Java:对列表的随机数字范围进行排序+组织它(冒泡排序)+获取最大的生成数字

Question

我正在努力完成一个项目，非常感谢任何人的帮助。提前致谢。

要求: 1. 打印一个包含 (1-100) 范围内的 10 个随机数的列表，完成。 2、按照月牙顺序打印生成的列表； 3. 打印生成列表中最大的数字。

以下是我所做的以及我陷入困境的地方:

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

public class Project {

    public static void main(String[] args) {

        list(0, 0);
        printMax(0);
        //bubbleSort();
        System.out.print("The sorted list is: "); //???

    }

    private static void list(int min, int max) {

        int[] numbers = new int[10];
        // Generates 10 Random Numbers in the range 1 -100
        for (int i = 0; i<numbers.length; i++) {
            numbers[i] = (int)(Math.random() * 100 + 1);
        }
        System.out.println("The unsorted list is: " + Arrays.toString(numbers));
        return;

    }

    private static void printMax(int...numbers) {
        int result = numbers[0];

        for (int i = 1; i<numbers.length; i++) {

            if (numbers[i] > result)
                result = numbers[i];
        }
        System.out.println("The largest value is " + numbers);
        return;
    }

    public static void bubbleSort(int[] list) {
        int temp;

        for (int i = list.length - 1; i > 0; i--) {
            for (int j = 0; j<i; j++) {
                if (list[j] > list[j + 1]) {
                    temp = list[j];
                    list[j] = list[j + 1];
                    list[j + 1] = temp;
                }
            }
        }
    }
}
