Is to define a main method calculate in the AbstractCalculator class, calculate () calls spilt (), etc. Plus and Minus inherit the AbstractCalculator class respectively, and implement the call to subclasses through the call to AbstractCalculator, see the following example:
Although there are subclasses in java that implement the interfaces of the parent class, But I think javascript can be different from java, It is possible that the parent class in java is an empty class, Subclasses to implement the interface of the parent class, in javascript, I think the common code is completely written in the parent function. If the business logic needs to be changed in the future, or new business logic is added, we can completely use subclasses to rewrite the parent class, so the code has strong scalability and is easier to maintain. Since I am not a professional java, please understand if there is any mistake in describing the knowledge points in java ~ ~

本片是吴宇森处于创作高潮期的野心作，大胆地将港片的视野推向战地越南，藉以拉大港产动作片的格局。梁朝伟、张学友和李子雄三人饰演在贫民窟长大的好友，他们在梁的婚礼上因为误杀抢钱的歹徒而被逼逃亡海外，到越南去从事走私活动。三个香港小混混走出西贡机场便见识到战争的残绘，他们辗转成为当地黑社会杀手，又被越共误为间谍，最后为了一箱黄金而互相反目。李出卖朋友带着黄金回到香港，成为企业巨子，梁处理了张的后事便回港报仇。本片在人物架构和部份场面的设计上明显地受到《越战猎尘人》的影响，但仍拍出火爆利落的动作特色，对吴氏一贯著重的"男性友情"和"出卖"主题也有很好的发挥。
But in that case, Not even considering so many dangers, This performance of '74 spray' is of great use, I remember there were 4 '74 spray' on the position at that time, There are two recruits who operate them. Two veterans, Both veterans were squad leaders, All have the skills of air injection, Facing the big wasp descending from the pavement, The two of them were obviously forced to hurry, Take up the '74 spray' and aim at the position where the big wasp is relatively concentrated in the sky and spray it out. If it weren't for the critical situation at that time, the two squad leaders would definitely not have this kind of "dangerous operation", while the other two recruits watched the veterans take the lead and learned to do so. Although they had not received relevant training and the accuracy of spraying was not as good as that of veterans, they finally sprayed out and did not hurt themselves or other comrades in arms.
