Question about the task One large array and two small ones
Java Syntax, Level 7, Lesson 4

Created 2 arrays of 10 but still failed I'm not sure what I did here because when I print both of the smaller arrays I get "two small arrays of 10 numbers each". I'm also not sure how it is possible to meet 1, 2, & 4, and still not meet 3.
