编程题， 用java编写一个名为Person的类和它的子类Employee 具体要求如下: (1)Person类中的属性有:姓名name ( String类型) , 地址address ( String类型) , 电话号码telephone ( String类型) ; (2)Employee类继承Person类，并新建属性:办公室office ( String类型) ,工资wage ( double类型) (3)每个类中分别定义两个构造方法。 (4)在子类中定义主方法，创建子类对象并打印类的部分属性。

以下是Java代码实现：

public class Person {
    private String name;
    private String address;
    private String telephone;

    public Person(String name, String address, String telephone) {
        this.name = name;
        this.address = address;
        this.telephone = telephone;
    }

    public Person() {
        this("", "", "");
    }

    public String getName() {
        return name;
    }

    public String getAddress() {
        return address;
    }

    public String getTelephone() {
        return telephone;
    }
}

public class Employee extends Person {
    private String office;
    private double wage;

    public Employee(String name, String address, String telephone, String office, double wage) {
        super(name, address, telephone);
        this.office = office;
        this.wage = wage;
    }

    public Employee() {
        this("", "", "", "", 0.0);
    }

    public static void main(String[] args) {
        Employee employee = new Employee("张三", "北京市海淀区", "010-12345678", "A101", 10000.0);
        System.out.println("姓名：" + employee.getName());
        System.out.println("地址：" + employee.getAddress());
        System.out.println("电话：" + employee.getTelephone());
        System.out.println("办公室：" + employee.office);
        System.out.println("工资：" + employee.wage);
    }
}

运行结果：

姓名：张三
地址：北京市海淀区
电话：010-12345678
办公室：A101
工资：10000.0
