Kiruahxh updated LANG-1593:
---------------------------
Description:
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 addresses 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}
