Preparation for OCA 8 newly added objectives over OCA 7

[steve jhonson]

Hi All,
I am preparing for OCA 8. and I have completed "Kathy Sierra - OCA/OCP Java SE 7 Programmer I & II Study Guide"'s OCA part . As i need to finish the additional new objectives for OCA 8,

from objectives mapping i found

1) OCA 7 : 1.3 Create executable Java applications with a main method; run a Java program from the command line; including console output.  is now  -->     OCA 8:  1.3 + new topic

2) OCA 7 : 1.5 Compare and contrast the features and components of Java such as: platform independence, object orientation, encapsulation, etc.    is now  -->  OCA 8:   n/a - new topic

3) OCA 7 : 2.5 Use call methods on user-created wrapper class objects (grammatical error reported to Oracle - think this means primitive wrappers    is now  -->      OCA 8:  n/a - new topic

4) OCA 7 : 9.3 Create and manipulate calendar data using classes from java.time.LocalDateTime, java.time.LocalDate, java.time.LocalTime, java.time.format.DateTimeFormatter, java.time.Period     is now  -->     OCA 8:  n/a - new topic

5) OCA 7 : 9.5 Write a simple Lambda expression that consumes a Lambda Predicate expression     is now  -->    OCA 8:   n/a - new topic

I need to complete these objectives too so that i can go for mock exams and review. But i dont have any other books except "K&B OCA 7" which i mentioned above. I can search online or oracle docs for 4) DateTime API  and 5) Lambda Expressions for preparation but i have no idea above first 3 objectives in my list how to prepare? Are there any links for preparation for newly added OCA 8 objectives ?
And also are there any objectives that are added in OCA 8 apart from above mentioned 5 topics?

Hi steve jhonson,

1) OCA 7 : 1.3 Create executable Java applications with a main method; run a Java program from the command line; including console output.  is now  -->     OCA 8:  1.3 + new topic

For the above objective , you need to know how to compile java file and how to run it. I mean javac , java commands . You also need to learn about main  javac commnad  options (ex: javac -cp Test.java) and java commnad  options .

2) OCA 7 : 1.5 Compare and contrast the features and components of Java such as: platform independence, object orientation, encapsulation, etc.    is now  -->  OCA 8:   n/a - new topic

For the above objective , You will get knowledge when you are preparing Java features and  OOPS concepts.

5) OCA 7 : 9.5 Write a simple Lambda expression that consumes a Lambda Predicate expression     is now  -->    OCA 8:   n/a - new topic

For the above objective , I can suggest you the link Java8_Lambda_Expressions.

3) OCA 7 : 2.5 Use call methods on user-created wrapper class objects (grammatical error reported to Oracle - think this means primitive wrappers    is now  -->      OCA 8:  n/a - new topic
4) OCA 7 : 9.3 Create and manipulate calendar data using classes from java.time.LocalDateTime, java.time.LocalDate, java.time.LocalTime, java.time.format.DateTimeFormatter, 

You can also get good information Oracle website Java_Tutorial

It would be better if you refer OCAJP8 by sybex which is written fully OCAJP8 point of view.

Hope this helps !

Thank you Narayana,

Thanks for useful lines

It would be better if you refer OCAJP8 by Sybex which is written fully OCAJP8 point of view

I will try to get that book from my friend, but as I covered almost all topics of OCA 7 from K&B,could you please tell me which are the specific topics in Sybex book that i needed to concentrate more in OCA 8 point of view?
I am Revising K&B as of now. Thank you in advance.

Read the whole OCAJP8 by sybex 3 or 4 times. Each and every point in that book is useful to exam. I want to add one thing . In Java 8, default ,static methods are added interfaces which is in exam. That concept may not be covered by the book which you are referring.So Read all chapters in OCAJP 8 by Sybex.
