Java: parse int value from a char

I just want to know if there's a better solution to parse a number from a character in a string (assuming that we know that the character at index n is a number).

String element = "el5";
String s;
s = ""+element.charAt(2);
int x = Integer.parseInt(s);

//result: x = 5

(useless to say that it's just an example)

Answer Source

Try Character.getNumericValue(char).

String element = "el5";
int x = Character.getNumericValue(element.charAt(2));
System.out.println("x=" + x);



The nice thing about getNumericValue(char) is that it also works with strings like "el٥" and "el५" where ٥ and are the digits 5 in Eastern Arabic and Hindi/Sanskrit respectively.
