Comparing chars in Java

Question

I want to check a char variable is one of 21 specific chars, what is the shortest way I can do this?

For example:

if(symbol == (\'A\'|\'B\'|\'C\')){}         


        

Answer 1

pseudocode as I haven't got a java sdk on me:

Char candidates = new Char[] { 'A', 'B', ... 'G' };

foreach(Char c in candidates)
{
    if (symbol == c) { return true; }
}
return false;
