T - The Java Generic of type "T" is explicitly defined at compile-time.

MethodBlockingTask blocks retrieve() until the execute()
method has fully completed and terminated.printThreadIdFlag| Modifier | Constructor and Description |

The execute() method allows clients to execute the business logic associated

From the parent document:
Returns the value of the obj in a ThreadSafe manner. The method blocks until a condition is
met (such as the excute() method returning or the obj of type <T> being set (via the setVal()
method). For more information on the way internal contention is handled, please refer to
MethodBlockingTask and ObjectBlockingTask.
