This wiki will explore how reflection is implemented with both Ruby and Java, with the goal of showing which language's implementation makes it easier to write, easier to understand, and more efficient.

Basics

Reflection in Java

<context> class MountainBike { boolean diskBrakes() { return true; } boolean knobbyTires() { return true; }

public static void main (String argv[]) { Class c = MountainBike.class; Method methods[] = c.getDeclaredMethods(); for (int i=0; i<methods.length; i++) { System.out.println(methods[i].getName()); } } } </context>
