We assume the array is sorted, but if we're proven wrong while sorting (if a swap happens), we go through another iteration. Our function enters a while loop in which it goes through the entire array swapping as needed. We're going to implement Bubble Sort in a similar way we've laid it out in words. If you'd like to read a detailed, dedicated article for Bubble Sort, we've got you covered! Implementation The reason this algorithm is called Bubble Sort is because the numbers kind of 'bubble up' to the 'surface.' If you go through our example again, following a particular number (4 is a great example), you'll see it slowly moving to the right during the process.ДЄll numbers move to their respective places bit by bit, left to right, like bubbles slowly rising from a body of water. Here are the steps for sorting an array of numbers from least to greatest:Д¤ 2 1 5 3: The first two elements are in the wrong order, so we swap them.Дў 4 1 5 3: The second two elements are in the wrong order too, so we swap.Дў 1 4 5 3: These two are in the right order, 4 < 5, so we leave them alone.Дў 1 4 3 5: Here's the resulting array after one iteration.Д«ecause at least one swap occurred during the first pass (there were actually three), we need to go through the whole array again and repeat the same process.Д«y repeating this process, until no more swaps are made, we'll have a sorted array. We know that all elements are in order when we manage to do the whole iteration without swapping at all - then all elements we compared were in the desired order with their adjacent elements, and by extension, the whole array. A example to find out difference seconds between two LocalDateTime. Period Measures time in years, months and days. Duration Measures time in seconds and nanoseconds.

This process repeats from the beginning of the array until all elements are in order. Few examples to show you how to use Java 8 Duration, Period and ChronoUnit objects to find out the difference between dates. Bubble Sort ExplanationД«ubble sort works by swapping adjacent elements if they're not in the desired order. You may change the model time units whenever. Note: This article will not be dealing with concurrent sorting, since it's meant for beginners. AnyLogic supports all popular time units: milliseconds, seconds, minutes, hours, days, weeks, months, years. The list of algorithms you'll learn here is by no means exhaustive, but we have compiled some of the most common and most efficient ones to help you get started, We'll be analyzing their time complexity in order to compare them and see which ones perform the best.

There are various sorting algorithms, and they're not all equally efficient.

If you're interested in how sorting works, we'll cover various algorithms, from inefficient but intuitive solutions, to efficient algorithms which are actually implemented in Java and other languages. You can even define your own criteria, and we'll go into practical ways of doing that by the end of this article. You can use various ordering criteria, common ones being sorting numbers from least to greatest or vice-versa, or sorting strings lexicographically. Sorting data means arranging it in a certain order, often in an array-like data structure.
