下推字段

open in web edition

如何访问网络版？

refactorgram

class Employee {        // Java
  private String quota;
}

class Engineer extends Employee {...}
class Salesman extends Employee {...}

image/svg+xml 

class Employee {...}
class Engineer extends Employee {...}

class Salesman extends Employee {
  protected String quota;
}

是 上拉字段 的反面
