例如,定制部件需要知道什么字符串作为名称。

<强 > 压倒

CustomComponent c = new CustomComponent(){
    @Override
    public String getTitle(){
        return "A given title";
    }
};

<强 > 字段

CustomComponent c = new CustomComponent()
c.setTitle("A given title");


Using the first 方法,我不需要在自定义元件中创建字符串字段,但代码要干净得多。是否有强烈偏好/建议的方法,如果有,为什么?
注意,这只是一个简单的例子。

谢谢 谢谢

最佳回答

如果所有“自定义元件”都有一个简单的字符串标题,则数据字段就是前进的方向。

一旦事情变得有点复杂(例如,标题需要子类特定信息[例如,它“拥有”多少个孩子]),就移到方法上。
