Scala is translated to standard Java bytecodes, aligning features directly with Java constructs. Traits become Java interfaces, and value types like Int may map to Java int or wrapper classes. Singleton objects are converted to Java classes suffixed with '$', with direct or generated translations for trait implementations.
Scala's annotations, such as @deprecated and @volatile, align with Java's equivalent modifiers, ensuring seamless interoperability. Serialization annotations bridge Scala and Java compatibility for cross-language projects.
