== Why is this an issue?
|
|
|
|
When a type variable or a wildcard declares an upper bound that is ``++final++``, the parametrization is not generic at all because it accepts one and only one type at runtime: the one that is ``++final++``. Instead of using ``++Generics++``, it's simpler to directly use the concrete ``++final++`` class.

=== Noncompliant code example
|
|
|
|
[source,java]
|
|
----
|
|
public static <T extends String> T getMyString() { // Noncompliant; String is a "final" class and so can't be extended
|
|
[...]
|
|
}
|
|

=== Compliant solution
|
|
|
|
[source,java]
|
|
----
|
|
public static String getMyString() { // Compliant
|
|
[...]
|
|
}
