I do not understand your reference to "non-abstract methods". The methods
of an interface are *abstract* by definition.

Java interfaces specify the methods that an implementing class must
define, including the types of the arguments they accept, the return type,
and the checked exceptions that the methods may throw. But there is no
way that they can specify thread safety.

Interfaces cannot specify that a method is synchronized.

No. You are taking my statement out of context. If you will re-read the
thread, you should be able to understand the context.

You seem rather combative. Is there a reason for this?
