Problem in Creation of reference to the Interface

Hi Friends,

Pls help me. Actually i have a common dout. In API we have lot of Interfaces like FileInput, DataBaseMetaData. In few cases i know that i can use the function in the predefined interfaces but i dont know the method which return the references to the Interfaces or the class which implements that interfaces.

Eg., ObjectInput obj=new ObjectInputStream();

I'm using Java API for my references but is there any other method or else whether it can be checked in Java API itself

Thanks in Advance,

Murali
