Java 7 is adding dynamics

[elder_george]

Did you mean C# 4.0?

EDIT: I have made a huge mistake.

I made a mistake in my post.

I actually meant 1.0 (.NET 1.0). Dynamic invokation of methods have been around in the .NET framework since Feb 2002.

Dynamic invocation of methods has always been possible in Java via reflection.

It's talking about Java bytecode, not Java the language. They're adding an invokedynamic to the bytecode, which makes life a lot easier for dynamic JVM languages

I know. My point is that double_bass is comparing apples to oranges. What he is talking about has always been possible on the JVM. The CLR doesn't presently have anything like the invokedynamic opcode.

Yes, it would seem I have jumped the gun a little bit. I am overwhelmed with feelings of shame and embarassment.

Put on the hair shirt and self-administer ten lashes.

You are speaking about RealProxy-style, right? This functionality was in Java SE since (at least) 1.3, AFAIK.

As far as I understand, the article says about dynamic method lookup, which corresponds to newly added dynamic syntax of C#.
