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();
}}}

Write the output for the following: String s="Today is Test" ; System.out.println(s.indexOf('T')); System.out.println(s.substring(0,7) + " " +"Holiday"); According to me, the answer should be:Today is Holiday. But the marking scheme says that it is:Today i Holiday [OR] Today Holiday Pls explain which is correct, and WHY TF are two answers being accepted?

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?

Can someone give me the order of logical, relational, and arithmetic operators?
