java - List of Lists of Lists

I'm new to Java and I need to make a list of lists of lists. I could do it in python because an element of a list can be a list so in an embedded list list[0] would refer to a list and list[0][0] would refer to the zeroeth element of the embedded list. Is there any easy way to implement this behavior in java?

All the other answers are technically correct, but IMHO if you implement a rough List of Lists of Lists you are not treating your data at the right level of abstraction. For example I am pretty sure that a List of Lists already means "something" in your business domain. Encapsulate this "something" in another object so you can just have a List<Something> instead of a difficult to use and maintain List<List<List<Object>>>.
