用Java写一个修改员工信息的代码

以下是一个修改员工信息的Java示例代码：

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

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

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

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public double getSalary() {
        return salary;
    }

    public void setSalary(double salary) {
        this.salary = salary;
    }

    public String toString() {
        return "Name: " + name + ", Address: " + address + ", Age: " + age + ", Salary: " + salary;
    }

    public static void main(String[] args) {
        List<Employee> employees = new ArrayList<>();
        employees.add(new Employee("John Doe", "123 Main St.", 35, 50000));
        employees.add(new Employee("Jane Smith", "456 Oak St.", 28, 40000));

        Scanner input = new Scanner(System.in);
        System.out.print("Enter the name of the employee you want to modify: ");
        String name = input.nextLine();

        for (Employee employee : employees) {
            if (employee.getName().equalsIgnoreCase(name)) {
                System.out.println("Current information: " + employee.toString());

                System.out.print("Enter the new address: ");
                String address = input.nextLine();
                employee.setAddress(address);

                System.out.print("Enter the new age: ");
                int age = input.nextInt();
                employee.setAge(age);

                System.out.print("Enter the new salary: ");
                double salary = input.nextDouble();
                employee.setSalary(salary);

                System.out.println("Updated information: " + employee.toString());
            }
        }
    }
}

这个示例代码创建了一个 `Employee` 类来表示员工信息。在 `main` 方法中，它首先创建了两个初始员工，然后要求用户输入要修改的员工的姓名。然后，它遍历员工列表，找到匹配的员工，并要求用户输入新的地址、年龄和薪水。最后，它打印出更新后的员工信息。
