Answer
Immutability ensures consistent and reliable data handling.
Immutability in Java is crucial for value-like data, such as a customer's profile, because it prevents data from being altered once created. This leads to fewer bugs related to unexpected changes. For example, if a customer's profile is immutable, their name and email cannot be changed unintentionally, ensuring data integrity throughout the application's lifecycle. Consider a class with fields declared as 'final' and no setter methods, protecting the object state once it's initialized.
