Write a method called negativeSum that accepts a Scanner reading input from a file containing a series of integers, and print a message to the console indicating whether the sum starting from the first number is ever negative. You should also return true if a negative sum can be reached and false if not. For example, suppose the file contains the following text:
38 4 19 −27 −15 −3 4 19 38
Your method would consider the sum of just one number (38), the first two numbers (38 + 4), the first three numbers (38 + 4 + 19), and so on to the end. None of these sums is negative, so the method would produce the following output and return false:
no negative sum
If the file instead contains the following numbers:
14 7 −10 9 −18 −10 17 42 98
The method finds that a negative sum of −8 is reached after adding the first six numbers. It should output the following to the console and return true:
sum of −8 after 6 steps
