Question about the task Longest string
Java Syntax, Level 7, Lesson 6
Archived
It is already working. I used the help option to check the right answer. But I still didn't understand why we needed to use for loop twice and how we compared the String according to its number of letters??? Can anyone explain please with the most easiest language as you can.

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?
