Question 4.9 : Write a program in Java to find the sum of the series 1!/1+2!/2+3!/3+4!/4+5!/5 using the function.
Expected Output :
The sum of the series is : 34
Solution:
package lab4problem9;
public class Lab4Problem9 {
public static void main(String[] args) {
int x = sumOfSeries();
System.out.println("The sum of the series is : "+x);
}
static int sumOfSeries() {
double a = 1, z = 0;
for (double i = 1; i <= 5; i++) {
for (double j = 1; j <= i; j++) {
a = a * j;
}
z = z + a/i;
a = 1;
}
return (int) z;
}
}
