Hello everyone, I need some help here. So this program takes an input file that I will post at the bottom with ints.
Assignment:
Write a program that inputs a list of numbers that are arranged into groups of various sizes. The program outputs the sum of the numbers in each group. Each group starts with a one-line descriptive phrase. The phrase can be anything that is not a number. Some groups may have zero number in them.
Problem: Everything runs fine at first and I get my first group sum of -44 which is correct but then i get this
I'm getting an StringIndexOutOfBoundsException
String index out of range: 0 at java.lang.String.charAt(unknown source)
Input file:
Group A
23
-12
29
-84
Group B
-2
-45
-90
123
26
19
-5
-30
9
Group C
Last Group
12
-34
23
47
52
8
Solution should be:
Group 1
Sum = -44
Group 2
Sum = 5
Group 3
Sum = 0
Group 4
Sum = 108
