Write a Java Program to find the Sum Of Prime Numbers From Given Range
Input:
Enter the starting number:
5
Enter the end number:
20
Output:
Prime nos from Given Range :
5
7
11
13
17
19
Sum of Prime Numbers From Given Range= 72
Code in Java:
import java.util.Scanner;
public class SumOfPrimrNumbersFronGivenRange
{
public static void main(String[] args)
{
Scanner scan = new java.util.Scanner(System.in);
System.out.println("Enter the starting number: ");
int n1=scan.nextInt();
System.out.println("Enter the end number: ");
int n2=scan.nextInt();
int count,sum=0;
System.out.println("Prime nos from Given Range :");
//condition used to identify number is odd or even
for(int i=n1; i<=n2; i++)
{
count=0;
for(int j=1; j<=i; j++)
{
if(i%j==0)
{
count++;
}
}
if(count==2)
{
System.out.println(i);
sum=sum+i;
}
}
System.out.println("Sum of Prime Numbers From Given Range= "+sum);
}
}
Output:
Enter the starting number:
5
Enter the end number:
20
Prime nos from Given Range :
5
7
11
13
17
19
Sum of Prime Numbers From Given Range= 72
