- Converting array to list in Java - Stack Overflow

- Whats the simplest way to print a Java array? - Stack Overflow

- How to merge two arrays in JavaScript and de-duplicate items

- Concatenating two one-dimensional NumPy arrays - Stack Overflow

- Why do we use arrays instead of other data structures?
That is where arrays get beat, they provide a linear O (N) search time, despite O (1) access time This is an incredibly high level overview on data structures in memory, skipping over a lot of details, but hopefully it illustrates an array's strength and weakness compared to other data structures
