How can I raise an exception in Java’s if-else statement?

Nice point, I’ve worked a lot with situations where data can be null or missing. In those cases, Java 8’s Optional is a game-changer for conditionally java raise exception without cluttering your code with more if-else checks. Here’s how you can use it:

Optional.ofNullable(some_condition)
        .filter(c -> c)
        .orElseThrow(() -> new RuntimeException("some_condition was false, throwing exception!"));

This is really handy because it eliminates the need for verbose condition checks and makes your code more declarative. It works perfectly for values that might be absent or null, such as method return values. So, if you want a more elegant approach, especially for handling optional or nullable data, this is a great way to go!"
