java如何实现一个数组从小到大排序的操作呢?

实现思路:
    使用两个for循环
        借助if判断数据进行排序操作

import java.util.Arrays;
public class ArraySort {
 
    public static void SelectSort(int[] needSortArray) {
        int tmp = 0;
        for (int i = 0; i < needSortArray.length; i++) {
            for (int j = i + 1; j < needSortArray.length; j++) {
                if (needSortArray[j] < needSortArray[i]) {
                    tmp = needSortArray[i];
                    needSortArray[i] = needSortArray[j];
                    needSortArray[j] = tmp;
                }
            }
        }
    }
 
    public static void main(String[] args) {
        int[] a1 = {32,2,11,9,22,66,8,11,19};
        SelectSort(a1);
        System.out.println(Arrays.toString(a1)); 
    }
}
