Hi could someone tell me at what point I'm getting confused If I have char c = 'g' int i = c; Then i is 103 which as far as I am aware is the Unicode value of 'g' But if I use int i = Character.getNumericValue('g'); Which in the docs says it returns the unicode numeric value of a character I get 16. If I do System.out.println('\u0103') I get a '?' and System.out.println('\u0016'); I get a strange symbol. My head hurts!!!
Ah, but you might be missing some of the basics of unicode. The "numeric value" referred to is not what you think it is. The number corresponding to the Unicode character would simply be (int)c! The getNumericValue() method returns the "numeric value" Unicode property, i.e. the value represented by the character in a number. You probably know that in a hexadecimal (base-16) number, the letter 'f' is a digit representing the number 15. In exactly the same way, if your number is base-17 or higher, the letter 'g' is a digit representing the number 16. That is what getNumericValue() returns. The Character class gives access to a number of Unicode properties like this; other examples would be the type (aka category) and the case. - Peter [ March 05, 2003: Message edited by: Peter den Haan ]
