Java: parse int value from a char


java parsing char int parseint

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...
