Can someone explain to me this code!

Question

public final static class SessionType
public static final SessionType APP_BASE = new SessionType();
public static final SessionType ADVANCED_APP_BASE = new SessionType();
public static final SessionType THREAD_BASE = new SessionType();
public static final SessionType USER_DEFINED = new SessionType();
private SessionType()
in the another class, i write a statement :
private static SessionType sessiontype = SessionType.APP_BASE;
then, what is the value of the sessiontype ????
or, did the virtual machine allocate any memory space to variable sessiontype ？

Answer 1

if i instantiate an instance of the type SessionType, since the class variable declared as static is not bind to the instance of the class, so the instance of the SessionType did'nt have the variable APP_BASE, ADVANCED_APP_BASE, ......,so the instance of the SessionType only obtain the Constructor of the class, is this right ??!!!
