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)
Try Character.getNumericValue(char)
.
String element = "el5";
int x = Character.getNumericValue(element.charAt(2));
System.out.println("x=" + x);
produces:
x=5
The nice thing about getNumericValue(char)
is that it also works with strings like "el٥"
and "el५"
where ٥
and ५
are the digits 5 in Eastern Arabic and Hindi/Sanskrit respectively.
