Description

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?
