Green threads are created and scheduled by Virtual machine without using OS libraries. 

“Green” was the project code name of the thread project which was developed by the Java, therefore the name of the thread is “Green”. It can not make use of multiprocessor.

On the other hand, Native threads are created and scheduled by Kernel of operating system. It can swap between threads from running thread to non-running thread. All modern OS supports native thread.
