Well I wrote some code and all I was doing was for loops, but changing which method I called. I tried using a for loop so it'd be a bit neater (and out of curiosity to see if it could be done), but it doesn't compile when I do it this way, because it doesn't recognize an item in an array as a method, I think. This is what I have: String...

I have a simple question: what's the advantage of instantiating a C# delegate as opposed to just passing the function reference? What I mean is: Why do: Thread t = new Thread(new ThreadStart(SomeObject.SomeMethod)); When you can do: Thread t = new Thread(SomeObject.SomeMethod); Both will compile and work in my experience...am I m...
Generics bring in a lot of goodness to java but they also mean trouble because of the introduction of bridge methods which mean its not easy to locate a method given a name and target because erasure and bridge methods mean clients actually use the bridge rather than the target. Return types from methods have been omitted because they a...
Hello, I am trying to invoke a method via reflection with parameters and I get "object does not match target type". If I invoke a method without parameters it works fine.

Why can't Java classes have abstract fields like they can have abstract methods? For example: I have two classes that extend the same abstract base class. These two classes each have a method that is identical except for a String constant, which happens to be an error message, within them. If fields could be abstract, I could make thi...

I've inherited a large pile of Ruby code that's, frankly, close to impossible to understand for a mortal like myself. It's actually Rspec unit test code, but the structure is "highly unusual" to put it nicely. What I'd like to be able to do is run the code, and have the following information logged somewhere: every method that gets i...
