How can I get the UTF8 code of a char in Java ? I have the char 'a' and I want the value 97 I have the char 'é' and I want the value 233
here is a table for more values
I tried Character.getNumericValue(a) but for a it gives me 10 and not 97, any idea why?
This seems very basic but any help would be appreciated!

If char variable contains int value, we can get the int value by calling Character. getNumericValue(char) method. Alternatively, we can use String. valueOf(char) method.
To access character of a string in Java, use the charAt() method. The position is to be added as the parameter. String str = "laptop"; Let's find the character at the 4th position using charAt() method.
Yes, char is just like any other primitive type, you can just compare them by == .
char is actually a numeric type containing the unicode value (UTF-16, to be exact - you need two chars to represent characters outside the BMP) of the character. You can do everything with it that you can do with an int.
Character.getNumericValue() tries to interpret the character as a digit.

You can use the codePointAt(int index) method of java.lang.String for that. Here's an example:
"a".codePointAt(0) --> 97
"é".codePointAt(0) --> 233
If you want to avoid creating strings unnecessarily, the following works as well and can be used for char arrays:
Character.codePointAt(new char[] {'a'},0)
