Looking for some insight Guys although I've solved the task I don't understand why the following solution doesn't work. I know I can't use a ' for loop ' to remove elements but this seems to make sense ,but it doesn't work. Iv'e tried googling with no satisfactory answers. Why doesn't this work : Iterator

Question about the task Finding data inside a file
Java Core, Level 8, Lesson 11
Resolved
How does the pattern look like?The task describes the pattern as: id productName price quantity. So how I picture it is this (for example): 1 iPhone 2xs 1999.99 3. So if the name (iPhone 2xs) has spaces and numbers in it, how can I distinguish betwen what is what, I mean where the name finishes and the ''price'' starts?
