I believe the code is somehow getting caught in the 'while' loop but have no idea what i'm doing wrong. Please help.

Input text would be file location: C:\Users\IanSP\Desktop\Java\Student.txt

Previous code has written a file in this exact location as it shows in the file location an can be opened physically to show written data.

CodePudding user response：

while (inputFile.hasNext()){
     Num = inputFile.nextDouble();
     Sum = Sum   Num;
}

this part should be this way, need to delete the mark after the while
