Insertion Sort is one of the simplest and most intuitive sorting algorithms. Instead of dividing data into groups or using complex recursion, it builds the final sorted array one element at a time — much like how you would sort playing cards in your hand.

While it may not be the fastest algorithm for large datasets, its simplicity, stability, and efficiency on small or nearly sorted data make it incredibly useful in practice.

In this article, we’ll explore how Insertion Sort works, implement it in Java, and examine where it shines (and where it doesn’t).
