Optional orElseThrow
📝 Java
Use Optional's orElseThrow to elegantly retrieve a value or throw a custom exception if it's null.
Java
import java.util.Optional; public class Example { public static void main(String[] args) { Optional<String> opt = Optional.ofNullable(null); String result = opt.orElseThrow(() -> new IllegalStateException("Value is missing!")); System.out.println(result); }
}
