Very true, in Java, at least in the last 20 years, inheritance is de-facto deprecated, all new bits and bolts like enums, annotations, lambdas or records do not support inheritance. So you have to use composition.

COBOL changes very slowly, once in a decade or two. Python does not offer support of a release for more than 3 years and a half [1]. [1] https://en.wikipedia.org/wiki/History_of_Python

This is similar to the expression tree API of C# so no change in the JVM is required, only cooperation between the java compiler and the reflection API. The code model can be computed by the compiler, inserted in the classfile in a specific

Yes, it's functions vs methods. You can make this explicit like in Python, you can make it implicit but have two kinds of methods, instance methods and static methods like in C++/C#/Java. And you have JavaScript were all func

Even if I think that Guy Steele is a genius, an argument of authority is always a bad argument. Better listening to the foot soldiers than staying in your high tower. Using '\' instead of '$' does not allow $variable as

Sadly escape analysis in Java is weak. In this case, it only works if all the template values do not escape.

Yes, you do not get a compile time error, but visually a big STR is front is enough "${variable}" vs STR."${variable}" And editors will use different colors. Using \ or $ is not about backward compatibility but about e

by _old_dude_ 3y ago
You can not use the excuse of the backward compatibility twice. If the string template is prefixed by a processor STR."foo" instead of "foo" then you do not need \{variable} instead of $variable.
46.
by _old_dude_ 3y ago
Both the syntax and the semantics are awful. They are overthinking it. Processor should not require to allocate a list of objects do to string templating. Only STR and FMT get good perf because they are specialized by the compiler.

You still need virtual dispatch (or type pattern matching) if there is a variable which can contain either a BDRepo or a LoggedRepo(BDRepo).

Developers should understand if a dependency use C bindings. But why bother end users with a command line flag. Perhaps there is a manifest entry/flag so the command line flag is not required ?

You have two kind of concurrent GCs, the ones where the marking phase in concurrent with the application and the ones where the evacuation phase is also concurrent with the application. G1 only does the marking concurrently, the evacuation

I remember James Gosling saying, a long time ago, that the whole class should be either mutable or not so you do not need to tag some methods with const. The consequence is that you may define two classes, one non-mutable and one mutable li

It's not generational GC, it's generational ZGC. ZGC is a concurrent GC, both the marking phase and the evacuation phase are done concurrently with the program running. A generational ZGC is a generational concurrent GC. MS does n

It's prefixed by "STR." so the syntax is different from any existing tools ? It remember me the first proposed syntax for lambdas. Let's hope the next preview will fix that.

In C#, value types and reference types are two separate kind of types, value types are pass by copy (like C structs) and generics where clauses have coloring (struct constraints [1]). In Java, value types are immutable so the VM can pass by

Closing the hierarchy or not depend on the use cases, for an application most hierarchies are closed. For a library most are open. For example, if your application receive JSON objects, you know all of them so, it's a closed hierarchy.

by _old_dude_ 3y ago
It depends if the hierarchy is open or closed. If the hierarchy is open, the behavior is defined in each subtypes and it's easy to add a new subtypes but you can not add a new operation (a new method). That's the OOP way. If the h
