        student.className = "一班";
        student.hobby = "打游戏";

        student.show();
    }
}

class Student{
//    定义相关的属性 姓名  爱好 班级  年龄
    String name;

    String className;
    String hobby;

//    定义相关的行为，打印学生信息
    public void show(){
        System.out.println("Student{" + "name='" + name + '\'' + ", age=" + age + ", className='" + className + '\'' + ", hobby='" + hobby + '\'' + '}');

    }

}

        teacher.major  = "计算机";
        teacher.course = "课程呢个";

        teacher.show();
    }
}

class Teacher{
//    姓名
    String name;
//    专业
    String major;
//    课程
    String course;
//    教龄

                ", course='" + course + '\'' +
                ", teacherAge='" + teacherAge + '\'' +
                '}');
    }
}
定义一个管理类
定义一个管理员类Adminisistrator
定义其相关的属性和方法
定义一个测试类TestAdministrator
创建两个管理员的类对象，并输出他们的信息

public class Adminisistrator {

    String username;
    String password;


    /**
     * 判断账号密码是否正确
     * @return
     */
    public boolean login(){
        System.out.println("登录账号");
        if ("root".equals(username) && "root".equals(password)){
            return true;
        }
        return false;
    }

    public void logout(){
        System.out.println("推出登录");
    }
}

public class TestAdminisistrator {
    public static void main(String[] args) {
        Adminisistrator adminisistrator = new Adminisistrator();
        adminisistrator.username = "root";
        adminisistrator.password = "root";
        adminisistrator.login();
        System.out.println(adminisistrator.toString());

        Adminisistrator adminisistrator2 = new Adminisistrator();
        adminisistrator2.username = "qwe";
        adminisistrator2.password = "213";
        adminisistrator.login();
        System.out.println(adminisistrator2.toString());

    }
}
