If y = 10, what is the value of : ++y * (y++ + 5) I think it should be 15 * 12 = 180 but I am getting 176 as the output. Any reason why it does prefix before parentheses when parentheses are above prefix in precedence?

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();
}}}
