Question

categoryCheck: {
        for (String allowedCategory : allowedCategories) {
            if (evt.getLoggerName().startsWith(allowedCategory)) {
                break categoryCheck;
            }
        }
        return false;
    }

Is it any ideas how to rewrite this code without using labels and without considerable increasing of it?

Answer 1

I’d probably put it into its own method:

// I've guessed at the types...
public boolean isCategoryAllowed(Event evt, Iterable<String> allowedCategories) {
    for (String allowedCategory : allowedCategories) {
        if (evt.getLoggerName().startsWith(allowedCategory)) {
            return true;
        }
    }
    return false;
}

Then change the calling code to simply call the method:

if (!isCategoryAllowed(evt, allowedCategories)) {
    return false;
}
