>             Project: Commons Lang
>          Issue Type: Improvement

> For now, join(int[], char) is working well.
>  However, the same join method called with a string delimiter behaves 
> differently : it returns a single memory address which is not the desired 
> behavior.
>  I think that, for coherence, calling StringUtils with a char or String 
> delimiter should return the exact same value.
> Ex :
> {code:java}
> CLASSPATH="./commons-lang3-3.11.jar" jshell 
> |  Welcome to JShell -- Version 11.0.8
> jshell> import org.apache.commons.lang3.StringUtils
> jshell> int[] arr = {1, 2, 3, 4, 5, 6, 7};
> jshell> String result = StringUtils.join(arr, '-');
> result ==> "1-2-3-4-5-6-7"
> jshell> String result = StringUtils.join(arr, "-");
> result ==> "[I@69663380-"
> {code}
