/*
Faça uma classe genérica Par que tem 2 parâmetro de
tipo – F e S, cada um representando respectivamente o
tipo do primeiro elemento e o tipo do segundo elemento
do par. Adicione os métodos set e get.
O cabeçalho da classe deve ser: public class Par
<F,S>.
Crie um array de Par e verifique se o método printArray
irá funcionar. Caso não funcionar, reescreva o método
pra que imprima os todos os pares do array
