I'm new to java, and this question struck me. When you instantiate an object, why do you specify the class twice? OddEven number = new OddEven(); Why can't you just say number = new OddEven();? When I delcare a string, I only say String once: String str = "abc"; Actually, my question is not "why do you do it this way" -- obviously...

I just wondered whether there is any good reason for or even an advantage in having to invoke Procs using proc.call(args) in Ruby, which makes higher-order function syntax much more verbose and less intuitive. Why not just proc(args)? Why draw a distinction between functions, lambdas and blocks? Basically, it's all the same thing so why...
I have a small Ruby script where an array is initialized to hold a few strings MyArray = ["string 1", "string 2" , "string 2" ] The problem is that I have quite a few strings in the initialization list and I would like to break the line: MyArray = [ "string 1" ,"string 2" ,"string 2" ] ...
I occasionally run into this type of syntax when looking through open source code and was wondering what it's for, or what it's even called for that matter.

[totalSeconds:9 minutes:59 seconds:59] Is this kind of syntax acceptable: -...

Hi, I'm curious to know what the syntax " : " mean in php I've seen it a couple of times but I can't seem to explain it to myself.
