Java: parse int value from a char

Question

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).

Answer 1

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.
