How do I pass custom message for the exception when thrown using orElseThrow method?

We can pass the custom message to the Exception constructor when created as shown below.

orElseThrow(() -> new EntityNotFoundException("Entity doesn't Exist"));

Example:

import java.util.Optional;

public class OrElseThrowCustomMessage {
    public static void main(String[] args) {
        Optional<String> str = Optional.empty();
        str.orElseThrow(()-> new NullPointerException("Empty String"));
        System.out.println(str);
    }
}
