This is from the 2016 marking scheme...(Q7)
How has variable 'i' been used in the second method too? Isn't a local variable?
And couldn't we just have declared it before void SumSeries(int n, double x)???

import java.util.*;
class Q7 {
void SumSeries(int n, double x) {
double sum=0.0d;
int i;
for(i=1;i<=n;i++)
{ if (i%2==0 )
sum=sum-x/(double)i;
else
sum=sum+x/(double)i; }
System.out.println("sum="+sum); }
void SumSeries() {
int s=0, p=1;
for(int i=1;i<=20;i++) {
p=p*i;
s=s+p; }
System.out.println("sum="+s); }
public static void main(String args[]) {
Q7 obj=new Q7();
obj.SumSeries(5,2.0);
obj.SumSeries();
}}}
