When should we use Java's Thread over Executor?

Question

Executor seems like a clean abstraction. When would you want to use Thread directly rather than rely on the more robust executor?

Answer 1

To give some history, Executors were only added as part of the java standard in Java 1.5. So in some ways Executors can be seen as a new better abstraction for dealing with Runnable tasks.

A bit of an over-simplification coming... - Executors are threads done right so use them in preference.
