In this issue, the editor will bring you about how to use Sort to sort in Java. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

1. Array Sort sorting

Sort in ascending order, using the Arrays.Sort method directly, for example:

Import java.util.Arrays;public class Solution {public static void main (String [] args) {int [] array = {10, 3, 6, 1, 4, 5, 9}; / positive sort Arrays.sort (array) / / merge sort is used when the number of arrays is greater than 286 and continuity is good. If it is less than 47, insert sort is used, and System.out.println ("ascending sort:") is used for the rest; for (int num: array) {System.out.println (sort);}

Sort in descending order, which can be looped in reverse order in the case of outputting only the array, for example:

Import java.util.Arrays;public class Solution {public static void main (String [] args) {int [] array = {10, 3, 6, 1, 4, 5, 9}; / positive sort Arrays.sort (array) / / merge sort is used when the number of arrays is greater than 286 and continuity is good. If it is less than 47, insert sort is used, and System.out.println ("ascending sort:") is used for the rest of the cases; for (int num: array) {System.out.println (sort) } / / sort in reverse / / (1) since no reverse method is provided, you can reverse the output System.out.println ("descending output:"); for (int I = array.length-1; I > = 0; iMube -) {System.out.println (array [I]);}

Sort in descending order, for cases where you need to use an array, you can create a new array and then access the assignment in reverse order, for example:

Import java.util.Arrays;public class Solution {public static void main (String [] args) {int [] array = {10, 3, 6, 1, 4, 5, 9}; / positive sort Arrays.sort (array) / / merge sort is used when the number of arrays is greater than 286 and continuity is good. If it is less than 47, insert sort is used, and System.out.println ("ascending sort:") is used for the rest of the cases; for (int num: array) {System.out.println (sort) } / / sort in reverse / / (1) since no reverse method is provided, you can reverse the output System.out.println ("descending output:"); for (int I = array.length-1; I > = 0; iMube -) {System.out.println (array [I]) } / / (2) or create a new array and save it backwards to the new array int [] descArray = new int [array.length]; for (int I = 0; I < array.length; iArray +) {descArray [I] = array [array.length-I-1];} System.out.println ("New array descending output:") For (int num: descArray) {System.out.println (num);} above is how to use Sort to sort the Java shared by the editor.
