// Suppose we have a class "User" that saves data to Sqlite database.
// According to my understanding, Sqlite doesn't save boolean type. So we save integer (1 = true  0 = false)
// Now if the property "isUserAGoat" is public, any class can change its value to any integer,
// whereas it is supposed to be only 1 or 0
class User {
  public int isUserAGoat;
}

// But if we make this property private and give public setter/getter, we can make sure that its value can only be 1 or 0
class User {
  private int isUserAGoat;

  public boolean isUserAGoat() {
    return isUserAGoat == 1;
  }

  public void setUserAGoat(boolean yes) {
    isUserAGoat = yes ? 1 : 0;
  }
