;I understood you until the given index part. I have tried to do it the way you discussed it but have gone nowhere and i can't tell if my syntax is wrong or just my logic. Here's what it looks like:
public class Eleven {
public static void main(String[] args) {
Scanner key = new Scanner(System.in);
String number = key.nextLine();
String y = alternatingSum(number);
//System.out.print
}
public static String alternatingSum(String number) {
for(int i=0; i<number.length(); i++){
int a = Integer.parseInt(number.charAt(i));
int b=0;
b= a+b;
int d= Integer.parseInt(number.charAt(i+1));
int f=0;
f= d+f;
}
return number; }
}
I can't see where I'm going wrong.
You're initializing f and b in the loop and doing nothing with them. parseInt just reads the character in number at that index, and returns the integer it represents - it doesn't do anything to number itself. Yet you're returning number.I understood you until the given index part. I have tried to do it the way you discussed it but have gone nowhere and i can't tell if my syntax is wrong or just my logic.

In Intellij press ctrl+q and the documentation for the current item in focus will be shown.
It'll show you exactly what happens when and why it happens.
if(i%16==0)Okay so I have finally got my code to print things out but I can't get it to pump out the right answers.
Here are my test cases:
919293949596979899= 36
9999999999=0
And my codes look like this:
public class Eleven {
public static void main(String[] args) {
Scanner key = new Scanner(System.in);
String number = key.nextLine();
String y = alternatingSum(number);
System.out.print
}
public static String alternatingSum(String number) {
int answer = 0;
int factor = -1;
String z="";
for (int i = 0; i <= number.length(); i++) {
answer += factor * Integer.parseInt(number.substring(0, 2));
number = Integer.toString(answer);
System.out.print(number);
}
return number;
}
}
Thank you tempest03 and everyone else for helping me out so much I couldn't do this without you. Please help me out to the homestretch. Also I don't know where to look to get the documentation. I'm using Jetbrain's IDEA compiler thing and when I use the quick documentation rule, it doesn't do anything.
