For this, our User class must implement the Cloneable interface: public class User implements Cloneable The next method, cloning, is a way to create an exact copy of an object. In this case, we’re using reflection to find and invoke a constructor of the User class. Here’s an example of creating our User object using reflection: void whenInitializedWithReflection_thenInstanceIsNotNull() Reflection is a mechanism we can use to inspect classes, fields, and methods at run-time. Then the object lives its life, and provides us with access to its methods and fields.įinally, when it’s no longer needed, the garbage collector destroys it. In conclusion, an object is first created from a class, usually using the keyword new.
