# Fruit of the Loom: Exploring Project Loom and Virtual Threads
## Examples
### Non-Blocking
This example shows what happens when you execute a `Runnable` which doesn't perform a blocking operation in a `VirtualThread`.
```shell
mvn -Pnon-blocking compile exec:java
```
You should see output similar to the following:
```shell
