冒泡排序

前言：跟helloworld一样，不解释

import java.util.Arrays;

public class BubbleSort {
    public static void main(String[] args) {
        int[] array = new int[]{7, 1, 5, 8, 6, 2, 3, 9, 4};
        int len = array.length;
        boolean flag = true;
        for (int i = 0; i < len - 1 && flag; i++) {
            flag = false;
            for (int j = i + 1; j < len; j++) {
                if (array[i] > array[j]) {
                    int temp = array[i];
                    array[i] = array[j];
                    array[j] = temp;
                    flag = true;
                }
            }
        }
        System.out.println("从小到大排序后的结果是:");
        System.out.println(Arrays.toString(array));

    }
}
