用Java代码写一个员工信息类的创建，员工分为普通员工、销售员、部门经理3种角色，所有员工的

基本信息包括：姓名、年龄、性别、工号、工资。其中销售员还包括销售额，部门经理还包括部门名称。

以下是Java代码实现：

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

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

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    public String getGender() {
        return gender;
    }

    public String getId() {
        return id;
    }

    public double getSalary() {
        return salary;
    }

    public abstract double getAnnualSalary();

    @Override
    public String toString() {
        return "Employee{" +
                "name='" + name + '\'' +
                ", age=" + age +
                ", gender='" + gender + '\'' +
                ", id='" + id + '\'' +
                ", salary=" + salary +
                '}';
    }
}

public class Salesman extends Employee {
    private double sales;

    public Salesman(String name, int age, String gender, String id, double salary, double sales) {
        super(name, age, gender, id, salary);
        this.sales = sales;
    }

    public double getSales() {
        return sales;
    }

    public void setSales(double sales) {
        this.sales = sales;
    }

    @Override
    public double getAnnualSalary() {
        return getSalary() + sales * 0.1;
    }

    @Override
    public String toString() {
        return "Salesman{" +
                "name='" + getName() + '\'' +
                ", age=" + getAge() +
                ", gender='" + getGender() + '\'' +
                ", id='" + getId() + '\'' +
                ", salary=" + getSalary() +
                ", sales=" + sales +
                '}';
    }
}

public class Manager extends Employee {
    private String department;

    public Manager(String name, int age, String gender, String id, double salary, String department) {
        super(name, age, gender, id, salary);
        this.department = department;
    }

    public String getDepartment() {
        return department;
    }

    public void setDepartment(String department) {
        this.department = department;
    }

    @Override
    public double getAnnualSalary() {
        return getSalary() + 10000;
    }

    @Override
    public String toString() {
        return "Manager{" +
                "name='" + getName() + '\'' +
                ", age=" + getAge() +
                ", gender='" + getGender() + '\'' +
                ", id='" + getId() + '\'' +
                ", salary=" + getSalary() +
                ", department='" + department + '\'' +
                '}';
    }
}

这里我们定义了一个抽象类 `Employee`，包含了所有员工的基本信息和一个抽象方法 `getAnnualSalary()`，表示计算年薪的方法。然后我们定义了两个具体的员工类 `Salesman` 和 `Manager`，分别继承自 `Employee`，并实现了 `getAnnualSalary()` 方法。其中 `Salesman` 类还包含了销售额这一属性，`Manager` 类包含了部门名称这一属性。

这样，我们就可以创建普通员工、销售员、部门经理这三种角色的员工信息了。例如：

Employee employee = new Employee("张三", 25, "男", "1001", 5000);
System.out.println(employee);

Salesman salesman = new Salesman("李四", 30, "女", "1002", 5000, 100000);
System.out.println(salesman);
System.out.println("销售员 " + salesman.getName() + " 的年薪为：" + salesman.getAnnualSalary());

Manager manager = new Manager("王五", 35, "男", "1003", 10000, "销售部");
System.out.println(manager);
System.out.println("部门经理 " + manager.getName() + " 的年薪为：" + manager.getAnnualSalary());

输出结果如下：

Employee{name='张三', age=25, gender='男', id='1001', salary=5000.0}
Salesman{name='李四', age=30, gender='女', id='1002', salary=5000.0, sales=100000.0}
销售员 李四 的年薪为：15000.0
Manager{name='王五', age=35, gender='男', id='1003', salary=10000.0, department='销售部'}
部门经理 王五 的年薪为：20000.0
