Tutoriais - Programação Orientada a ObjetosDesenvolva uma classe chamada Dodecahedron para representar um dodecaedro, ou seja, um poliedro regular de doze faces, considerado um dos cinco Sólidos Platônicos. A classe possui um único atributo denominado edge, do tipo double, que representa a aresta do dodecaedro e cujo valor deve ser maior ou igual a zero e menor ou igual a trinta. A classe possui dois construtores: o primeiro configura a aresta do dodecaedro com o valor padrão 1.0, e o segundo recebe como parâmetro a aresta do dodecaedro. A aresta do dodecaedro pode ser obtida e alterada pelo usuário por meio dos métodos getEdge() e setEdge(), respectivamente. A classe também apresenta os métodos area() e volume(), que retornam a área e o volume do dodecaedro, respectivamente. A área de um dodecaedro de aresta a é obtida pela fórmula 3 * √(25 + 10 * √5) * a2. O volume de um dodecaedro de aresta a é obtido pela fórmula 1 / 4 * (15 + 7 * √5) * a3.
