For example you have class Person. Person is a POJO for REST-service (for instance, for using with retrofit).

class User {
  public static final String firstName = "", lastName = "";
}

This line of code creates two read-only fields. It’s necessary to assign initial values because every field is final. But there’s another way to do the same thing:

class User {
  public static final String firstName, lastName;

  public User() {
    firstName = "";
    lastName = "";
  }
}

It’s hard to believe, but second – is the only right way to create class.

For example, you’re creating class instance:

User user = SomeReflection.getUser();
// user.lastName.equals("Username")
callFunction(user); // in this function user.lastName.equals("") for 1st method

I think it depends on JVM but it’s truth for Android ART.

There’s situation when you use android productFlavors with individual applicationId for each application (that’s reasonable when you generating some similar apps for Google Play) and using Android Annotations framework (AA).
