Re: find 100 first prime number

Oct 11th, 2007

THis is program in java for First 100 Prime Number as "count<100" .
public class PrimeNumber
{

public static void main(String args[])
{
int num=4;
int count=0;
System.out.println("First 100 Prime Number is: ");
System.out.println("1");
System.out.println("2");
System.out.println("3");
while(count<100)
{
num++;
if(num%2!=0)
{
int dv=3;
while((num%dv!=0)&&(dv<=((num-1)/2)))
{
dv++;
}
if(num%dv!=0)
{
count++;
System.out.println(num);
}
}
}

}
}

actually, it prints the first 102 prime numbers (if it works at all)...

As people are clearly allowed to attack me but I'm not allowed to defend myself, I no longer post to this site.

1 is not technically a prime number either so it is not true to print it out as prime with two and three.
