}
public static void main(String args[])
{
Person a=new Person("男","张三","18");
System.out.println(a.toString());
Teacher b=new Teacher ("女","李四","33","教授","计算机学院");
System.out.println(b.toString());
Student c=new Student ("女","王五","22","123","2021.9.1","计算机");
System.out.println(c.toString());
}
}
}
怎么修改不报错Teacher b=new Teacher ("女","李四","33","教授","计算机学院");

}
修改Teacher b=new Teacher ("女","李四","33","教授","计算机学院")，可以改为：
Teacher b = new Teacher("女", "李四", "33", "教授", "计算机学院");
