Alphabet constant in Java?

Question

I have a situation where I need to find a letter's index in the alphabet. In Python I could use string.ascii_lowercase or string.ascii_uppercase. Is there something similar in Java?

Obviously I could do:

private static char[] alphabet = "abcdefghijklmnopqrstuvwxyz".toCharArray();

But after so much Python, it makes me wonder if this is built in somewhere.

Answer 1

You can get the index like this:

char lowercaseLetter = ...
int index = lowercaseLetter - 'a';
