java编程：定义一个员工类，包含属性“姓名、性别、年龄、月基本工资、月绩效工资”，方法“构造方法、获得姓名、获得性别、获得年龄、获得月基本工资、获得月绩效工资、打印属性全部信息”。 定义一个统计类，包含一个静态方法“工资排序”，方法接收一个员工类数组，对数组中的所有员工按照月基本工资从小到大排序，如果基本工资相同，则按照绩效工资从小到大排序，最后返回排好序的员工数组。 定义一个测试类，在测试类中，创建包含不少于5个员工对象的数组，并且至少有2个员工基本工资相同。利用统计类对基本员工数组进行排序，最后将排好序的数组中员工姓名输出。

员工类：

public class Employee {
    private String name;
    private String gender;
    private int age;
    private double basicSalary;
    private double performanceSalary;

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

    public String getName() {
        return name;
    }

    public String getGender() {
        return gender;
    }

    public int getAge() {
        return age;
    }

    public double getBasicSalary() {
        return basicSalary;
    }

    public double getPerformanceSalary() {
        return performanceSalary;
    }

    public void printInfo() {
        System.out.println("姓名：" + name);
        System.out.println("性别：" + gender);
        System.out.println("年龄：" + age);
        System.out.println("月基本工资：" + basicSalary);
        System.out.println("月绩效工资：" + performanceSalary);
    }
}

统计类：

import java.util.Arrays;

public class Statistics {
    public static Employee[] salarySort(Employee[] employees) {
        Arrays.sort(employees, (e1, e2) -> {
            if (e1.getBasicSalary() != e2.getBasicSalary()) {
                return Double.compare(e1.getBasicSalary(), e2.getBasicSalary());
            } else {
                return Double.compare(e1.getPerformanceSalary(), e2.getPerformanceSalary());
            }
        });
        return employees;
    }
}

测试类：

public class Test {
    public static void main(String[] args) {
        Employee[] employees = new Employee[] {
            new Employee("张三", "男", 25, 3000, 2000),
            new Employee("李四", "女", 22, 2500, 1500),
            new Employee("王五", "男", 28, 2500, 2500),
            new Employee("赵六", "女", 23, 3500, 1800),
            new Employee("孙七", "男", 30, 2500, 1900)
        };
        employees = Statistics.salarySort(employees);
        for (Employee employee : employees) {
            System.out.println(employee.getName());
        }
    }
}
