+# [Adapter to java.util.List.of](https://www.codewars.com/kata/adapter-to-java-dot-util-dot-list-dot-of "https://www.codewars.com/kata/65e5ef770a978e003e36f16a")
+
+If you're an experienced Java programmer, you've likely come across `List.of`, but it often frustrates newcomers since the returned list is
+immutable and doesn’t allow adding, removing, or modifying elements. This happens because the object implements the `java.util.List`
+interface but delegates its method calls to another implementation behind the scenes, demonstrating the Adapter pattern that allows
+different interfaces
+to work together by translating method calls.
+
+Your task is to create a method that takes an array (or varargs) and returns a `List` structure that keeps the data immutable, similar to
+how `List.of` works.
+
+You cannot use:
+ - List.of
+ - any method named .of
+ - the new operator, except when creating Exceptions
+
+You can find more info on [List.of()](https://docs.oracle.com/en/java/javase/21/docs/api/java.base/java/util/List.html#of()) in the Java docs.
