java编写一个employee 类

好的，下面是一个简单的Java Employee类的示例：

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;
    }

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

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

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

    public void printEmployee() {
        System.out.println("Name: " + name);
        System.out.println("Age: " + age);
        System.out.println("Salary: " + salary);
    }
}

这个Employee类有三个私有属性：name、age和salary，以及一个构造函数和一些getter和setter方法。它还有一个printEmployee方法，用于打印Employee对象的属性。您可以根据需要进行修改和扩展。
