This tutorial launches a short series introducing data structures and algorithms. In Part 1, you’ll learn what a data structure is and how data structures are classified.

Data structures and algorithms in Java, Part 2 introduced a variety of techniques for searching and sorting one-dimensional arrays, which are the simplest arrays.

Treating it like an array assigns each value to the sub-variable in the same order as the struct was defined. Designated initializers can be arbitrarily assigned by name.
