It seems that s[1] somehow misses the s1.equals("") comparison. The
thing to check is what and how many characters s[1] contains. Add
something like:
int nLength = s[1].length()
System.out.println("Length of s[1]: " + nLength);
for (int i = 0; i < nLength; i++)
{
System.out.println("s[1] character " + i + ": " + (int)
s[1].charAt(i));
}
