Hi,
After the declaration:
char[] c = new char[100];
what is the value of c[50]?
a) 50
b) 49
c) '\u0000'
d) '\u0020'
e) " "
f) cannot be determined
g) always null until a value is assigned
I thought the answer is 'c' as characters are initialised to '\u0000'. Am I wrong?
Because this is not the right answer and the key to answers is not provided!
Regards,
Kapil

Hope this helps. Correct me if I am wrong.<p>Cheers <img src="smile.gif" border="0"> ,<br />Kapil

Here is an example to proove you are right:
Character class have
public static int getNumericValue(char ch) which
Returns the Unicode numeric value of the character as a nonnegative integer. If the character does not have a numeric value, then -1 is returned. If the character has a numeric value that cannot be represented as a nonnegative integer (for example, a fractional value), then -2 is returned.
