I'm having trouble figuring out what I'm doing wrong that I'm getting the error no line found. Here is my code. I'm having the problem on line 120 and 19

well, at a quick guess, there are no more lines in the file you're reading...

[John Jai]

Before reading next line of the Scanner, check whether they exist using hasNextLine() method. So all your below nextLine() should have a hasNextLine() check and the nextInt() should have hasNextInt() check.

dName = infile.nextLine();
dRoute = infile.nextLine();
dInteraction = infile.nextLine();
amount = infile.nextInt();
nfile.nextLine();

Thank you that helped!
