New JEP Would Simplify Java Type Variance

by Abraham Marín Pérez Follow 9 Followers on  Jan 24, 2017

A new JEP Candidate proposes to facilitate the handling of type variance in Java. The new proposal, potentially targeting Java 10, would add a means for specifying the default variance in the definition of generic types, different to the current style of indicating it through wildcards at instantiation. This proposal is not a replacement for wildcards, but rather a way to reduce the need for them.

Java Enums to Be Enhanced with Sharper Type Support

by Abraham Marín Pérez Follow 9 Followers on  Jan 10, 2017 5

Java enums will be enhanced with generics support and with the ability to add methods to individual items, a new JEP shows. Since both features can be delivered with the same code change, they are bundled together in the same JEP. The change only affects the Java compiler, and therefore no runtime changes are needed. Although there is no target version, Java 10 seems likely.


Richard Warburton and Raoul-Gabriel Urma Review the History of Generics in Java at Devoxx UK

by Abraham Marín Pérez Follow 9 Followers on  Jul 01, 2015

Richard and Raoul, who provide in person training courses on Java 8, offered a joint presentation at Devoxx UK 2015 where they discussed the origins and motivations for Generics in Java, some of the less known current features, and a glimpse of what might be coming up in Java 10. The presentation was split into three distinctive sections: past, present and future of Generics.

by Sergio De Simone Follow 21 Followers on  Aug 23, 2014 2

C++14, the new C++ standard succeeding C++11, has been finally approved and is heading to ISO for publication this year. While improvements in C++14 are "deliberately tiny" compared to C++11, says C++ creator Bjarne Stroustrup, they still "add significant convenience for users" and are a step on the route to make C++ "more novice friendly."

Covariance and Contravariance in .NET Generics

by Jonathan Allen Follow 655 Followers on  Aug 13, 2008

Currently .NET languages such as VB and C# do not support covariance and contravariance for generics. While this is not likely to chance in the near future, people at Microsoft are talking about it.


Two years later, frustration with Generics continues

by Rob Thornton Follow 0 Followers on  Nov 02, 2006 8

Laird Nelson describes his frustrations with understanding Java Generics. While clear in the simple case, as he works through a more complicated scenario, he ends up throwing them away because they're so complicated. Are we helping or hurting ourselves by using Generics?
