请用java定义一个Teacher类,有五个成员,name,age,sex,email,number。然后创建改类的构造函数,用于初始化上述5个变量

public class Teacher {
String name;
int age;
String sex;
String email;
int number;
public Teacher(String name, int age, String sex, String email, int number) {
this.name = name;
this.age = age;
this.sex = sex;
this.email = email;
this.number = number;
}
}

设计一个基类Person, 包含name、sex和age3个私有数据成员,然后由它派 生出Student类 和 Teacher类,其中Student类中新增学号、 成绩两个私有数据成 员,Teacher类中新增院系 工号、工资3个私有数据成员。另外,Student类和 Teacher类中均有相应的用于数据输入输出的公共接口函数,请编程实现;
下面是实现的代码:
```cpp
#include <iostream>
#include <string>
using namespace std;
class Person {
private:
string name;
char sex;
int age;
public:
void input() {
cout << "请输入姓名:";
cin >> name;
cout << "请输入性别(男/女):";
cin >> sex;
cout << "请输入年龄:";
cin >> age;
}
void output() const {
cout << "姓名:" << name << endl;
cout << "性别:" << sex << endl;
cout << "年龄:" << age << endl;
}
};
class Student : public Person {
private:
string id;
float score;
public:
void input() {
Person::input();
cout << "请输入学号:";
cin >> id;
cout << "请输入成绩:";
cin >> score;
}
void output() const {
Person::output();
cout << "学号:" << id << endl;
cout << "成绩:" << score << endl;
}
};
class Teacher : public Person {
private:
string department;
string job_number;
float salary;
public:
void input() {
Person::input();
cout << "请输入院系:";
cin >> department;
cout << "请输入工号:";
cin >> job_number;
cout << "请输入工资:";
cin >> salary;
}
void output() const {
Person::output();
cout << "院系:" << department << endl;
cout << "工号:" << job_number << endl;
cout << "工资:" << salary << endl;
}
};
int main() {
Student s;
s.input();
s.output();
Teacher t;
t.input();
t.output();
return 0;
}
```
在上面的代码中,我们定义了一个基类 `Person`,包含了 `name`、`sex` 和 `age` 三个私有数据成员,以及两个公有接口函数 `input` 和 `output`,用于输入和输出数据。然后我们定义了两个派生类 `Student` 和 `Teacher`,它们分别新增了学号、成绩和院系、工号、工资三个私有数据成员,并且重载了 `input` 和 `output` 函数。
在 `main` 函数中,我们分别创建了一个 `Student` 对象和一个 `Teacher` 对象,并调用它们的 `input` 和 `output` 函数来输入和输出数据。
综合应用Python程序设计的知识实现下面要求。 (1)设计一个Person类,类变量有id,成员变量有name、sex、age、height、weight (2)实现成员方法1:打印输出属性值 (3)实现静态方法:输出类变量id的值 (4)在Person类中重载__repr__方法 (5)设计子类学生Student(继承Person类),成员属性除了name、sex、age、height、weight之外,增加学号student_number,年级grade,并重写成员方法1,打印所有的属性值 (6)学生的集合类StudentList,它可以承载多名学生信息,并重载索引和切片的方法(__getitem__、__setitem__、__delitem__) (7)设计子类教师Teacher(继承Person类),成员属性除了name、sex、age、height、weight之外,增加教学teach,管理manage,并重写成员方法1,打印所有的属性值 (8)在Teacher类中,对属性age重载__ge__方法 (9)期待同学们设计实现其他成员方法 (10)系统功能完整,程序运行稳定,打包成独立的exe文件
以下是 Python 程序设计的实现:
```python
class Person:
id = 0
def __init__(self, name, sex, age, height, weight):
self.name = name
self.sex = sex
self.age = age
self.height = height
self.weight = weight
Person.id += 1
def __repr__(self):
return f"{self.__class__.__name__}(name='{self.name}', sex='{self.sex}', age={self.age}, height={self.height}, weight={self.weight})"
def print_info(self):
print(f"Name: {self.name}")
print(f"Sex: {self.sex}")
print(f"Age: {self.age}")
print(f"Height: {self.height}")
print(f"Weight: {self.weight}")
@staticmethod
def print_id():
print(f"ID: {Person.id}")
class Student(Person):
def __init__(self, name, sex, age, height, weight, student_number, grade):
super().__init__(name, sex, age, height, weight)
self.student_number = student_number
self.grade = grade
def __repr__(self):
return f"{self.__class__.__name__}(name='{self.name}', sex='{self.sex}', age={self.age}, height={self.height}, weight={self.weight}, student_number='{self.student_number}', grade={self.grade})"
def print_info(self):
super().print_info()
print(f"Student Number: {self.student_number}")
print(f"Grade: {self.grade}")
class Teacher(Person):
def __init__(self, name, sex, age, height, weight, teach, manage):
super().__init__(name, sex, age, height, weight)
self.teach = teach
self.manage = manage
def __repr__(self):
return f"{self.__class__.__name__}(name='{self.name}', sex='{self.sex}', age={self.age}, height={self.height}, weight={self.weight}, teach='{self.teach}', manage='{self.manage}')"
def print_info(self):
super().print_info()
print(f"Teach: {self.teach}")
print(f"Manage: {self.manage}")
def __ge__(self, other):
return self.age >= other.age
class StudentList:
def __init__(self, *students):
self.students = list(students)
def __getitem__(self, index):
return self.students[index]
def __setitem__(self, index, value):
self.students[index] = value
def __delitem__(self, index):
del self.students[index]
```
你可以使用 `pyinstaller` 将 Python 程序打包成独立的 exe 文件,具体的操作可以参考官方文档:https://pyinstaller.readthedocs.io/en/stable/usage.html
