Determine if string starts with letters A through I

Question

I\'ve got a simple java assignment. I need to determine if a string starts with the letter A through I. I know i have to use string.startsWith(); but I don\'t want to write,

Answer 1

You don't need regular expressions for this.

Try this, assuming you want uppercase only:

char c = string.charAt(0);
if (c >= 'A' && c <= 'I') { ... }

If you do want a regex solution however, you can use this (ideone):

if (string.matches("^[A-I].*$")) { ... }
