Java Series Programs
Write a program in Java to find the sum of the following series:
S = a + (a/2!) + (a/3!) + (a/4!) + ……. + (a/n!)
Answer
import java.util.Scanner;
public class KboatSeries
{
public void computeSum() {
Scanner in = new Scanner(System.in);
System.out.print("Enter a: ");
int a = in.nextInt();
System.out.print("Enter n: ");
int n = in.nextInt();
double sum = 0;
for (int i = 1; i <= n; i++) {
double f = 1;
for (int j = 1; j <= i; j++) {
f *= j;
}
sum += a / f;
}
System.out.println("Sum=" + sum);
}
}
