How to set instance variable using the read value of a Scanner?

Question

To declare the value of a class instance variable Paciente by class Main with the Scanner in Java?

Codes:

public class Paciente{

  private double cod;
  private String nome;

  public getNome(){
      return this.nome;
  }

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

---

import java.util.Scanner;

class Main {
    public static void main(String[] args) {
        Scanner input = new Sacanne(System.in);
        Paciente p01 = new Paciente();

        System.out.printlm("Digite o nome do Paciente: ");
        String nomedopaciente = input.nextLine();
        p01.setNome(nomedoPaciente);
    }
}

Answer 1

This code has a huge amount of typing errors (and des organization that does not prevent the compilation) and this is what is preventing it to work, but I decided to answer (although it may be innocuous) because the code has several conceptual errors.

Almost every class should have one builder that makes sense and initializes an object in a valid state.

Almost always the use of getters are unnecessary or inappropriate and should give preference to methods that do something more meaningful and setters make less sense because in general most of the data should not be changed, but if it can be then it should be by a method that has more semantics. Not to mention that in many cases accessing the direct field would be simpler and easier, just know what you are doing. Understand more the subject following links in another question.

I would need to create a mechanism to control the code that I switched to whole because it doesn’t make any sense to have one double.

Object-oriented programming is to model objects correctly, with the right concepts, otherwise you don’t need this complexity.

import java.util.Scanner;

class Main {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        System.out.println("Digite o nome do Paciente: ");
        Paciente p01 = new Paciente(1, input.nextLine());
    }
}

class Paciente {
    private int codigo;
    private String nome;
    public Paciente(int codigo, String nome) {
        this.codigo = codigo;
        this.nome = nome;
    }
    public String getNome() { return nome; }
    public void setNome(String nome) { nome = this.nome; }
}

Behold working in the ideone. And in the repl it.. Also put on the Github for future reference.
