Quick Answer
Lambda bodies can only throw unchecked exceptions. To handle checked exceptions in lambdas: wrap in a try-catch inside the lambda, or create a helper functional interface that declares the checked exception, or use a utility method that wraps checked exceptions as unchecked. Alternatively, wrap the checked exception in a RuntimeException: e -> { try { ... } catch (IOException e) { throw new UncheckedIOException(e); } }
Answer
Checked exceptions must be handled inside lambda. Custom functional interfaces can declare throws clauses. Ensures clean functional-style error handling.
