What is the best practice for using the NOT operator in IF conditions in Java?

Sometimes using NOT in Java can lead to complex, hard-to-read nested conditions. Instead of:

if (!user.isBlocked()) {
    if (!user.isInactive()) {
        sendWelcomeMessage();
    }
}
Use early returns:

if (user.isBlocked()) {
    return;
}
if (user.isInactive()) {
    return;
}
sendWelcomeMessage();Copy code

This way, the main logic is not buried inside multiple conditions, making the code more intuitive.
