How does Scalaâ€™s case classes differ from Javaâ€™s regular classes?
Scala's case classes are used for data storage and are similar to Java classes but don't require constructors.
That's partially correct. Case classes do store data, but they also automatically generate methods like `copy` and `apply` and are immutable.
Can you explain how `copy` works in Scalaâ€™s case classes and how it differs from Java's approach to object cloning?
