Practical Java Praxis 65: Use Inheritance or Delegation to Define Immutable ClassesPeter Haggar
Because the immutable interface exposes only the nonmutating methods of the underlying class, access to the object through the interface type preserves immutability. This allows you to use the immutable interface to prevent mutation. For example, the following code returns a reference to theMutableCirc...

A @Data class is entirely mutable, which when abused, can increase complexity in an application and limit concurrency usage, both of which hurt the longevity of an application. Lombok has just the fix. Let’s revisit our User class,make it immutable, and add a few other useful Lombok ...

The mutable API provides similar functions as the immutable one with slightly different syntax: mutGraph instead of graph, mutNode instead of node use setters: setDirected instead of directed add instead of width Imperative There is a third possibility to use the API, based on the mutable versi...
In this tutorial, you’ll use achararray to store a password securely. This is a common use case for arrays. Achararray is a better choice thanStringfor storing a password because aStringobject is immutable—that is, it cannot be overridden. So even though you might no longer need a pa...
