def format_name(first, last) if !(first.instance_of?(String) && last.instance_of?(String)) raise "arguments must be strings" end first.capitalize + " " + last.capitalize end first_name = 42 last_name = true begin puts format_name(first_name, last_name) rescue # do stuff to rescue the "arguments must be strings" exception... puts "there was an exception :(" end

raise는 예외를 어떻게 가져오는지에 대해서 처리하고 begin...rescue는 예외를 어떻게 반응할지에 대해 작동한다.
