java创建一个老师和学生都可以收取作业的接口类的测试类

好的，以下是一个简单的 Java 接口类及其测试类的实现，供您参考：

// HomeworkReceiver 接口类
public interface HomeworkReceiver {
    void receiveHomework(Homework homework);
}

// Student 类实现 HomeworkReceiver 接口
public class Student implements HomeworkReceiver {
    private String name;
    
    public Student(String name) {
        this.name = name;
    }
    
    @Override
    public void receiveHomework(Homework homework) {
        System.out.println(name + " received homework: " + homework.getDescription());
    }
}

// Teacher 类实现 HomeworkReceiver 接口
public class Teacher implements HomeworkReceiver {
    private String name;
    
    public Teacher(String name) {
        this.name = name;
    }
    
    @Override
    public void receiveHomework(Homework homework) {
        System.out.println(name + " received homework: " + homework.getDescription());
    }
}

// Homework 类
public class Homework {
    private String description;
    
    public Homework(String description) {
        this.description = description;
    }
    
    public String getDescription() {
        return description;
    }
}

// Test 类
public class TestHomeworkReceiver {
    public static void main(String[] args) {
        // 创建一个学生和一个老师
        Student student = new Student("Tom");
        Teacher teacher = new Teacher("Lucy");
        
        // 创建一个作业
        Homework homework = new Homework("Java 接口类");
        
        // 学生和老师都可以收取作业
        student.receiveHomework(homework);
        teacher.receiveHomework(homework);
    }
}

在上面的代码中，我们定义了一个 `HomeworkReceiver` 接口类，其中有一个 `receiveHomework` 方法，用于接收作业。然后我们创建了一个 `Student` 和一个 `Teacher` 类，它们都实现了 `HomeworkReceiver` 接口，并实现了 `receiveHomework` 方法。最后我们创建了一个 `TestHomeworkReceiver` 测试类，用于测试我们的代码是否正确。在测试类中，我们创建了一个学生和一个老师，并创建了一个作业，然后分别让学生和老师收取作业。
