Private:

Generally used in static member constants such as

Public static final String MINI= "programmer Learning Camp"

From the encapsulation point of view, the suggested variables are defined as private, and then need to be accessed by the outside world, exposing a get method

Private String mini = "programmer learning base"; public String geMini () {return mini;}

Commonly used in architecture design to store variables common to subclasses

Public class BaseXXX {protected String mini;} public class SubXXX extends BaseXXX {public String getMini () {return mini;}} access modifiers on how to understand Java are shared here.
