                 Key: LANG-701
                 URL: https://issues.apache.org/jira/browse/LANG-701
             Project: Commons Lang
          Issue Type: New Feature
          Components: lang.text.*
            Reporter: Gabriele Kahlout
            Priority: Minor


<code>
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);
</code>

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