Incrementing Char Type In Java

Question

While practicing Java I randomly came up with this:

class test
{
    public static void main(String arg[])
    {
        char x=\'A\';
        x=x+1;
                


        

Answer 1

in case you want it to be just a-z.

private char getNextChar(char c) {
    return (char)((c + 1 - 'a') % ('z' - 'a' + 1) + 'a');
}

this avoids it overflows.
