write a java program to print sum of prime numbers
Answers
To print the sum of all prime numbers up to N we have to iterate through each number up to the given number and check if the number is a prime or not if it is a prime number then simply sum it or add it in one temporary variable.
Answer:
// Java Program to Print Prime Numbers from 1 to N
public class PrintPrimeNumbers1 {
public static void main(String[] args)
{
int i, number, count;
System.out.println(" Prime Numbers from 1 to 100 are : ");
for(number = 1; number <= 100; number++)
{
count = 0;
for (i = 2; i <= number/2; i++)
{
if(number % i == 0)
{
count++;
break;
}
}
if(count == 0 && number != 1 )
{
System.out.print(number + " ");
}
}
}
}
