Hi Friend,

Try the following code:

class PrimeNumbers{
public static void main (String args[]){
String primeNo = "";
int sum=0;
int j=0;
System.out.println("Prime nums are:" );
for (int i = 1; i < 100; i++){ {
for ( j = 2; j < i; j++){
if (i % j == 0) {
break;
}
}
if (i == j) {
primeNo += i + " ";
sum+=i;
}
}
}
System.out.println(primeNo);
System.out.println("Sum of Prime Numbers: "+sum);
}
}

Thanks

Hi friend Try this code....... *import java.io.; class today2 { public static void main(String args[])throws IOException { BufferedReader obg=new BufferedReader(new InputStreamReader(System.in)); String str=obg.readLine(); int num=Integer.parseInt(str); int sum=0; //int test=5; for(int i=2;i<=num;i++) { if(num%i==0) { sum=sum+i; } } System.out.println("Result"+sum); } }**
