get char value in java

Question

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

Answer 1

My method to do it is something like this:

char c = 'c';
int i = Character.codePointAt(String.valueOf(c), 0);
// testing
System.out.println(String.format("%c -> %d", c, i)); // c -> 99

Answer 2

This produces good result:

int a = 'a';
System.out.println(a); // outputs 97

Likewise:

System.out.println((int)'é');

prints out 233.

Note that the first example only works for characters included in the standard and extended ASCII character sets. The second works with all Unicode characters. You can achieve the same result by multiplying the char by 1. System.out.println( 1 * 'é');
