Greetings, Java seems to be almost a subset of D in various ways. Has there been any work done to automatically translate Java source into D?

Java is more powerful than D as for a language. Many things that Java can do can't be done by D. For example, reflection, full meta info for a type in runtime, type deduction for a template, template member override.

The fact is that there are many stuff waiting for you to implement them when you are porting a project from Java to D, like the different or missing APIs, language features etc. See what we got from the portings: Containers: https://github.com/huntlabs/hunt/tree/master/source/hunt/collection Threading: https://github.com/huntlabs/hunt/tree/master/source/hunt/concurrencyOn Thursday, 14 November 2019 at 19:50:22 UTC, NonNull wrote:With the compile time reflection capabilities of D you can build a runtime reflection system.

Pls I need more clarity on this by professional in this group. I am of the opinion that D is much more powerful than Java since I am familiar with the language to some extent. I am even to start a GUI app in java due to the fact I have no find a GUI toolkit in D that meet all my need.

Generics in java are mainly compile time thing that boils down to auto generated casts when working with generic types (in bytecode), and therefore a templated method in java is actually a standard method that just works with Object class under the hood, hence it is possible to override in implementor of interface/class. It can be done in D too you'll just need to strip out generics part in method declaration and just use casts from root Object for worst case. Also what do you mean by "type deduction for a template"?
