Converting a char to an integer? 2

[tommyboyau]

Hi Guys,
Is it possible to convert a char to an integer?
This is my situation:
char curChar;
curChar = currentLine.charAt(charCount);

Now i would like to convert curChar to an integer.
Thanks for your help.

Do you want to convert '4' to 4 or '4' to 52?
Then you may just say

int i = curChar;

which is called integral promotion.

Perhaps you want to know why '4' is converted to integer value 52: 52 is the value of ASCII value x34 for the character '4', and the base ASCII is contained in the code used in Java for characters. Contained - not equal!

If you want to get the value 4, you should use method parse() of class java.text.NumberFormat

And I thought I was familiarized with ASCII ...

Anyway, the classical way:

curChar = '4';
int i = Character.getNumericValue(curChar);

// i=4

Cheers,
Dian

Well, you can also use

int four = Integer.parseInt('4');
