Re: Array and counter in for loop
You can set the size of the array large enough to hold the data.
You need to use the number of used slots in the array to control the looping through the array.
Remember that the max index will be...
Re: Array and counter in for loop
Does fractions[i] have the null value? Why does the code assume it has a valid value?
What is the value of i when the error happens? Does the array have some empty slots in it?
Re: Array and counter in for loop
What statement has the variable with the null value? What variable has the null value?

Call hasNextLine() before every call to nextLine()
Hint: the terminating condition in a for loop can have multiple sub parts:
for(int i=0; (i < 10) && (x > 8); i++) {
