arrangement, array (programming)

JLPT N1

Character Breakdown

Meaning and Usage

"配列" (はいれつ) primarily refers to an arrangement or sequence of items. In everyday Japanese, it can mean any ordered lineup or arrangement, but it is most commonly used in technical contexts, especially programming, where it means "array" — a data structure consisting of elements arranged in a specific order.

Common Contexts

In programming, "配列" is fundamental for storing multiple values under one variable name, accessed by indices. It is often discussed with verbs like "作る" (to create), "操作する" (to manipulate), and "ソートする" (to sort).

Collocations and Patterns

  • 配列を作る: to create an array
  • 配列の要素: elements of an array
  • 配列の順番: the order of the array
  • 配列をソートする: to sort an array

Usage Notes

When using "配列," it is important to distinguish it from similar words like "並び" (ならび), which means a general lineup or order but is less technical. "配列" implies a structured, often fixed, sequence, especially in programming or formal arrangements.

Common Mistake

Learners sometimes confuse "配列" with "配る" (くばる), which means "to distribute." Remember that "配列" is a noun meaning "arrangement" or "array," not a verb.
