Question

How I can access the Name field?

public class Animals {

    public enum animal{
        a1("CAT", 4),
        a2("DOG", 4);
    }

    String Name;
    int E;
    public animal(String Name, int E){
        this.Name = Name;
        this.E    = E;
    }
}

Answer 1

This can be done, but you have a number of syntax errors. The key is to provide getter methods for the enum member variables.

public enum Animal {
  a1("CAT", 4), a2("DOG", 4);
  private String Name;
  private int E;

  private animal(String Name, int E)
  {
    this.Name = Name;
    this.E = E;
  }

  public String getName() {
    return Name;
  }

  public int getE() {
    return E;
  }
}

You could then access these values anywhere in the rest of your program.

Animal.a1.getName();
