Is calling super's constructor redundant in this case? [duplicate]

由 廉价感情. 提交于 2021-01-29 18:14:27
问题 This question already has answers here : Is it unnecessary to put super() in constructor? (6 answers) Closed 6 years ago . I always thought that when creating an object with a sub-class, we need to explicitly use super(arguments list) to call the constructor of the super class. However I did an experiment and realize that even without using the super() , the super class's constructor will be called automatically. Is this true? If this is true, when is super() redundant and when it is not?

SUP Personalization Key via Native Android Search button

由 北战南征 提交于 2019-12-25 03:42:52
问题 I'm setting up a simple demo of SUP on android natively but I'm having a few doubts regarding how to use personalization keys. Using the SUP101 sample as a basis (here), I've created a 'state_pk' personalization key to filter customers by state. I'd like to be able to get this data by using the "search button" from Android (which I already have setup and showing correctly). I've also added a findByState object query to the customer MBO to be able to filter, but to my (little) understanding

relative font-size of <sub> or <sup> and their descendants in IE

由 六月ゝ 毕业季﹏ 提交于 2019-11-28 11:15:39
Trying the " Eric Meyer Reset " I stumbled across an issue concerning the font-size:100% declaration to reset the font size of all suitable elements. font-size:100% means the elements should inherit font-size property of their parent, but this is not the case with the <sub> and <sup> elements and their descendants in IE (tested in 6,7,8 and 9th version). For example (or this live example on a playground ): // CSS: sup,span {font-size:100%;} // HTML: if you try this in IE, <sup>this text will be smaller <span>and this even more</span></sup> It seems like just another implementation trick, that
