记一次随便排序算法

public class F {
    public static void main(String[] args) {
        int[] as = {1,6,8,9,4,6,7,5,3,1,24,5,67,4};
        for (int i = 0; i < as.length; i++) {
            System.out.print(as[i]+" ");
        }
        System.out.println();
        for (int i = 0; i < as.length; i++) {
            for (int j = i; j < as.length; j++) {
                if (as[i] > as[j]){
                    as[i] = as[i] + as[j];
                    as[j] = as[i] - as[j];
                    as[i] = as[i] - as[j];
                }
