.out.print("Primes --> ");
                int count = 0;
               
                for (int i=2; i<=limit; i++)
                {
                        for (int j=1; j<=i; j++)
                        {
                               
                                if (j * i == i)
                                {
                                        count++;
                                }
                                if (i * j == i)
                                {
                                        count++;
                                }
                                if (count == 2)
                                {
                                        System.out.print(i + " ");
                                }
                                count = 0;
                        }
                }
        }
}

Code:

---

import java.io.*;

class PrimeCheck
{
        public static void main(String[] args) throws Exception
        {
                BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
                System.out.print("Limit --> ");
                int limit = Integer.parseInt(br.readLine());
                System.out.println("");
                System.out.println("Primes --> ");

                boolean bIsPrime;

                for (int i=2; i<=limit; i++)
                {
                        bIsPrime=true;
                        for (int j=2; j<i; j++)
                        {
                                if (i%j==0)        {
                                        bIsPrime=false;
                                }
                        }
                        if (bIsPrime==true) {
                                System.out.println(i);
                        }
                }
        }
}

I'm sure it can be optimized but it works :)

Thank you. This is the way I wanted it, because I already had a one line approach that looked something like this:

if ((i < 8 && i % 2 != 0) || (i > 9 && i % 2 != 0 && i % 3 != 0 && i % 5 != 0))


but of course I didn't like that!

So thank you for helping me.

You're welcome :) How about "Resolving" the thread? ;)

No I did it before you.

You added [Resolved] Then I added the green check mark. Then I changed the name to Manavo. Was it you that changed it back to manova? Well I have changed it back to Manavo now at least...:)

You're killing me. manova12? :cry: I'll change it myself :afrog:
