Parameterized Types for Java 来自 ResearchGate 喜欢 0 阅读量: 25 作者:AC Myers,JA Bank 摘要: Introduction Java [8] promises to be an important language for WWW applications and software development in general. This popularity arises from several factors: simple object-oriented design; syntactic ...
(see /PRO1/). This time we aim to explain wildcards – another language construct relevant in the context of Java Generics. Wildcards can be used for instantiation of parameterized types. In its simplest form a wildcard is a question mark “?” and permits type declarations such as List<...
Well, the kinds of instantiations we’ve seen so far where we plug in an actual Java type as a parameter are called concrete type instantiations. Later we’ll talk about wildcard instantiations, which are akin to mathematical set operations on types. We’ll see that it’s possible to make...
