I've heard that Java bytecode actually doesn't support any kind of unnamed classes. How does javac translate unnamned classes to named ones?

No, anonymous types cannot implement an interface. We need to create your own type. Anonymous types provide a convenient way to encapsulate a set of read-only properties into a single object without having to explicitly define a type first.
You can't. The only way to be able to call multiple methods is to assign the anonymous class instance to some variable.
Since anonymous inner class has no name, an anonymous inner class cannot have an explicit constructor in Java.
It synthesizes a name of the form EnclosingClass$n, where "n" is a counter for anonymous classes in EnclosingClass. Because using $ in identifiers is discouraged, these names should not collide with any user-specified names.
