Stuck In A Loop - Max Value Gets Reset To The Next Value In File

The problem i believe is that I have the max value set to the first value given out, but every time the loop repeats the Max value gets reset to the next value in the file.

Essentially the program is supposed to read a list of credit card transactions and tell the user which transaction is the highest.

Here's the list of the sample file, note that the number of transactions could change that's why i haven't tried simply passing the values to method.

Bicycle 562.90
Groceries 138.43
Hotel 612.00

import java.io.File;
import java.io.IOException;
import java.util.Scanner;
public class CreditCards {
public static void main(String[] args) throws IOException {
String fileName = "C:/Users/David/Desktop/CreditCard.txt";
File inputFile = new File(fileName);
