java - Overloading methods in an interface using generics as parameters -

i have java interface defining method takes interface b parameter. want know if possible overload method in implementing class give parameter object implements interface b. here's sample code of mean:

public interface sampleinterfacea{     public void samplemethod(sampleinterfaceb b); }  public class classb implements sampleinterfaceb{} public class classc implements sampleinterfaceb{}  public class sampleclassa implements sampleinterfacea{     @override     public void samplemethod(classb b){} }  public class sampleclassb implements sampleinterfacea{     @override     public void samplemethod(classc c){} } 

thanks in advance help.

if try it, you'll see sampleclassa , sampleclassb seen compiler missing needed implement sampleinterfacea.

you need implement actual method defined in interface.

a way approximately seem want use generics:

public interface sampleinterfacea <t extends sampleinterfaceb>{     public void samplemethod(t b); }  public class sampleclassa implements sampleinterfacea<classb>{     public void samplemethod(classb b){} }  public class sampleclassb implements sampleinterfacea<classc>{     public void samplemethod(classc c){} }
