1、编写一个类Test01.java，实现以下内容： 1）设计两个类Student1（属性：学号）和Teacher（属性：工号，方法：教学） 2）抽取两个类共同的内容（如：属性-姓名、性别，方法：吃饭、睡觉）封装到一个类Person中，各自特有的部分保留在各自类中。 3）让学生类继承Person类，老师类也继承Person。 4）实现测试类Test01，测试Student1类和Teacher是否继承了Person类的成员。

代码如下：

Person类：

public class Person {
    private String name;
    private String gender;
    
    public void eat() {
        System.out.println("I am eating.");
    }
    
    public void sleep() {
        System.out.println("I am sleeping.");
    }
    
    // getter and setter methods
}

Student1类：

public class Student1 extends Person {
    private String studentId;
    
    // getter and setter methods
}

Teacher类：

public class Teacher extends Person {
    private String teacherId;
    
    public void teach() {
        System.out.println("I am teaching.");
    }
    
    // getter and setter methods
}

Test01类：

public class Test01 {
    public static void main(String[] args) {
        Student1 student = new Student1();
        teacher.setName("Alice");
        teacher.setGender("Female");
        teacher.setStudentId("20190001");
        System.out.println(student.getName()); // should print "Alice"
        System.out.println(student.getGender()); // should print "Female"
        student.eat(); // should print "I am eating."
        student.sleep(); // should print "I am sleeping."
        
        Teacher teacher = new Teacher();
        teacher.setName("Bob");
        teacher.setGender("Male");
        teacher.setTeacherId("10001");
        System.out.println(teacher.getName()); // should print "Bob"
        System.out.println(teacher.getGender()); // should print "Male"
        teacher.eat(); // should print "I am eating."
        teacher.sleep(); // should print "I am sleeping."
        teacher.teach(); // should print "I am teaching."
    }
}

在测试类中，我们创建了一个Student1对象和一个Teacher对象，并分别调用它们从Person类继承的方法和属性，以及它们自身特有的方法和属性。如果一切正常，输出结果应该符合上面的注释。
