A work queue coordinates the relationship between the producer and the consumer. When a new object is added to the queue, the message is sent to the consumer until the next message arrives in empty.

Scenario 1: Add Files (single, multiple, directory) to the GIT repository and submit a version snapshot.Scenario 2: Traversing history back to the past, version fallback, fallback from the current version to a previously submitted version.Application Scenario 3: Through history, version back more, the purpose of the time is 2000, the result was simply worn for 1900 years, no way, and from 1900 through to the "future" of 2000 years.Scenario 1:Suppose there is a directory work, inside three files:
number of core threads, create a new thread to run the task.
2. If the work queue is not full, put it in the work queue
3. If the work queue is full (PS: workQueue. offer (command) returns false), a new thread is created.
4. If the number of threads has reached the maximum number of threads, reject (command)
In the previous execute method, the addWork () method is called in three places.
First, if the number of valid threads is less than the number
