Comunicação serial, erro ao imprimir variável

Pessoal, estou tentando imprimir uma variável que monto a partir de dados recebidos pela serial, porém já tentei de varias maneiras ( ao meu nível de conhecimento) e não estou conseguindo fazer a impressão. Vou compartilhar código que montei baseado em exemplos.

ele não me deixa imprimir desta maneira:
System.out.println("" +serial.getTemperatura())
