Last Questiion for today I hope char.length

[Anthony Smith]

public static boolean is_special(char value)

{
char[] special_chars = {'#', '$', '%', '&', '*', '.', ','};

for (int i = 0; i!=special_chars.length(); i++)
{
if (value==special_chars[i])
return true;
}
return false;
}

I dont think it likes this line
special_chars.length()

Hi Anthony,
You are correct. The method length is not defined for arrays. It is defined for String however:
String s = "Yesterday";
int i = s.length(); // Equals 9.
You want the field length that is defined for arrays:
String[] as = {"Yesterday", "Today", "Tommorrow"};
int i = as.length; // Equals 3.
Regards,
Manfred.

length is a property of Arrays, so you could use spec_char.length

Yes, length is not a method but a property of arrays so you just need to drop the '()'.
