示例代码如下

package interview;

import java.util.Arrays;
import java.util.Random;

//冒泡排序法实现10个100内的随机数字的排序
public class BubbleSort {
    public static void main(String[] args) {
        //数据准备
        int[] arr = new int[10];
        for (int i = 0; i < arr.length; i++) {
            Random random = new Random();
            arr[i] = random.nextInt(100);
        }
        System.out.println(Arrays.toString(arr));
        
        System.out.println("************冒泡排序开始**************");
        bubbleSort(arr);
        System.out.println("************冒泡排序开始**************");
        System.out.println(Arrays.toString(arr));
    }
    //冒泡排序
    public static void bubbleSort(int[] arr) {
        for (int i = 0; i < arr.length - 1; i++) {
            for (int j = 0; j < arr.length - i - 1; j++) {
                if (arr[j] > arr[j + 1]) {
                    int temp = arr[j];
                    arr[j] = arr[j + 1];
                    arr[j + 1] = temp;
                }
            }
            System.out.println(Arrays.toString(arr));
        }
    }
}

代码执行结果如下:

[91, 69, 11, 90, 29, 25, 77, 63, 47, 37]
