本文从比较排序相关的两个接口(Comparable和Comparator)讲起,并以代码实例的形式,讲解了Array、List、Stream排序的方法,这应该可以覆盖大部分Java排序的使用场景。 对于其它集合类如Set和Map,一样可以进行排序处理,可以将它们转化为Stream然后再进行排序。
import java.util.Arrays; public class Sorting { public static void main(String args[]) { String[] strNames = new String[] { "Beans", "Jelly", "Drive", "Language", "Mark", "Run" }; Arrays.sort(strNames); System.out.println("String array after sorting:"); for (...

I made this program which sorts the elements of an array in an ascending order and then prints out the sorted array. #include <stdio.h> int main() { int size, array[1000]; scanf("%d", &size); for (int i=0; i<size; i++) { scanf("%d", array[i]); } int count, max, po...
Choose a pivot element from the array. Partition the array into two sub-arrays, one containing elements smaller than the pivot and the other containing elements larger than the pivot. Sort the two sub-arrays recursively using quicksort. Combine the two sorted sub-arrays. The horizontal lines ar...
简说排序 排序是极其常见的使用场景,因为在生活中就有很多这样的实例。国家GDP排名、奥运奖牌排名、明星粉丝排名等,各大排行榜,给人的既是动力,也是压力。 而讲到排序,就会有各种排序算法和相关实现,本文不讲任何排序算法,而只专注于讲使用。通过实例给大家展示,我们可以了解怎样使用既有的工具进行排序。Linux之父说...

With a Big-O time of O(n^2), Bubble Sort is not very performant so not used very often. However, I found implementing it myself to be a good coding exercise, and I learned about using true/false flags in a while loop to determine the end of a program. ...
