Joerg Schaible commented on LANG-701:
-------------------------------------
bq. the input array should be of Object type, not String, which will cause a
stack overflow with the proposed APIs because the boolean arg will go into the
Object array. This would not happen with a String array but it would greatly
reduce the functionality.
The input array could be at least CharSequence then.

> final String apple = "apple";
> final String banana = "banana";
> final String orange = "orange";
> final String expected = apple + SPACE + banana + SPACE + orange;
> final String actual = join(SPACE, apple, banana, orange);
> final int expLength = expected.length();
> final int actLength = actual.length();
> assertEquals(expLength, actLength);
> assertEquals(expected, actual);

> I missed the functionality of joining strings with the space separator in one
> line. BTW, why space ' ' not a constant field anywhere?
