== Why is this an issue?

All classes extend ``++Object++`` implicitly. Doing so explicitly is redundant.


Further, declaring the implementation of an interface _and_ one if its parents is also redundant. If you implement the interface, you also implicitly implement its parents and there's no need to do so explicitly.

=== Noncompliant code example

[source,java]
----
public interface MyFace {
  // ...
}

public interface MyOtherFace extends MyFace {
  // ...
}

public class Foo 
    extends Object // Noncompliant
    implements MyFace, MyOtherFace {  // Noncompliant
  //...
}
----

=== Compliant solution

[source,java]
----
public interface MyFace {
  // ...
}

public interface MyOtherFace extends MyFace {
  // ...
}

public class Foo implements MyOtherFace {
  //...
}

=== Message

"yyy" is a "xxx" so "xxx" can be removed from the extension list.

"xxx" is listed multiple times.

"Object" should not be explicitly extended.
