（2）某学校有3类员工：教师、行政人员、教师兼行政人员，共有的信息包括编号、姓名、性别和职工类别。工资计算方法如下。 教师：基本工资+课时数×课时补贴。 行政人员：基本工资+行政补贴。 教师兼行政人员：基本工资+课时数×课时补贴+行政补贴。 分析以上信息，定义人员抽象类，派生不同类型的员工，并完成工资的计算。

人员抽象类定义：

public abstract class Employee {
    private String id;
    private String name;
    private String gender;
    private String type;

    public Employee(String id, String name, String gender, String type) {
        this.id = id;
        this.name = name;
        this.gender = gender;
        this.type = type;
    }

    public String getId() {
        return id;
    }

    public String getName() {
        return name;
    }

    public String getGender() {
        return gender;
    }

    public String getType() {
        return type;
    }

    public abstract double getSalary();
}

教师类：

public class Teacher extends Employee {
    private int hour;
    private double allowancePerHour;

    public Teacher(String id, String name, String gender, String type, int hour, double allowancePerHour) {
        super(id, name, gender, type);
        this.hour = hour;
        this.allowancePerHour = allowancePerHour;
    }

    public int getHour() {
        return hour;
    }

    public double getAllowancePerHour() {
        return allowancePerHour;
    }

    @Override
    public double getSalary() {
        return hour * allowancePerHour;
    }
}

行政人员类：

public class Administrator extends Employee {
    private double allowance;

    public Administrator(String id, String name, String gender, String type, double allowance) {
        super(id, name, gender, type);
        this.allowance = allowance;
    }

    public double getAllowance() {
        return allowance;
    }

    @Override
    public double getSalary() {
        return allowance;
    }
}

教师兼行政人员类：

public class TeacherAdministrator extends Employee {
    private int hour;
    private double allowancePerHour;
    private double allowance;

    public TeacherAdministrator(String id, String name, String gender, String type, int hour, double allowancePerHour, double allowance) {
        super(id, name, gender, type);
        this.hour = hour;
        this.allowancePerHour = allowancePerHour;
        this.allowance = allowance;
    }

    public int getHour() {
        return hour;
    }

    public double getAllowancePerHour() {
        return allowancePerHour;
    }

    public double getAllowance() {
        return allowance;
    }

    @Override
    public double getSalary() {
        return hour * allowancePerHour + allowance;
    }
}

使用示例：

public class Test {
    public static void main(String[] args) {
        Employee e1 = new Teacher("001", "张三", "男", "教师", 40, 50);
        Employee e2 = new Administrator("002", "李四", "女", "行政人员", 5000);
        Employee e3 = new TeacherAdministrator("003", "王五", "男", "教师兼行政人员", 40, 50, 5000);

        System.out.println(e1.getName() + " 的工资为：" + e1.getSalary());
        System.out.println(e2.getName() + " 的工资为：" + e2.getSalary());
        System.out.println(e3.getName() + " 的工资为：" + e3.getSalary());
    }
}
