使用java统计全公司的年龄并且以升序的形式打印出来，统计全公司的薪资并且以降序的形式打印出来

好的，我可以给你一些思路和代码示例。

首先，我们需要定义一个员工类，包含姓名、年龄、薪资等属性。

public class Employee {
    private String name;
    private int age;
    private double salary;

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

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    public double getSalary() {
        return salary;
    }
}

然后，我们可以创建一个员工列表，并向其中添加一些员工信息。

List<Employee> employees = new ArrayList<>();
employees.add(new Employee("张三", 25, 5000));
employees.add(new Employee("李四", 30, 8000));
employees.add(new Employee("王五", 28, 6000));
employees.add(new Employee("赵六", 35, 10000));
employees.add(new Employee("钱七", 24, 4000));

接下来，我们可以使用lambda表达式和Stream API来对员工列表进行统计和排序。

统计年龄的代码示例：

List<Integer> ages = employees.stream()
        .map(Employee::getAge)
        .sorted()
        .collect(Collectors.toList());
System.out.println("按年龄升序排列：" + ages);

统计薪资的代码示例：

List<Double> salaries = employees.stream()
        .map(Employee::getSalary)
        .sorted(Comparator.reverseOrder())
        .collect(Collectors.toList());
System.out.println("按薪资降序排列：" + salaries);

最后，我们可以将年龄和薪资统计的结果打印出来。

完整代码示例如下：

import java.util.ArrayList;
import java.util.Comparator;
import java.util.List;
import java.util.stream.Collectors;

public class Main {
    public static void main(String[] args) {
        List<Employee> employees = new ArrayList<>();
        employees.add(new Employee("张三", 25, 5000));
        employees.add(new Employee("李四", 30, 8000));
        employees.add(new Employee("王五", 28, 6000));
        employees.add(new Employee("赵六", 35, 10000));
        employees.add(new Employee("钱七", 24, 4000));

        List<Integer> ages = employees.stream()
                .map(Employee::getAge)
                .sorted()
                .collect(Collectors.toList());
        System.out.println("按年龄升序排列：" + ages);

        List<Double> salaries = employees.stream()
                .map(Employee::getSalary)
                .sorted(Comparator.reverseOrder())
                .collect(Collectors.toList());
        System.out.println("按薪资降序排列：" + salaries);
    }
}

class Employee {
    private String name;
    private int age;
    private double salary;

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

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    public double getSalary() {
        return salary;
    }
}
