This article is part of the free Java 8 course on the Clean code principle. In this article, we'll talk about the Java comparable interface. There is also a nice video to click here. What is the comparable interface for? How should we compare and sort things? This question sounds a little bit confusing, but I hope you will think it over carefully. For example, we have a group of apples: Example 1 How do we sort them? Do we want to sort by weight? If so, is the order from lightest to heaviest or from heaviest to lightest? When we sort them, we need to compare the weight of the two apples over and over again until all the apples are properly lined up. Apple 1 is 2 heavier than Apple? Is it 3 heavier than apples? We need to keep comparing until the sorting is done. The comparable interface can help us achieve this goal. The comparable itself cannot sort objects, but the interface defines the method int CompareTo (T) can. How CompareTo (T) works lets us use the CompareTo () method to
