员工按照工资从大到小排列，java

您好，可以使用Java中的Arrays类的sort方法来对员工按照工资从大到小排序，示例代码如下：

import java.util.Arrays;

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

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

    public String getName() {
        return name;
    }

    public double getSalary() {
        return salary;
    }

    public static void main(String[] args) {
        Employee[] employees = {new Employee("Alice", 5000), new Employee("Bob", 7000), new Employee("Charlie", 6000)};
        
        //按照工资从大到小排序
        Arrays.sort(employees, (e1, e2) -> Double.compare(e2.getSalary(), e1.getSalary()));
        
        //输出排序结果
        for (Employee employee : employees) {
            System.out.println(employee.getName() + " " + employee.getSalary());
        }
    }
}

运行结果：

Bob 7000.0
Charlie 6000.0
Alice 5000.0

这里使用了lambda表达式来定义比较器，也可以使用实现Comparator接口的类来定义比较器。
