Moreover, if MessageService were actually mutable, but multiple threads only have read-only access to it, it’s thread-safe as well. As we can see, immutability is just another way to achieve thread-safety. 4. Thread-Local Fields In Object-Oriented Programming (OOP), objects actually need...

This public method declared in public enum unconditionally sets enum field, thus this field can be changed by malicious code or by accident from another package. Though mutable enum fields may be used for lazy initialization, it's a bad practice to expose them to the outer world. Consider rem...
