Accessing the private Fields

Question

I have 2 Java classes

JavaOne.class
JavaTwo.class

Both these classes are public. Inside the JavaTwo.class, I have a static class JavaThree which extends SQLiteOpenHelper. Inside JavaThree I have a private field say Gender

Public class JavaTwo{
    static class JavaThree extends SQLiteOpenHelper{
           private static final String Gender;
    }
}

How can I access the value of Gender field from JavaOne.class

Accodring to this, http://developer.android.com/training/basics/data-storage/databases.html it's better to use `public` when it's ex. table name or database name. It's final, co don't be afraid, no one can change it ;) — rzysia, Mar 13 '15 at 08:03
@rzysia - learnt this after some time. private only when necessary — user3314337, Mar 13 '15 at 13:28

Try adding a getter method to the class

public String getGender()
{
    return Gender;
}

You can access it using an accessor method or (getter() method) inside your JavaThree class, like the following:

  public String getGender() {
      return this.Gender;
  }

Take a look at Accessors and Mutators for further information about their use.

And note that if you use the final keyword with a variable it will be considered as a constant.

Referring to Final Keyword In Java:

If you make any variable as final, you cannot change the value of final variable(It will be constant).
