The ThreadFactory interface has only one method, called newThread(). It receives a Runnable object as a parameter and returns a Thread object. When you implement a ThreadFactory interface, you have to implement it and override the newThread method. The most basic ThreadFactory has only one line:
return new Thread(r);
You can improve this implementation by adding some variants, as follows:
- Creating personalized threads, as in the example, using a special format for the name or even creating your own Thread class that would inherit the Java Thread class
- Saving thread creation statistics, as shown in the previous example
- Limiting the number of threads created
- Validating the creation of the threads
