java AC 0.171 dont use String.toCharArray

btw WA7 (add line 2):
1. for (i=p; i<lena; i++)
2. if (a[i]==' ') out2.print(' '); else
3.  out2.print('_');

 ab ab abcabcabcd         |
a b              bcd         |
 a_ _b _______bcd         |

so WA 7 controverses with "The words in both utterances are separated with exactly one space; there are no leading or trailing spaces in each line."
