Implementing Generic Interface in Java -

i have java generics question hoping answer. consider following code:

public interface event{} public class addresschanged implements event{} public class addressdiscarded implements event{}  public interface handles<t extends event>{     public void handle(t event); } 

i want implement handles interface this:

public class addresshandler implements handles<addresschanged>, handles<addressdiscarded>{     public void handle(addresschanged e){}     public void handle(addressdiscarded e){} } 

but java doesn't allow implementing handles twice using generic. able accomplish c#, cannot figure workaround in java without using reflection or instanceof , casting.

is there way in java implement handles interface using both generic interfaces? or perhaps way write handles interface end result can accomplished?

you can't in java. can implement 1 concrete realization of same generic interface. instead:

public class addresshandler implements handles<event>{     public void handle(event e){       if(e instanceof addressdiscarded){          handlediscarded(e);       } else if(e instanceof addresschanged){          handlechanged(e);       }     }     public void handlediscarded(addressdiscarded e){}     public void handlechanged(addresschanged e){} }
