声明一个整形数组，用冒泡法降序排列声明2个对象，加入到Arraylist中用增加for循环输出员工信息

声明一个整型数组并使用冒泡排序法进行降序排列，然后将两个对象添加到ArrayList中，最后使用for-each循环输出员工信息的步骤如下：

1. 声明一个整型数组：

int[] numbers = {3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5};

2. 使用冒泡排序算法对数组进行降序排列：

for (int i = 0; i < numbers.length - 1; i++) {
    for (int j = 0; j < numbers.length - 1 - i; j++) {
        if (numbers[j] < numbers[j + 1]) {
            // 交换两个元素的位置
            int temp = numbers[j];
            numbers[j] = numbers[j + 1];
            numbers[j + 1] = temp;
        }
    }
}

3. 创建一个Employee类，并声明两个Employee对象：

class Employee {
    String name;
    int age;
    String department;

    public Employee(String name, int age, String department) {
        this.name = name;
        this.age = age;
        this.department = department;
    }

    @Override
    public String toString() {
        return "Employee{" +
                "name='" + name + '\'' +
                ", age=" + age +
                ", department='" + department + '\'' +
                '}';
    }
}

Employee emp1 = new Employee("张三", 30, "研发部");
Employee emp2 = new Employee("李四", 28, "市场部");

4. 将两个Employee对象添加到ArrayList中：

ArrayList<Employee> employees = new ArrayList<>();
employees.add(emp1);
employees.add(emp2);

5. 使用for-each循环遍历ArrayList并输出员工信息：

for (Employee employee : employees) {
    System.out.println(employee);
}
