Question: if (input.charAt(i) == '1'|| input.charAt(i) == '2'|| input.charAt(i) == '3'|| input.charAt(i) == '4'|| input.charAt(i) == '5'|| input.charAt(i) == '6'|| input.charAt(i) == '7'|| input.charAt(i) == '8'||

if (input.charAt(i) == '1'|| input.charAt(i) == '2'|| input.charAt(i) == '3'|| input.charAt(i) == '4'|| input.charAt(i) == '5'|| input.charAt(i) == '6'|| input.charAt(i) == '7'|| input.charAt(i) == '8'|| input.charAt(i) == '9') { //some code }

how can I shorten this so that instead of writing a input.char() for each so I can have:

if (input.charAt(i) == '1', '2', '3','4' .... ?

Thank you
