I strongly prefer how interfaces are handled

It's better than Java, but they still chose to walk headfirst into the same trap that bites Java developers in the ass: associating interface implementations with the struct/class rather than the interface itself.

When you have two interfaces that each require you to implement a function with the same name but a different signature, you're in for a bad time featuring an abomination of wrapper types.

Edit: Clarity.

On that last note, can't you use the explicit interface implementation in C#?

e.g.

public class SampleClass : IControl, ISurface
{
    void IControl.Paint()
    {
        System.Console.WriteLine("IControl.Paint");
    }
    void ISurface.Paint()
    {
        System.Console.WriteLine("ISurface.Paint");
    }
}

Edit: I misread your comment as "like in C#" and wrote this as an answer to the non-existent question of "can't you use explicit interfaces like in C#"

I haven't kept up with recent Java developments, but with Go, you're out of luck. Interface implementations are completely implicit. You don't even have an implements keyword.

Edit: For Java, a cursory search suggests that they haven't yet added explicit interfaces: https://stackoverflow.com/questions/19111090/does-java-support-explicit-interface-implementation-like-c

He mentioned C#, which does let you explicitly choose to implement same-name functions of two interfaces with different code

For some reason, my brain inserted a "like" before "in C#", and answered the question of "can't you use explicit interfaces like in C#."

just one more oop bro I swear

Pure oopium. All oop 'design patterns' exist solely to overcome the inherent flaws of oop.

Didn't understand my criticisms of Go and Java's interfaces, or do you just enjoy LARPing as a senior programmer while living in a small world where the term "interface" strictly means object-oriented programming and not the broader idea of being a specification describing how systems can interact with each other?
