Java: parse int value from a char
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.
Try the following:
str1="2345";
int x=str1.charAt(2)-'0';
//here x=4;
if u subtract by char '0', the ASCII value needs not to be known.
That's probably the best from the performance point of view, but it's rough:
String element = "el5";
String s;
int x = element.charAt(2)-'0';
It works if you assume your character is a digit, and only in languages always using Unicode, like Java...
