Get the Abstract Methods of a Class

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);
    }
}
