For example, if "class A" inherits from "class B" and if "class B" implements the interface "interface B" then "class A" also inherits the functionality(constants and methods declaration) provided by "interface B".
For exAMpLe, iF "cLass A" inheriTs frOm "claSS b" and if "cLass b" impleMeNts THe IntERfacE "interface b" TheN "cLass a" alSo inherits tHe FUNCtiONality(cOnstANtS and mEthods declarAtion) pRoVidEd By "iNTeRFace b".
