With the Java Reflection API, we can isolate the abstract methods from a class via the following snippet of code:
List abstractMethods = new ArrayList();
Class clazz = Foo.class;
Method[] methods = clazz.getDeclaredMethods();
for (Method method : methods) {
if (Modifier.isAbstract(method.getModifiers())) {
abstractMethods.add(method);
}
}
