Question about the task Sorting even numbers from a file
Java Core, Level 3, Lesson 11
Under discussion
I struggled with this task a lot before giving up...Why does this task insist on FileInputStream? After doing a quick Google search it became patently obviously that most people use scanner to read integers for a file - I did it this way and it seemed to work. But I'll never know for sure because the task insists on using FileInputStream instead.
