定义一个teacher类和一个student类

Teacher类：教师类，包含属性姓名、年龄、性别、教授课程、教龄等，以及方法教授课程、布置作业、批改作业等。

Student类：学生类，包含属性姓名、年龄、性别、学号、班级等，以及方法上课、做作业、考试等。

用java代码实现创建一个student类，类内含有姓名、性别和年龄等成员变量，定义获取各变量的方法和思考方法; 创建一个teacher类，类内含有姓名、性别和年龄等成员变量，定义获取各变量的方法和教学方法；创建一个people类，声明两个成员变量分别是student类和teacher类的对象，定义获取student类和teacher类中成员变量及思考和教学的方法；创建一个主类，主类中创建一个student对象，一个teacher对象和一个people对象。输出对象的相关信息。

好的，您的问题已经被记录下来了。

下面是您所要求的Java代码实现：

class Student {
    String name;
    String gender;
    int age;

    public Student(String name, String gender, int age) {
        this.name = name;
        this.gender = gender;
        this.age = age;
    }

    public String getName() {
        return this.name;
    }

    public String getGender() {
        return this.gender;
    }

    public int getAge() {
        return this.age;
    }

    public void study() {
        System.out.println(this.name + " is studying.");
    }
}

class Teacher {
    String name;
    String gender;
    int age;

    public Teacher(String name, String gender, int age) {
        this.name = name;
        this.gender = gender;
        this.age = age;
    }

    public String getName() {
        return this.name;
    }

    public String getGender() {
        return this.gender;
    }

    public int getAge() {
        return this.age;
    }

    public void teach() {
        System.out.println(this.name + " is teaching.");
    }
}

class People {
    Student student;
    Teacher teacher;

    public People(Student student, Teacher teacher) {
        this.student = student;
        this.teacher = teacher;
    }

    public Student getStudent() {
        return this.student;
    }

    public Teacher getTeacher() {
        return this.teacher;
    }

    public void think() {
        System.out.println("I am thinking.");
    }
}

public class Main {
    public static void main(String[] args) {
        Student s = new Student("Tom", "male", 20);
        Teacher t = new Teacher("Jerry", "male", 30);
        People p = new People(s, t);

        System.out.println("Student: " + p.getStudent().getName() + ", " + p.getStudent().getGender() + ", " + p.getStudent().getAge());
        System.out.println("Teacher: " + p.getTeacher().getName() + ", " + p.getTeacher().getGender() + ", " + p.getTeacher().getAge());

        p.getStudent().study();
        p.getTeacher().teach();

        p.think();
    }
}

输出结果如下：

Student: Tom, male, 20
Teacher: Jerry, male, 30
Tom is studying.
Jerry is teaching.
I am thinking.

python 定义一个Person类有name, age, sex的公有成员变量，以及一个showinfor（）的方法对该类的三个属性进行打印。再定义一个Teacher类，该类继承Person类，并且额外新增一个department的公有成员变量，也对Teacher类定义一个showinfor（）的方法对该类的四个属性进行打印。再定义一个Student类，该类继承Person类，并且额外新增一个marks的公有成员变量，也对Student类定义一个showinfor（）的方法对该类的四个属性进行打印。

这是一个计算机编程问题，我可以回答。以下是Python代码实现：

class Person:
    def __init__(self, name, age, sex):
        self.name = name
        self.age = age
        self.sex = sex
        
    def showinfor(self):
        print(f"Name: {self.name}, Age: {self.age}, Sex: {self.sex}")
        
class Teacher(Person):
    def __init__(self, name, age, sex, department):
        super().__init__(name, age, sex)
        self.department = department
        
    def showinfor(self):
        print(f"Name: {self.name}, Age: {self.age}, Sex: {self.sex}, Department: {self.department}")

class Student(Person):
    def __init__(self, name, age, sex, marks):
        super().__init__(name, age, sex)
        self.marks = marks
        
    def showinfor(self):
        print(f"Name: {self.name}, Age: {self.age}, Sex: {self.sex}, Marks: {self.marks}")

可以使用以下代码测试：

person1 = Person("Alice", 20, "Female")
person1.showinfor()

teacher1 = Teacher("Bob", 30, "Male", "Computer Science")
teacher1.showinfor()

student1 = Student("Charlie", 18, "Male", 90)
student1.showinfor()

输出结果：

Name: Alice, Age: 20, Sex: Female
Name: Bob, Age: 30, Sex: Male, Department: Computer Science
Name: Charlie, Age: 18, Sex: Male, Marks: 90
