## Check the Virtual Environment is Active { #check-the-virtual-environment-is-active }

Check that the virtual environment is active (the previous command worked).

/// tip

This is **optional**, but it's a good way to **check** that everything is working as expected and you are using the virtual environment you intended.

### 8.2 Network Partition Handling
```java
public class WitnessNetworkPartitionHandler {

   * {@code join("-", 1.0f, 2.0f, 3.0f)} returns the string {@code "1.0-2.0-3.0"}.
   *
   * <p>Note that {@link Float#toString(float)} formats {@code float} differently in GWT. In the
   * previous example, it returns the string {@code "1-2-3"}.
   *
   * @param separator the text that should appear between consecutive values in the resulting string
   *     (but not at the start or end)
