I\'m apparently facing an infinite loop on while(input.hasNext())
, as in following code
File file = new File(\"data.txt\");
Scanner input = new Sca
Seems like scanner is reading a non int value from your file and when it does , while(input.hasNext()) will always be true because there is something as an input to scanner but it is not int. So scanner skips reading this non-int value in the inner if(input.hasNextInt()) check.
So scanner does not proceed beyond this element and always return true.
If you want to sum up all the integers in your file then you should modify your code to below:
while(input.hasNext()) {
if(input.hasNextInt()) {
sum += input.nextInt();
}
else
input.next();
}
Just read the non integer elements when scanner encouters it. Hope this clarifies.
