Java 中的实体和模型应该使用 Primitive 还是 Object ?Max*_*ell 2 java primitive 作为Java 的初学者,我在选择实体或模型类中的变量类型时感到困惑。正如在Java Primitives vs Objects 中提到的,它们都有一些优点和缺点,例如内存使用。但是,我想知道创建实体或模型类时的一般方法。那么,在这种情况下,对于 long、...
DTO (Data Transfer Object):DTO是一种设计模式,用于在应用程序的各个层之间传输数据。它通常包含多个属性,用于封装数据,并且可以在不同的层之间传递。 Primitive:在编程中,原始数据类型(如int, double, boolean等)是最基本的数据类型,它们不是对象,不能包含其他数据。 优势 DTO的优势: 封装性:DTO可以封装多个相关...

Object obj = (java.lang.Integer)i; But in J# you can do the following: int i = 0; Object obj = (System.Int32)i; Q> It sounds like the existence of @ref makes the use of Integer and the same useful just for maintaining Java compatibility (if someone really ne...
utils.ObjectMap,com.badlogic.gdx.utils.OrderedSet, andcom.badlogic.gdx.utils.OrderedMap. As nice as it would be to just call these by the same names (except Array and Queue, those are just confusing), we have other kinds of Object-keyed Maps, and other kinds of insertion-ordered Maps,...
在Effective Java 的第五项中, Joshua Bloch 有这样的观点: The lesson is clear:prefer primitives to boxed primitives, and watch out for unintentional autoboxing. 意思就是:相对于boxed primitive更喜欢primitive,并且需要注意无意识的autoboxing机制。
