**定义一个Person类，含姓名、性别、年龄、年龄等字段；继承Person类设计Teacher类，增加职称、部门等字段；继承Person类设计Student类，增加学号、入学时间、专业等字段。定义各类的构造方法和toString()方法，并分别创建对象进行测试。**

public class Persons {
        
        public static void main(String[] args) {
        
            Teacher A = new Teacher("张三", "男", 35, "教授", "教学");
            Student B = new Student("李四", "男", 20, 123, 201809, "computer");
            System.out.println(A.toString());
            System.out.println(B.toString());
        }
    }
    
    class Person {
        
        private String name;
        private String sex;
        private int age;
    
        public String getName() {
        
            return name;
        }
    
        public void setName(String name) {
        
            this.name = name;
        }

            return age;
