Easy method for automorphic number,

into n = in.nextInt();
String s = Integer.to string(n);
int k = n*n;
String s1 = Integer.to string(k);
If(s1.ends with(s))
s.o.pln("automorphic");
else
s.o.pln("not automorphic");

Write a program to assign a full path and file name as given below.Using library functions,extract and output the file path,file name and file extension. Where am I wrong? import java.util.*; class Ex { public static void main(String args[]) { Scanner in = new Scanner(System.in); System.out.println("Enter file name"); String s = "C:\Users\admin\Pictures\flower.jpg"; int m = s.lastIndexOf('.'); System.out.println(" Extension="+(s.substring(m+1)); int j = s.lastIndexOf('\'); System.out.println("Output path ="+s.substring(0,j+1); System.out.println("File name="+(s.substring(j+1,m)); } }

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?

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();
}}}
