Declaring a LinkedList in Java

Question

I always learn when we declare a collection we should do, Interface ob = new Class(), if i want to use for example a LinkedList i\'ll do List ob = new LinkedL

Answer 1

You should always try to keep the declaration at the highest level possible, meaning that you should stop at the highest level that provides all the functionality that you need: if List methods are not enough, you're perfectly fine with your LinkedList declaration.
