How many classes are there in Java standard edition?

Question

I am curious how many classes are there in Java standard library. Perhaps someone knows an approximate number?

Answer 1

I see 3762 within Java 8 as following

All Classes ( Outer as well as Inner ) , Enums and Interfaces -  3762
All except Inner Classes                                      -  3462
Only Classes ( Outer + Inner + Abstract + Enum )              -  2963
Interfaces                                                    -  799
Enum                                                          -  93  

Moreover , Here is the list of classes / interfaces introduced with each version - http://qr.ae/Q2baW
