用java设计一个名为person的类和它的两个子类名为Student和Employee的子类，Employee的子类又有子类教员类Faculty和职员类Staff。每个人都有姓名、地址、电话号码、和电子邮件地址。学生有班级状态（大一）

好的，以下是Java代码实现：

public class Person {
    private String name;
    private String address;
    private String phoneNumber;
    private String email;

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

    // Getters and Setters
    // ...

    @Override
    public String toString() {
        return "Name: " + name + "\nAddress: " + address + "\nPhone number: " + phoneNumber + "\nEmail: " + email;
    }
}

public class Student extends Person {
    private String gradeStatus;

    public Student(String name, String address, String phoneNumber, String email, String gradeStatus) {
        super(name, address, phoneNumber, email);
        this.gradeStatus = gradeStatus;
    }

    // Getters and Setters
    // ...

    @Override
    public String toString() {
        return super.toString() + "\nGrade status: " + gradeStatus;
    }
}

public class Employee extends Person {
    public Employee(String name, String address, String phoneNumber, String email) {
        super(name, address, phoneNumber, email);
    }

    // Getters and Setters
    // ...
}

public class Faculty extends Employee {
    public Faculty(String name, String address, String phoneNumber, String email) {
        super(name, address, phoneNumber, email);
    }

    // Getters and Setters
    // ...
}

public class Staff extends Employee {
    public Staff(String name, String address, String phoneNumber, String email) {
        super(name, address, phoneNumber, email);
    }

    // Getters and Setters
    // ...
}

以上就是一个名为`Person`的基类和三个子类`Student`、`Employee`和`Faculty`的Java实现。

其中，`Student`类有一个额外的属性`gradeStatus`，表示学生的班级状态。而`Employee`类没有额外的属性，它的两个子类`Faculty`和`Staff`都没有额外的属性，只是继承了基类`Person`的属性。这里只给出了类的定义和属性，需要根据具体的需求添加方法等。
