Tutoriais - Programação Orientada a ObjetosDesenvolva uma classe chamada Square para representar um quadrado, ou seja, um quadrilátero regular com quatro lados de mesmo comprimento. A classe possui um único atributo denominado side, do tipo double, que representa o lado do quadrado. O construtor da classe recebe como parâmetro o lado do quadrado, cujo valor deve ser maior ou igual a zero. O lado do quadrado pode ser obtido pelo usuário por meio do método getSide(). A classe também apresenta os métodos area(), diagonal() e perimeter(), que retornam a área, a diagonal e o perímetro do quadrado, respectivamente. A área de um quadrado de lado l é obtida pela fórmula l2. A diagonal de um quadrado de lado l é obtida pela fórmula √2 * l. O perímetro de um quadrado de lado l é obtido pela fórmula 4 * l.
