public class SumOfPrimeNumbers1

{

public static void main(String args[])

{

int count, sum = 0;

for(int number = 1; number <= 200; number++)

{

count = 0;

for (int i = 2; i <= number/2; i++)

{

if(number % i == 0)

{

count++;

break;

}

if(count == 0 && number != 1 )

{

sum = sum + number;

}

System.out.println("The Sum of Prime Numbers from 1 to 200 is: " + sum);

}
