What is an immutable class in Java?

An immutable class is a class whose instances, once created, cannot have their internal state modified.

"I just need users to go to different pages after login."
Famous last words.
3 days of Laravel role-based authentication later:
- Middleware not registering
- auth() ->user() has no 'isAdmin()' method
- 403 errors everywhere

Return Optional and make the intent clear:

public Optional<User> findUserById(Long id) {
// caller knows it might be empty ✅
}
```

[S-TECH Solutions @SentinelleTech1]

Java developers: Stop using null checks everywhere.

Instead of this:
if (user != null && user.getName() != null) {
return user.getName();
}
return "Unknown";

Use:
return Optional.ofNullable(user)
.map(User::getName)
.orElse("Unknown");

[S-TECH Solutions @SentinelleTech1]

Bonus: Optional also works great for method returns

Instead of returning null and forcing callers to check:

public User findUserById(Long id) {
// returns null if not found ❌
}

Here’s a simple Java program that generates a checkerboard pattern pixel by pixel!
It’s not a game board, it’s pure math and logic visualized.
