Question about using Hashmap

Question

I have a question about the use of Hashmap of Java. On this occasion, I have a class with the attribute Hashmap custo.

In this class, I need to create a builder and in this builder, I need to request the insertion of 3 integers that will compose my cost (gold, wood and diamond).

My question is: how do I request this 3 data in order to fill them in my cost? And how do I display and use the same later?

Answer 1

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);
