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。 类的一个很好的用途是作为泛型类型(包括Collection类,比如list...
Approaches that "intern" boxed primitive objects to a canonical memory location are too heavyweight。区分 identity 类和接口继承图(根为 Object)与原始类和接口继承树(根为一个新的类或接口)的方式阻止了与现有 Java 代码的互操作性。 C-like 语言中支持对 strcut 或者其他类似类的抽象扁平化存储。例如,C#...

Unity can work with 3D models of any shape that can be created with modelling software. However, there are also a number of primitive object types that can be created directly within Unity, namely theCube,Sphere,Capsule,Cylinder,PlaneandQuad. These objects are often useful in their own right...

Although the concept of casting is reasonably simple, the usage is complicated by the fact that Java has both primitive types (such as int, float, and boolean) and object types (String, Point, ZipFile, and the like). There are three forms of casts and conversions to talk about in this...
