Hey guys,
I passed exam with score 92%.
I have long background in C/C++ programming. It took me about 2 month from first page to exam. But my 20 years C++ background helped a lot.
Used two books for preporation:
1. for overview: Herbert Schildt -
Java. The Complete Reference. Ninth Edition
2. for exam preparation: Jeanne Boyarsky, Scott Selikoff - OCA: Oracle Certified Associate Java SE 8 Programmer I
The second one is a great book for exam preparation. it tells you exact what you need to learn for exam.
