POJI

"A Java Interface Which does not extends from any Technology Specific Interfaces is Called POJI".

Eg:                                                                                                          

public interface I {                   public interface J extends I{
//Method Declaration.                    //Method Declaration.                    
}                                                     }
Here interface I and J are POJIs.

public interface k extends java.rmi.Remote{
//Method Declaration.                    
}                                          
Here K is not POJI Because 'Remote' is a part of rmi Technology.
