Question

I was wondering if there is a framework to read the data that comes in the json of google maps Directions? type, take the data and put in variables that I can take and use in the rest of the application

Answer 1

You can use the Google Gson.

With it, you define a class and it populates all attributes for you. For example:

public class Pessoa {

    private String nome;
    private int idade;

    public String getNome() {
        return nome;
    }

    public void setNome(String nome) {
        this.nome = nome;
    }

    public int getIdade() {
        return idade;
    }

    public void setIdade(int idade) {
        this.idade = idade;
    }
}

Considering the JSON:

{  
   "nome":"Joao",
   "idade":"25"
}

So you can do:

Gson gson = new Gson();
Pessoa pessoaDoJson = gson.fromJson(jsonString, Pessoa.class);

And Gson will transfer the JSON values to the object attributes pessoaDoJson.

If you want, you can do the reverse path as well: given a populated object, create a JSON:

Pessoa p = new Pessoa();
p.setNome("Joao");
p.setIdade(25);

String json = gson.toJson(p);

//o valor da variável json é: { "nome":"Joao", "idade":"25" }

EDIT:

For ease, you can use something like the jsonSchema2Pojo to build your JSON-based POJO.
