I'm having a question about using Hashmap of Java. On that occasion, I have a class with the Hashmap custo attribute.
In this class, I need to create a constructor and in this constructor, I need to request the insertion of 3 integers that will make up my cost (gold, wood and diamond).
My question is: how do I request these 3 data in order to fill them at my cost? And how do I display and use them later?
I believe that's what you want.

//CRIANDO O MAP CUSTO
HashMap<String, Integer> custo = new HashMap<String, Integer>();
//PEDINDO A INFORMAÇÃO PARA O USUÁRIO
System.out.println("DIGITE A QUANTIDADE DE OURO");
Scanner readOuro = new Scanner(System.in);
//OBTENDO A INFORMAÇÃO DO TECLADO
Integer qtdOuro = readOuro.nextInt();
//INSERINDO A QUANTIDADE DE OURO AO MAPA COM A CHAVE OURO
custo.put("OURO", qtdOuro);
//FAZENDO A MESMA COISA PARA MADEIRA E DIAMANTE
System.out.println("DIGITE A QUANTIDADE DE MADEIRA");
Scanner readMadeira = new Scanner(System.in);
Integer qtdMadeira = readMadeira.nextInt();
custo.put("MADEIRA", qtdMadeira);
System.out.println("DIGITE A QUANTIDADE DE DIAMANTE");
Scanner readDiamante = new Scanner(System.in);
Integer qtdDiamante = readDiamante.nextInt();
custo.put("DIAMANTE", qtdDiamante);
