Hi Folks ,

I was going through Object pool design pattern...

Implementation involves the following objects:
Reusable - Wraps the limited resource, will be shared by several clients for a limited amount of time.
Client - uses an instance of type Reusable.
ReusablePool - manage the reusable objects for use by Clients, creating and managing a pool of objects.

When a client asks for a Reusable object, the pool performs the following actions:
- Search for an available Reusable object and if it was found it will be returned to the client.
- If no Reusable object was found then it tries to create a new one. If this actions succeds the new Reusable object will be returned to the client.
- If the pool was unable to create a new Reusable, the pool will wait until a reusable object will be released

Please advise how this pattern would be implemented in java, through executor framework , please advise..!!

Why do you have to use an executor?

Have you tried implementing it yourself? What have you tried until now?

If you are just looking to study and existing implementation, google for Apache Object Pool. Apache has a good open source implementation of an object pool. You can download the source and study it.
