Difference between method chaining and fluent interface

I wanted to know the exact difference between method chaining and fluent interface. As I understand it, method chaining is just running the methods of previous method return objects while avoiding temporary variables. An example of this could be Integer.parseInt(str).intValue()?

With respect to fluent interface, each method of the object is chained by a point, without having to be related to the previous method The two techniques make modifiers methods return to host objects, so that multiple modifiers can be invoked in a single expression like this:

 

new Car().StartsEngine().OpenWindow()

is this correct?
