I need to implement Exception management component, in Java.

Having this class :

public class Foo {

   void connect(){
       // some instructions here...
   }

}

The specification document that I have uses such expressions :

1. A_Exception can be received.

2. B_Exception can be catched as C_Exception .

Edit : What is the difference between a caught exception and a received exception? Some sample codes would be so helpful.
