I wanted to know that, is it possible to create a pool of objects? So that I can take an object from the pool and once I'm done with the work, I can put it into the pool.

It is possible yes. You can see performance improvements in many situations if the construction of a new object is expensive (like establishing a database connection) or if for other reasons the GC bandwidth is too high (often a problem in Android-land).
Here are some resources that you could use to implement your pool. You may be able to use Apache's ObjectPool right out of the box.
- Apache Commons ObjectPool
- Does this basic Java object pool work?
- Build your own ObjectPool in Java to boost app speed
- Object Pool Design Pattern in Java
- Google search: java object pool
