Attempting to read and add all integers from certain files.

[round belfry]

I am using a method to read and add the sums of an individual file. I am just stuck on syntax of adding numbers in a file together.

public static int sumFileContents(String fileName) throws IOException {
FileInputStream myFile = new FileInputStream(fileName);
while (scnr.hasNextInt()) {
int sum = (whats the syntax here? int + next int + next int etc);
}
return sum;

You would need to declare the int before the while loop

Than you can use the += operator to add the current line value to the existing variable

[round belfry]

public static int sumFileContents(String fileName) throws IOException {
FileInputStream myFile = new FileInputStream(fileName);
int sum;
while (scnr.hasNextInt()) {
sum += scnr.nextInt();
}
return sum;
}

its just telling me that sum is no longer initialized now

Yeah, you need to give it a start value
