Many poeple don't know this trick! Actually, I just found it today! It works like a dream! Just check this example out:

public static void main(String[] args) throws NoSuchMethodException {
    Date d=new Date();  //Or anything you want!
    printMethods(i);
}

public static  void printMethods(T t){
    Class clazz= (Class) t.getClass(); // There you go!
    for ( Method m : clazz.getMethods()){
        System.out.println( m.getName() );
    }
}
