Concurrent computing

Concurrent computing
You are encouraged to solve this task according to the task description, using any language you may know.

Using either native language concurrency syntax or freely available libraries write a program to display the strings "Enjoy" "Rosetta" "Code", one string per line, in random order. Concurrency syntax must use threads, tasks, co-routines, or whatever concurrency is called in your language.
