How to execute tasks in ExecutorService sequentially?

Question

I have three threads that are joined, i.e. the second thread executes after the first dies.

This is the code I have:

public class Main {
    public s

If you already use a thread pool in your application, you can reuse it by means of zero-threaded proxy serial executor, without creating special single threaded thread pool. One implementation is described in the javadoc section of Executor interface, another, optimized implementation, at my Github repository CodeSamples.
