Preface

When using array sorting function in JAVA, there are generally four methods: fast sorting method, bubble sorting method, selective sorting method and insertion sorting method.

The methods are as follows:

1. Quick sort: first of all, the simplest Array.sort is sorted directly:

Public static void main (String [] args) {int [] arr = {4 System.out.println [] arr = {4 int I: arr) {System.out.println (I);}

Click run to output the sorted array numbers.

2, partial sorting method: you can also use Array.sort to select some of the numbers you want to sort, such as sorting the numbers with the subscript number 1: 4, and the order of other numbers remains the same.

Public static void main (String [] args) {int [] arr = {4, int, 3, arr, 1, 2, 9, 3, 0}; Arrays.sort (arr,1,4); for (int I = 0 Tinci)
